    RESTful Resource Handling

    Representational State Transfer (REST) is an architectural style for distributed application.

    $routes->resource('photos');

    // Equivalent to the following:
    $routes->get('photos/new', 'Photos::new');
    $routes->post('photos', 'Photos::create');
    $routes->get('photos', 'Photos::index');
    $routes->get('photos/(:segment)', 'Photos::show/$1');
    $routes->get('photos/(:segment)/edit', 'Photos::edit/$1');
    $routes->put('photos/(:segment)', 'Photos::update/$1');

    $psr4 = [
    'Config' => APPPATH . 'Config',
    APP_NAMESPACE => APPPATH,
    'App' => APPPATH,
    'Auth' => APPPATH . 'ThirdParty/Auth',
    ];

    Set up the email in app/Config/Email. Fill the $fromEmail and $fromName as well! I suggest you to use mailtrap.io for local development.
    Enable CSRF in app/Config/Filters.
    Make sure that your database is set in .env file or in app/Config/Database.php. Install the users table by running the following command in your project root:
    php spark migrate
    Visit /register on your local server to begin.

    Code Igniter Trick : How to call Function inside a View

    Code Igniter is MVC, that a thing that all people know.
    That make it is a bad idea to call a function from controller or model.

    The only function that available is the one from helper.
    But you can use a function inside a model actually :D.

    Okey, lets explore those choiches :

    I would like to answer this question as this comes all times up in searches --

    You can call a controller method in view, but please note that this is not a good practice in any MVC including codeigniter.

    Your controller may be like below class --

    $CI =& get_instance();
    $CI->abc($id) ;

    Using Function From Helper

    You just need to load the helper in any place before call the function needed.
    You can call it inside your controller, model or view.
    The only limitation is you cannot use $this on any function of helper.–> Create a helper inside your “application/helper” folder. Eg : myhelpername_helper.php
    –> Create the function inside the helper,
    eg : function my_function(){ echo ‘Hi’; }
    –> inisiate it inside your view (or your controller) : $this->load->helper(‘myhelpername’);
    –> Call the function. Eg : my_function();
    Remember not to use “$this->my_function();” because helper is off OOP side of your code.
    Using Function From Model
    The bright-side of this option is you can use “$this”, means all variable of CI object is available.
    –> Remember to inisiate the model in your controller.
    –> Say your model is “mymodelname_model.php” and the function is “mymodelname”, you can call it inside your view like this :
    $this->mymodelname->mymodelname();

    You can call a controller function with AJAX on your view. In this case, I'm using the jQuery library to make the call

    Chapter 1: Using PHP

    Installing a web server

    To view PHP code in a browser the code first has to run a distribution of the popular Apache web server called XAMPP or usbwebserver which comes pre-installed with PHP, Perl and MySQL.

    Embedding PHP

    PHP code can be embedded anywhere in a web document in one of four different ways. The standard notation is to delimit the code by “”. This is called a PHP
    code block, or just a PHP block.

    <? = php

    ?>

    Outputting text

    Keep in mind that text output will only be visible on the web page if it is located within the HTML body element.

    <? = php
    echo "Hello World";
    print "Hello World"
    ?>

    Comments

    Comments are used to insert notes into the code and will have no effect on the parsing of the script. PHP has the two standard C++ notations for single-line (//) and multi-line
    (/* */) comments. The Perl comment notation (#) may also be used to make single-line comments.

    <? = php

    // single-line comment
    # single-line comment
    /* multi-line
    comment */
    ?>

    Chapter 2: Variables

    Defining variables

    A variable starts with a dollar sign ($) followed by an identifier, which is the name of the variable.

    $myVar;

    A value can be assigned to a variable by using the equals sign, or assignment operator (=). The variable then becomes defined or initialized.

    $myVar = 10;

    Data types

    PHP is a variable’s data type will change automatically to be able to hold the value it is assigned.

    $myVar = 1; // int type
    $myVar = 1.5; // float type

    Data Type  = Category = Description
    int = Scalar = Integer
    float = Scalar = Floating-point number
    bool = Scalar = Boolean value
    string = Scalar = Series of characters
    array = Composite = Collection of values
    object = Composite = User-defined data type
    resource = Special = External resource
    callable = Special = Function or method
    null = Special = No value

    Integer type

    An integer is a whole number. They can be specified in decimal (base 10), hexadecimal $myInt = 1234; // decimal number

    $myInt = 0b10; // binary number (2 decimal)
    $myInt = 0123; // octal number (83 decimal)
    $myInt = 0x1A; // hexadecimal number (26 decimal)(base 16), octal (base 8) or binary (base 2) notation.

    Floating-point type

    The float or floating-point type can store real numbers. These can be assigned using either decimal or exponential notation.

    $myFloat = 1.234;
    $myFloat = 3e2; // 3*10^2 = 300

    Commonly can hold approximately 14 decimal digits and a maximum decimal value of 1.8x10 308 .

    Bool type

    The bool type can store a Boolean value, which is a value that can only be either true or false. These values are specified with the true and false keywords.

    $myBool = true;

    Null type

    The case-insensitive constant null is used to represent a variable with no value. Such a variable is considered to be of the special null data type.

    $myNull = null; // variable is set to null

    If evaluated as a bool it becomes false, as a number it becomes zero (0), and as a string it becomes an empty string ("").

    $myInt = $myNull + 0; // numeric context (0)
    $myBool = $myNull == true; // bool context (false)
    echo $myNull; // string context ("")

    Default values

    In PHP it is possible to use variables that have not been assigned a value. Such undefined variables will then automatically be created with the value null.

    echo $myUndefined; // variable is set to null

    Chapter 3: Operators

    Operators are used to operate on values. They can be grouped into five types: arithmetic, assignment, comparison, logical and bitwise operators.

    Arithmetic operators

    The arithmetic operators include the four basic arithmetic operations, as well as the modulus operator (%) which is used to obtain the division remainder.

    $x = 4 + 2; // 6 // addition
    $x = 4 - 2; // 2 // subtraction
    $x = 4 * 2; // 8 // multiplication
    $x = 4 / 2; // 2 // division
    $x = 4 % 2; // 0 // modulus (division remainder)

    Assignment operators

    The second group is the assignment operators. Most importantly, the assignment operator (=) itself, which assigns a value to a variable.

    Combined assignment operators

    A common use of the assignment and arithmetic operators is to operate on a variable and then to save the result back into that same variable. These operations can be shortened
    with the combined assignment operators.

    $x = 0;
    $x += 5; // $x = $x+5;
    $x -= 5; // $x = $x-5;
    $x *= 5; // $x = $x*5;
    $x /= 5; // $x = $x/5;
    $x %= 5; // $x = $x%5;

    Increment and decrement operators

    Another common operation is to increment or decrement a variable by one. This can be
    simplified with the increment (++) and decrement (−−) operators.

    $x++; // $x += 1;
    $x−−; // $x -= 1;

    Both of these operators can be used either before or after a variable.

    $x++; // post-increment
    $x−−; // post-decrement
    ++$x; // pre-increment
    −−$x; // pre-decrement

    The result on the variable is the same whichever is used. The difference is that
    the post-operator returns the original value before it changes the variable, while the
    pre-operator changes the variable first and then returns the value.

    $x = 5; $y = $x++; // $x=6, $y=5
    $x = 5; $y = ++$x; // $x=6, $y=6

    Comparison operators

    The comparison operators compare two values and return either true or false. They are
    mainly used to specify conditions, which are expressions that evaluate to either true
    or false.

    $x = (2 == 3); // false // equal to
    $x = (2 != 3); // true // not equal to
    $x = (2 <> 3); // true // not equal to (alternative)
    $x = (2 === 3); // false // identical
    $x = (2 !== 3); // true // not identical
    $x = (2 > 3); // false // greater than
    $x = (2 < 3); // true // less than
    $x = (2 >= 3); // false // greater than or equal to
    $x = (2 <= 3); // true // less than or equal to

    The identical operator (===) is used for comparing both the value and data type of
    the operands. It returns true if both operands have the same value and are of the same
    type. Likewise, the not identical operator (!==) returns true if the operands do not have
    the same value or are not of the same type. Put another way, the equality operators will
    perform type conversions, whereas the identical operators will not.
    $x = (1 == "1"); // true (same value)
    $x = (1 === "1"); // false (different types)

    Logical operators

    The logical operators are often used together with the comparison operators. Logical and
    (&&) evaluates to true if both the left and right side are true, and logical or (||) evaluates to
    true if either the left or right side is true. The logical not (!) operator is used for inverting
    a Boolean result. Note that for both “logical and” and “logical or” the right side of the
    operator will not be evaluated if the result is already determined by the left side.

    $x = (true && false); // false // logical and
    $x = (true || false); // true // logical or
    $x = !(true); // false // logical not

    Bitwise operators

    The bitwise operators can manipulate binary digits of numbers. For example, the xor
    operator (^) turn on the bits that are set on one side of the operator, but not on both sides.

    $x = 5 & 4; // 101 & 100 = 100 (4) // and
    $x = 5 | 4; // 101 | 100 = 101 (5) // or
    $x = 5 ^ 4; // 101 ^ 100 = 001 (1) // xor (exclusive or)
    $x = 4 << 1; // 100 << 1 =1000 (8) // left shift
    $x = 4 >> 1; // 100 >> 1 = 10 (2) // right shift
    $x = ~4; // ~00000100 = 11111011 (-5) // invert

    These bitwise operators have shorthand assignment operators, just like the
    arithmetic operators.

    $x=5; $x &= 4; // 101 & 100 = 100 (4) // and
    $x=5; $x |= 4; // 101 | 100 = 101 (5) // or
    $x=5; $x ^= 4; // 101 ^ 100 = 001 (1) // xor
    $x=5; $x <<= 1; // 101 << 1 =1010 (10)// left shift
    $x=5; $x >>= 1; // 101 >> 1 = 10 (2) // right shift

    Operator precedence

    In PHP, expressions are normally evaluated from left to right. However, when an
    expression contains multiple operators, the precedence of those operators decides the
    order in which they are evaluated.
    Pre Operator
    1 ++ −−
    2 ~ − (unary)
    3 !
    4 * / %
    5 + − (binary)
    6 << >>
    7 < <= > >= <>
    8 == != === !==
    9 &10 ^
    11 |
    12 &&
    13 ||
    14 = op=
    15 and
    16 xor
    17 or

    For example, logical and (&&) binds weaker than relational operators, which in turn
    bind weaker than arithmetic operators.

    $x = 2+3 > 1*4 && 5/5 == 1; // true

    To make things clearer, parentheses can be used to specify which part of the
    expression will be evaluated first. Parentheses have the highest precedence of all
    operators.

    $x = ((2+3) > (1*4)) && ((5/5) == 1); // true

    Additional logical operators

    In the precedence table make special note of the last three operators: and, or and xor.
    The and and or operators work in the same way as the logical && and || operators. The
    only difference is their lower level of precedence.

    // Same as: $a = (true && false);
    $a = true && false; // $a is false
    // Same as: ($a = true) and false;
    $a = true and false; // $a is true

    The xor operator is a Boolean version of the bitwise ^ operator. It evaluates to true
    if only one of the operands are true.

    $a = (true xor true); // false

    Chapter 4: String

    A string is a series of characters that can be stored in a variable. In PHP, strings are
    typically delimited by single quotes.
    $a = 'Hello';

    String concatenation

    PHP has two string operators. The dot symbol is known as the concatenation operator
    (.) and combines two strings into one. It also has an accompanying assignment operator
    (.=), which appends the right-hand string to the left-hand string variable.
    $b = $a . ' World'; // Hello World
    $a .= ' World'; // Hello World

    Delimiting strings

    PHP strings can be delimited in four different ways. There are two single-line notations:
    double-quote (" ") and single-quote (' '). The difference between them is that variables
    are not parsed in single-quoted strings whereas they are parsed in double-quoted strings.
    $c = 'World';
    echo "Hello $c"; // "Hello World"
    echo 'Hello $c'; // "Hello $c"
    Single-quoted strings tend to be preferred unless parsing is desired, mainly because
    string parsing has a very small performance overhead. However, double-quoted strings
    are considered easier to read, which makes the choice more a matter of preference.
    In addition to single-quoted and double-quoted strings, there are two multi-line
    notations: heredoc and nowdoc. These notations are mainly used to include larger
    blocks of text.

    Heredoc strings

    The heredoc syntax consists of the <<< operator followed by an identifier and a new line.
    The string is then included followed by a new line containing the identifier in order to
    close the string. Variables are parsed inside of a heredoc string, just as with double-quoted
    strings.
    $s = <<<LABEL
    Heredoc (with parsing)
    LABEL;
    Nowdoc strings
    The syntax for the nowdoc string is the same as for the heredoc string, except that the
    initial identifier is enclosed in single-quotes. Variables will not be parsed inside
    a nowdoc string.
    $s = <<<'LABEL'
    Nowdoc (without parsing)
    LABEL;
    Escape characters
    Escape characters are used to write special characters, such as backslashes or
    double-quotes. A table of the escape characters available in PHP can be seen below.

    Character Meaning
    \n    newline
    \t     horizontal tab
    \r    carriage return
    \f     form feed
    \$    dollar sign
    \v    vertical tab
    \'     single quote
    \e    escape
    \"    double quote
    \\    backslash

    For example, line breaks are represented with the escape character “\n” in text.
    $s = "Hello\nWorld";
    Note that this character is different from the
    HTML tag, which creates line
    breaks on web pages.
    echo "Hello
    World";

    When using the single-quote or nowdoc delimiter the only escape characters that
    work are the backslash (\\) and single-quote (\') characters.
    $s = 'It\'s'; // "It's"
    Escaping the backslash is only necessary before a single-quote or at the end of
    the string.
    Character reference
    Characters within strings can be referenced by specifying the index of the desired
    character in square brackets after the string variable, starting with zero. This can be used
    both for accessing and modifying single characters.
    $s = 'Hello';
    $s[0] = 'J';
    echo $s; // "Jello"
    The strlen function retrieves the length of the string argument. This can for example
    be used to change the last character of a string.
    $s[strlen($s)-1] = 'y';
    echo $s; // "Jelly"
    String compare
    The way to compare two strings is simply by using the equal to operator. This will not
    compare the memory addresses, as in some other languages.
    $a = 'test';
    $b = 'test';
    $c = ($a == $b); // true

    — более популярный, специалистов больше.
    — есть много наработок, готового кода и т.д.
    — разработка быстрее, но менее гибкая.
    CodeIgniter:
    — это микрофреймворк, по этому есть большая гибкость в разработке.
    — по той же причине разработка дольше, хотя если сайт не сложный Вы этого не почувствуете.
    — после возрождения CodeIgniter очень быстро развивается (по крайней мере так говорят).

    include vs. require

    در صورت عدم وجود فایل مورد نظر برای فراخوانی:

    فرمان include فقط یک warning می‌دهد و بقیه کد‌ها را می‌خواند اما فرمان require یک error می‌دهد و آن صفحه موقف می‌شود.

    Constructor (مفهوم سازنده)

    در php متد سازنده یک کلاس با نام _construct مشخص می‌شود. اغلب برنامه نویسان از این متد برای عملیاتی همانند مقدار دهی اولیه خاصیت‌های شی استفاده می‌کنند. درصورتی که در یک کلاس متد سازنده تعریف شده باشد به هنگام ایجاد یک شی از کلاس،متد سازنده آن به طور خود کار فراخوانی خواهد شد.یک متد سازنده می‌تواند آرگومانهایی را نیز دریافت کند و براساس آن عملیات مقدار دهی اولیه را انجام دهد.

    سازنده نوع به خصوصی از یک متد در کلاس می‌باشد و زمانی که نمونه‌ای از کلاس ایجاد شود، به صورت خودکار فراخوانی می‌گردد. سازنده برای مقدار دهی اولیه شی و تخصیص حافظه به یک کلاس مورد استفاده قرار می‌گیرد. زمانی که نمونه یا شیئ‌ای از کلاس ایجاد شود، فیلدهای خصوصی(Private) کلاس نیز مقداردهی اولیه می‌شوند. وقتی که ما سازنده را برای کلاس ایجاد نکنیم، کامپایلر به صورت اتوماتیک، یک سازنده پیش فرض برای کلاس ایجاد می‌کند. نام سازنده همیشه هم نام کلاس است.

    مفهوم سازنده (Constructor)

    انواع سازنده‌ها
    -سازنده پیش فرض(Default)
    -سازنده پارامتردهی شده (Parameterized)
    -سازنده ایستا(Static)
    -سازنده خصوصی (Private)
    سازنده پیش فرض(Default)
    به سازنده‌ای می‌گویند که هیچ نوع پارامتری برای آن تعریف نشده باشد به عبارت دیگر بدون پارامتر است. این سازنده مقادیر مشابه در هر نمونه(instance) از کلاس را مقدار دهی می‌کند.
    سازنده پارامتردهی شده (Parameterized)
    سازنده‌ای است که حداقل یک پارامتر دارد. با استفاده از این نوع سازنده می‌توانیم هر نمونه از کلاس را با مقادیر متفاوت مقدار دهی کنیم.
    سازنده ایستا(Static)
    سازنده استاتیک برای مقدار دهی هر نوع داده استاتیک از کلاس یا انجام هر عملی(متد) که باید یک بار اجرا شود، مورد استفاده قرار می‌گیرد. سازنده استاتیک به صورت خودکار و قبل از اولین نمونه سازی از کلاس یا هر داده استاتیک فراخوانی می‌شود. این سازنده یک بار برای هر تعداد نمونه کلاس ایجاد می‌شود.

    نکات کلیدی سازنده استاتیک
    تنها یک سازنده استاتیک می‌تواند در کلاس ایجاد شود.
    سازنده استاتیک هیچ نوع پارامتری نمی‌گیرد زیرا به طور خودکار توسط CLR یا access modifier فراخوانی می‌شود.
    این سازنده به طور خودکار و قبل از اینکه اولین نمونه کلاس ایجاد شود فراخوانی می‌شود.
    نمی توان سازنده استاتیک را به طور مستقیم فراخوانی کرد.
    چه زمانی از سازنده استاتیک استفاده می‌شود؟
    سازنده استاتیک زمانی که کلاس‌های wrapper را برای کدهای مدیریت نشده ایجاد می‌کنید مورد استفاده قرار می‌گیرد. همچنین می‌توانید آن را زمانی که از فایل Log استفاده می‌کنید مورد استفاده قرار دهید و سازنده برای نوشتن ورودی‌ها بکار گرفته شود.
    سازنده خصوصی (Private)
    سازنده Private یک سازنده به خصوص است که به طور کلی در کلاسی مورد استفاده قرا می‌گیرد که فقط شامل تنها اعضای استاتیک باشد. اگر کلاسی فقط سازنده خصوصی داشته و هیچ نوع سازنده عمومی نداشته باشد در این حالت، امکان ایجاد نمونه جدید از کلاس وجود ندارد. در واقع private constructor از ایجاد نمونه سازی کلاس جلوگیری می‌کند. اما اگر بخواهید یک نمونه از کلاسی ایجاد کنید که سازنده خصوصی دارد، باید یک سازنده عمومی همراه با سازنده خصوصی ایجاد کنید.

    In Memory Data Management and Analysis

    Thanks for your reply but I'm still having this issue. :exclamation:
    It is intended to display on one page five languages simultaneously in the view.

    :idea: for example "$request->setLocale('ru')". This command only works in the control.

    We need to run this command or same code in the view for switch languages concurrently.
    контрабандный

    To display different currency, it is predesignated to be used in the view as the third parameter to the lang() method, but we want to return the string by the language key in many languages.

    For example, similar to the currency as the third parameter:
