    array — Create an array

    Опис

    array(mixed ...$values): array

    Creates an array. Read the section on the array type for more information on what an array is, including details about the alternative bracket syntax ([]).

    values

    Syntax "index => values", separated by commas, define index and values. index may be of type string or integer. When index is omitted, an integer index is automatically generated, starting at 0. If index is an integer, next generated index will be the biggest integer index + 1. Note that when two identical indices are defined, the last overwrites the first.

    Having a trailing comma after the last defined array entry, while unusual, is a valid syntax.

    Returns an array of the parameters. The parameters can be given an index with the => operator. Read the section on the array type for more information on what an array is.

    Приклади

    The following example demonstrates how to create a two-dimensional array, how to specify keys for associative arrays, and how to skip-and-continue numeric indices in normal arrays.

    Приклад #1 array() example

    <?php
    $fruits     = array (
    "fruits" => array("a" => "orange", "b" => "banana", "c" => "apple"),
    "numbers" => array(1, 2, 3, 4, 5, 6),
    "holes" => array("first", 5 => "second", "third")
    );
    ?>

    Приклад #2 Automatic index with array()

    <?php
    $array     = array(1, 1, 1, 1, 1, 8 => 1, 4 => 1, 19, 3 => 13);
    print_r($array);
    ?>

    Поданий вище приклад виведе:

    Array
(
    [0] => 1
    [1] => 1
    [2] => 1
    [3] => 13
    [4] => 1
    [8] => 1
    [9] => 19
)

    Note that index '3' is defined twice, and keep its final value of 13. Index 4 is defined after index 8, and next generated index (value 19) is 9, since biggest index was 8.

    This example creates a 1-based array.

    Приклад #3 1-based index with array()

    <?php
    $firstquarter     = array(1 => 'January', 'February', 'March');
    print_r($firstquarter);
    ?>

    Поданий вище приклад виведе:

    Array
(
    [1] => January
    [2] => February
    [3] => March
)

    As in Perl, you can access a value from the array inside double quotes. However, with PHP you'll need to enclose your array between curly braces.

    Приклад #4 Accessing an array inside double quotes

    <?php

    $foo     = array('bar' => 'baz');
    echo     "Hello {$foo['bar']}!"; // Hello baz!

    ?>

    Примітки

    Зауваження:

    array() is a language construct used to represent literal arrays, and not a regular function.

    As of PHP 5.4.x you can now use 'short syntax arrays' which eliminates the need of this function.

    Example #1 'short syntax array'
    <?php
    $a     = [1, 2, 3, 4];
    print_r($a);
    ?>

    The above example will output:
    Array
    (
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    )

    Example #2 'short syntax associative array'
    <?php
    $a     = ['one' => 1, 'two' => 2, 'three' => 3, 'four' => 4];
    print_r($a);
    ?>

    The above example will output:
    Array
    (
    [one] => 1
    [two] => 2
    [three] => 3
    [four] => 4
    )
