Creating an Array with the array() Function in PHP

Creating an array in PHP using the array() function.

Explanation: This creates an array. For more information about arrays, refer to the array section.

Parameter description: The syntax is "index => values", separated by commas. Indices can be strings or numbers. If omitted, integer indices start from 0. If an index is integer, the next generated index will be the current maximum integer index plus one. Duplicate indices cause later values to overwrite earlier ones.

Trailing commas after the last array element are legal, though uncommon.

Return value: Returns an array built from the given parameters. Indices can be supplied using the => operator.

Example:

<?php
$fruits = array(
    "fruits" => array(
        "a" => "orange",
        "b" => "banana",
        "c" => "apple"
    ),
    "numbers" => array(1, 2, 3, 4, 5, 6),
    "holes" => array(
        "first" => 0,
        "second" => 5,
        "third" => 6
    )
);
?>

Output:

Array
[
    fruits] => Array
        [
            a] => orange
            b] => banana
            c] => apple
        ]
    [numbers] => Array
        [
            0] => 1
            1] => 2
            2] => 3
            3] => 4
            4] => 5
            5] => 6
        ]
    [holes] => Array
        [
            0] => first
            5] => second
            6] => third
        ]
