    array_uintersect_uassoc

    (PHP 5, PHP 7)

    array_uintersect_uassoc — Computes the intersection of arrays with additional index check, compares data and indexes by separate callback functions

    Description

    array array_uintersect_uassoc ( array $array1 , array $array2 [, array $... ], callable $value_compare_func , callable $key_compare_func )

    Computes the intersection of arrays with additional index check, compares data and indexes by separate callback functions.

    Parameters

    array1

    The first array.

    array2

    The second array.

    value_compare_func

    The comparison function must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

    int callback ( mixed $a, mixed $b )
    key_compare_func

    Key comparison callback function.

    Return Values

    Returns an array containing all the values of array1 that are present in all the arguments.

    Examples

    Example #1 array_uintersect_uassoc() example

    <?php
    $array1     = array("a" => "green", "b" => "brown", "c" => "blue", "red");
    $array2 = array("a" => "GREEN", "B" => "brown", "yellow", "red");

    print_r(array_uintersect_uassoc($array1, $array2, "strcasecmp", "strcasecmp"));
    ?>

    The above example will output:

    Array
(
    [a] => green
    [b] => brown
)

    Please note, the correct function synopsis is:

    array array_uintersect_uassoc ( array array1, array array2 [, array ...], callback data_compare_func, callback key_compare_func)

    You may specifiy as many arrays as you like, but the last two parameters must be valid call back functions.
