array_uintersect_uassoc — Computes the intersection of arrays with additional index check, compares data and indexes by separate callback functions
$array1,...$arrays,$value_compare_func,$key_compare_funcComputes the intersection of arrays with additional index check, compares data and indexes by separate callback functions.
array1The first array.
arraysFurther arrays.
value_compare_funcThe 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.
key_compare_funcKey comparison callback function.
Returns an array containing all the values of
array1 that are present in all the arguments.
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
)
