array_intersect_uassoc — Computes the intersection of arrays with additional index check, compares indexes by a callback function
Parametersarray
Initial array for comparison of the arrays.
arrays
Arrays to compare keys against.
key_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.
CautionReturning non-integer values from the comparison function, such as float, will result in an internal cast to int of the callback's return value. So values such as 0.99 and 0.1 will both be cast to an integer value of 0, which will compare such values as equal.
Returns the values of array whose values exist in all of the arguments.

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