Computes the intersection of arrays with additional index check, compares data by a callback function
Syntax
array_uintersect_assoc ( array $array1 , array $array2 [, array $... ], callable $value_compare_func ) : array
Parameters
array1
The first array.
array2
The second array.
value_compare_func
The comparison function must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.
Return
Returns an array containing all the values of array1 that are present in all the arguments.
Examples
array1 array2 value_compare_func
<?
function myfunction($a, $b)
{
if ($a < $b) {
return -1;
} elseif ($a > $b) {
return 1;
} else {
return 0;
}
}
$array1 = array("a" => 0, "b" => 1, "c" => 2, "d" => 3);
$array2 = array("a" => 0, "b" => 4, "e" => 2, "f" => 5);
$value_compare_func = "myfunction";
$return = array_uintersect_assoc($array1, $array2, $value_compare_func);
print_r($return);
?>

[a] => 0
