array_intersect_assoc

array_intersect_assoc

Computes the intersection of arrays with additional index check

array **array_intersect_assoc** array $array array $arrays

returns an array

containing all the values of that are present in all the arguments. Note that the keys are also used in the comparison unlike in . array_intersect_assoc``array``array_intersect

arrayThe array with master values to check.

arraysArrays to compare values against.

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

Voorbeeld: example

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

Array
(
    [a] => green
)

In our example you see that only the pair is present in both arrays and thus is returned. The value is not returned because in its key is while the key of "red" in is , and the key is not returned because its values are different in each array. "a" => "green"``"red"``$array1``0``$array2``1``"b"

The two values from the pairs are considered equal only if . In other words a strict type check is executed so the string representation must be the same.

key => value``(string) $elem1 === (string) $elem2
