array_intersect_uassoc
(PHP 5, PHP 7, PHP 8)
array_intersect_uassoc — Computes the intersection of arrays with additional index check, compares indexes by a callback function
Description
array_intersect_uassoc() returns an array
containing all the values of array
that are present in all the arguments. Note that the keys are used in
the comparison unlike in array_intersect().
Parameters
-
array -
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.
Return Values
Returns the values of array whose values exist
in all of the arguments.
Examples
Example #1 array_intersect_uassoc() example
<?php
$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"));
?>
The above example will output:
Array
(
[b] => brown
)
