array_uintersect_uassoc — Computes the intersection of arrays with additional index check, compares data and indexes by a callback functions
$array1
, array $array2
[, array $ ...
], callable $data_compare_func
, callable $key_compare_func
)Computes the intersection of arrays with additional index check, compares data and indexes by a callback functions Note that the keys are used in the comparison unlike in array_uintersect(). Both the data and the indexes are compared by using separate callback functions.
array1
The first array.
array2
The second array.
data_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.
key_compare_func
Key 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
)
