SYNOPSIS
array array_uintersect_assoc (array $array1, array $array2, [array $...], callable $value_compare_func)
DESCRIPTION
Computes the intersection of arrays with additional index check, compares data by a callback function.
Note that the keys are used in the comparison unlike in array_uintersect(3). The data is compared by using a callback function.
PARAMETERS
o $array1
- The first array.
o $array2
- The second array.
o $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.
int callback (mixed $a, mixed $b)
RETURN VALUES
Returns an array containing all the values of $array1 that are present in all the arguments.
EXAMPLES
Example #1
array_uintersect_assoc(3) example
<?php
$array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
$array2 = array("a" => "GREEN", "B" => "brown", "yellow", "red");
print_r(array_uintersect_assoc($array1, $array2, "strcasecmp"));
?>
The above example will output:
Array
(
[a] => green
)
