Description
array
array_intersect_uassoc ( array array1, array array2 [, array ..., callback key_compare_func] )
array_intersect_uassoc() returns an array
containing all the values of array1
that are present in all the arguments. Note that the keys are used in
the comparison unlike in array_intersect().
The index comparison is done by a user supplied callback function.
It 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.
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"));
?>
