                             array_intersect_assoc

   (PHP 4 >= 4.3.0)
   array_intersect_assoc -- Computes the intersection of arrays with
   additional index check

Description

   array array_intersect_assoc ( array array1, array array2 [, array
   ...])

   array_intersect_assoc() 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().

   Example 1. array_intersect_assoc() example
   <?php
   $array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
   $array2 = array("a" => "green", "yellow", "red");
   $result_array = array_intersect_assoc($array1, $array2);
   ?>

   $result_array will look like:
Array
(
    [a] => green
)

   In our example you see that only the pair "a" => "green" is present in
   both arrays and thus is returned. The value "red" is not returned
   because in $array1 it's key is 0 while the key of "red" in $array2 is
   1.

   The two values from the key => value pairs are considered equal only
   if (string) $elem1 === (string) $elem2 . In otherwords a strict type
   check is executed so the string representation must be the same.

   See also array_intersect(), array_diff() and array_diff_assoc().
