There are no array operations for the not-that-common things you want to do. You'll need to take the scenic route, as did jgt, if you don't play tricks.
If you just need an array to hold the result, slip in a pair of parentheses, and there you are:

array_intersect_ukey
ARRAY_INTERSECT_UKEY(3) 1 ARRAY_INTERSECT_UKEY(3)array_intersect_ukey - Computes the intersection of arrays using a callback function on the keys for comparisonSYNOPSIS
array array_intersect_ukey (array $array1, array $array2, [array $...], callable $key_compare_func)
DESCRIPTION array_intersect_ukey(3) returns an array containing all the values of $array1 which have matching keys that are present in all the argu-
ments.
PARAMETERS
o $array1
- Initial array for comparison of the arrays.
o $array2
- First array to compare keys against.
o $...
- Variable list of array arguments to compare keys against.
o $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.
int callback (mixed $a, mixed $b)
RETURN VALUES
Returns the values of $array1 whose keys exist in all the arguments.
EXAMPLES
Example #1
array_intersect_ukey(3) example
<?php
function key_compare_func($key1, $key2)
{
if ($key1 == $key2)
return 0;
else if ($key1 > $key2)
return 1;
else
return -1;
}
$array1 = array('blue' => 1, 'red' => 2, 'green' => 3, 'purple' => 4);
$array2 = array('green' => 5, 'blue' => 6, 'yellow' => 7, 'cyan' => 8);
var_dump(array_intersect_ukey($array1, $array2, 'key_compare_func'));
?>
The above example will output:
array(2) {
["blue"]=>
int(1)
["green"]=>
int(3)
}
In our example you see that only the keys 'blue' and 'green' are present in both arrays and thus returned. Also notice that the values for
the keys 'blue' and 'green' differ between the two arrays. A match still occurs because only the keys are checked. The values returned are
those of $array1.
