Using PHP Version 5.2.9-2 on Win 32
For those wondering what happens with numeric keys, here's a short example that might save you
time :
<?php
$a=array(1=>'a',2=>'b',3=>'c');
$b=array(2=>'z',3=>'c',4=>'d');
$c=array_intersect_key($a,$b);
print_r($c);
?>
Will output
Array
(
[2] => b
[3] => c
)
It works fine, if values are different, the first array's ones are retained.
