Note Submitter: Henry Cesbron Lavau ---- To copy values from an array which contains arrays db 05-Jan-2005 04:06 said : If you copy (=) an array which contains arrays it will be REFERENCED not COPIED. Well, this is only true since PHP 5. Under PHP4, it is COPIED. So be aware of this when porting code from PHP 4 to PHP 5 ! Now, if you want to copy the values (and not the references), (instead of using array_diff as stated below, which won't work either under PHP 5) just use : $a2 = array_combine($a1, $a1);
