php dynamic array intersect - repost

Hi, I have some dynamically generated arrays $resultfull = $db2->fetchAll(); ${'unique_tags'.$unique_tags0_key}=Array(); foreach ($resultfull as $values2) { list($tagname,$id)=$values2; array_push(${'unique_tags'.$unique_tags0_key}, $id); } $unique_tags0_key=$unique_tags0_key+1; } and i want to intersect them. I want to use string as arguments in php array intersect function $result00=array_intersect($unique_tags0, $unique_tags1); i want to replace the above with something like $one="$unique_tags0, $unique_tags1, $unique_tags2 ....."; $result00=array_intersect($one); $one is string but dynamically has the names of existing arrays. The number of the arrays i want to intersect is not known, so i want to use dynamically generated string as argument, if this is possible. 5$ should be ok for helping me on this. I m waiting for replies PS, Please bid if you have done it before.
