Re[2]: [PHP] Help with matchng strings

Hello Rasmus, Ok I understand the array_intersect and have gotten that to work. I just don't understand the second part using the foreach and unset(). this is what I have it gives me three separate list $listA="tester1 tester2 tester3 tester4 tester5 tester6 tester7 tester8 tester9"; $listB="tester4 tester6 tester8"; $arraylistA=explode(" ",$listA); $arraylistB=explode(" ",$listB); $result = array_intersect ($arraylistA, $arraylistB); foreach($arraylistA as $valueA){ echo "ValueA: $valueA<br>\n"; } echo "<br>"; foreach($arraylistB as $valueB){ echo "ValueB: $valueB<br>\n"; } echo "<br>"; foreach($result as $valueC){ echo "ValueC: $valueC<br>\n"; } Sunday, August 25, 2002, 4:48:36 PM, you wrote: RL> array_intersect() will give you listC directly.
