Re: [PHP] Help with matchng strings
array_intersect() will give you listC directly. Just feed it list A and B. Then you can take a copy of listA and do a foreach on the array_keys() of listC and unset() them. Now this copy with the removed elements becomes your listD -Rasmus On Sun, 25 Aug 2002 [EMAIL PROTECTED] wrote: I have two list one is listA and the other is listB I would like to take the values in listB and compare them with listA if any of them match then I what to create a new list listC and put the values that match in it.

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: $valueAbr\n;
}
echo br;
foreach($arraylistB as $valueB){
echo ValueB: $valueBbr\n;
}
echo br;
foreach($result as $valueC){
echo ValueC: $valueCbr\n;
}
