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";
}
