Which brings us back to my original argument that the function isn't being
used properly. I was just wrong about how it was being used improperly.
array_search() returns NULL when there is no match.
$result = array_search($findme[$i], $fruit);
if (!is_null($result))
{
print "Key ($result) was found for value $findme[$i]<br>";
}
else
{
print "No match for $findme[$i]<br>";
}
So there we go. There is no bug we just have to learn to read that's all.
*LOL* ;-)
