Assuming you did $move_uploaded_file = move_uploaded_file($filename, $destination);, then isset($move_uploaded_file) will always be true. isset() just checks if the variable you past to it is set, not if it has a non-false value. You could simply use if(move_uploaded_file($filename, $destination)), or if($move_uploaded_file). My apologies - i forgot to include the $move_uploaded_file = move_uploaded_file($filename, $destination); line.

I saw in the manual that isset() "isset --- Determine if a variable is set and is not NULL" and thought if move_uploaded_file() returns false, the error checking will be triggered.But now i see the sample code in the manual and stand corrected. So what was happening that $move_uploaded_file was set but empty.My understanding of isset() was wrong. * *
