I have a quiz where the ansers are held in a array called $correct answers. When I compare the string if ($_REQUEST['x']= $correct_answers[$page-1]) { with a double == the answer is always correct with the single = it is always wrong.
A single "=" it's an assignment, not a comparison; and though it sometimes work, you shouldn't compare strings with "==", but using string functions, such as strcmp()... or similar_text(), etc.
when I echo out the posted answer and the value from the answers arrray they are correct.
echo "post equals".$_POST['x']."     corect answer is".$correct_answers[$page-1];
