On RedHat7.1 Box with apache generate a HTML form. 
put a dropdown menu as form element.
ie :
<pre>
<form name="test" action="bug.php" method="POST">
<select name="pop" >
<option value="0">NO</option>
<option value="1">NO</option>
<input type="Submit" name="Submit_Button" value="Send Values">
</pre>

bug.php
<pre>
<?
if($pop){
   echo "There isnt any bug";
 } else {
   echo "Ops!";
}
?>
</pre>


If $pop=0 then engine cant read this value, and print "Ops!"

I did try this on 3 servers that uses RedHat7.1 with PHP Version 4.0.3pl1.
