if you dont want to get this error simply put a @ at the beginning of the line code, in my example, on line 6

sample code:

PHPCODE
##########################
<?php</p>
<p>// THIS WILL PRODUCE THE ERROR <br>
$a = 7;<br>
$b = 0;</p>
<p> //suppress division-by-zero warning<br>
$c = $a / $b;<br>
?>
##########################

PHPCODE:
##########################
<?php</p>
<p>// THIS WILL RESOLVE THE ERROR <br>
$a = 7;<br>
$b = 0;</p>
<p> //suppress division-by-zero warning<br>
