    Alright I am trying to get this highlight_string function to work without any luck at all. Here is my code without the highlight_string in there.

    
{	
$output .= "
<hr>
<div class='grey_top'></div>
<div class='grey'>
<a href='$row->website'>$row->name</a> says:<br><br>
$row->comment
</div>
";
}
echo $output;
    PHP:
    This is the page I am trying to get work.

    http://www.phpelf.com/echo.php

    Basically you can post a comment and I would expect php code to be in that comment. Now when I return it I would like just the comment portion to be highlighted.

    Any ideas?

    Here is some code, perhaps you need to make sure you input a <?php ?> where you want php code to be highlighted. 

    <?php
$comment="Here is a comment about stuff ha ha ha. Oh some php code sounds like fun. <?php echo 'some stuff about something in php'; ?> ";
highlight_string ($comment);
?>
    PHP:
    the code above takes the comment and just highlights the part contained in the <?php ?> tags.

    Well it displays properly when I have it out of the while. But when I put it in it dont work for some reason.

    Works like this..

    				
while ( $row = mysql_fetch_object($result) )
{	
$string_comment = $row->comment;
echo "
<br><div class='grey_top'></div>
<div class='grey'>
<a href='$row->website'>$row->name</a> says:<hr><br>
</div>";
}
	
highlight_string($string_comment);
    PHP:
    But dont work when I put that line inside the While.

    I got it. Just had to break the echo and then do the highlight then start the echo back up.

    
while ( $row = mysql_fetch_object($result) )
{	
$string_comment = $row->comment;
echo "
<br><div class='grey_top'></div>
<div class='grey'>
<a href='$row->website'>$row->name</a> says:<hr><br>";
highlight_string($string_comment);
echo "</div>";
}
    PHP:
    That only killed an hour. :)

    I know what you mean, seems like the smallest problems take up a lot of time. I tend to just take a break from coding for an hour or so when i cant seem to wrap my head around a problem i cant find. Works wonders i usually fix it in 10 seconds when i come back.
