[thelist] PHP - str_replace problem

[Chris Ditty]

Hi all.  I'm trying to do a little code snippets page for a site I am
working on.  I figured it would be simple enough.  I would do a
str_replace and replace the various html codes with the ascii
eqivulant.  Unfortunately, it is not working as expected.  Can anyone
help with this?

This is what I am using.
$snippetCode = str_replace("\n", "<br>", $snippet['snippetCode']);
$snippetCode = str_replace("<", "&gt;", $snippetCode);
$snippetCode = str_replace(">", "&lt;", $snippetCode);
$snippetCode = str_replace("&", "&amp;", $snippetCode);

This is what is in $snippet['snippetCode'].
?><pre><? print_r($ArrayName); ?></pre><?

This is what is showing on the web page.
?&lt;&gt;pre&lt;&gt;? print_r($ArrayName); ?&lt;&gt;/pre&lt;&gt;?

If anyone can help, it would be appreciated.  Also, if you have a
quick and dirty code colorer, I would appreciate that.

Thanks
Chris
