Description:
------------
Previos bersion what I have used was 1.1, which seems to work.
But an upgrade to 2.1.2 result in a memory leak.

[root@lab022 new]# php final.php | m

Here is my little testcase.
The open and close handler is the same like in the Readme file.

require_once 'RALparser.php';
require_once 'XML/XML_HTMLSax.php';

$handler =& new RALparser();
$parser =& new XML_HTMLSax();

$parser->set_object($handler);
$parser->set_option('XML_OPTION_CASE_FOLDING',false);
$parser->set_element_handler('openHandler', 'closeHandler');

$htmlCode = file_get_contents( 'out.html');
$parser->parse($htmlCode);

print_r($handler_return);

I can't do an upgrade on an newer version of php which would cause a too long downtime of the server.

What do you mean with 'm' tool?

[2004-06-04 08:00 UTC] sonny at sun dot com

I have changed the code in the constructor but it have the same behavior. Maybe it's one of my codes/scripts which will cause this memory leak. The 'm' tool is just 'more' not more ;-).

I have uploaded my scripts where you can take a look on it.
RALparser.php - http://dj.laxly.de/php/ral/RALparser.phps
final.php - http://dj.laxly.de/php/ral/final.phps
out3.html - http://dj.laxly.de/php/ral/out3.html
complete package: http://dj.laxly.de/php/ral/ral-tar

Maybe you can reconstruct it with my scripts. Or does i have an strange php config which cause the memory leaks.

No we're still running on 1.3.26.
In case of php I don't wanna use Apache 2.x.
The Multithreading seems not to work very well with php.

Bummer not to reproduce this.
But thanks for you coding hints.

I'm not very amused about the leak but I it's does not gone there is nothing I can do.
Might be in several constelation of funtions because this memory leak I have seen as well with phpDocumentor.

So I'd like to thank you for your support.
