I downwload the latest version of PHP (PHP w/ the Zend Engine 2) and try to play with it !

The problem comes when I use the XTemplate class. I got a warning like "Illegal offset ..." and then the Apache (1.3.20) core dump.

The same development work perfectly with the PHP 4.2.2.

I you need more details let me know to send you the source code.

Best Regards,
Ali Barimani.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

The Apache server core dump when we try to use the XTemplate class with the following message before exiting:

"Warning: Illegal offset type in class.XTemplate.php on line 189"

A dbx on the core file gives:

The real version used is 4.3.0-dev. Dowloaded from php.net web site.
 [2002-10-17 22:51 UTC] iliaa@php.net
Please try using this CVS snapshot:

  http://snaps.php.net/php4-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-latest.zip

If the bug still occures, make sure that when you compile PHP with --enable-debug, so that the backtrace shows meaningful information.
 [2002-10-24 03:52 UTC] alibarim at yahoo dot com
The link http://snaps.php.net/php4-latest.tar.gz does not exit !
 [2002-10-24 03:57 UTC] derick@php.net
It really does exist. I just downloaded it. Please try again.

I download the 4.3.0pre1 from the official PHP site.
This version seems to be stable an working correctly.

But it does'nt include the Zend Engine 2 !
How can I build with the new Engine ?

Regards.
 [2002-10-24 15:47 UTC] iliaa@php.net
Zend Engine you need to download seperately as the 4.3.0 comes with ZE1. ZE2 can be downloaded from the CVS.
