Yea, I would think not. In fact, I started testing this and I am getting a very strange result. Here is the link that I downloaded: http://www.xdebug.org/files/php_xdebug-2.1.0-5.3-vc9-nts-x86_64.dll Here it is in the directory: Directory of C:\PHP\ext 08/03/2010 10:49 AM <DIR> . 08/03/2010 10:49 AM <DIR> .. 08/03/2010 10:49 AM <DIR> CVS ...... 08/03/2010 10:49 AM 152,576 php_xdebug-2.0.5-5.3-vc9-nts.dll 08/03/2010 08:39 AM 169,984 php_xdebug-2.1.0-5.3-vc9-nts-x86_64.dll 08/03/2010 10:46 AM 140,800 php_xdebug-2.1.0-5.3-vc9-nts.dll 03/03/2010 09:52 PM 62,976 php_xmlrpc.dll Here is in my php.ini file: [xdebug] zend_extension="c:/php/ext/ php_xdebug-2.1.0-5.3-vc9-nts-x86_64.dll" xdebug.remote_enable=1 xdebug.remote_host=127.0.0.1 xdebug.remote_port=9100 xdebug.remote_handler=dbgp xdebug.profiler_enable=1 xdebug.profiler_output_name=cachegrind.out.%s xdebug.profiler_output_dir=c:\xdebug_prof And in my phpinfo() XDebug xdebug support enabled Version 2.1.0-dev So, I THOUGHT I was working...it was not. Somehow, PHP was picking up this file instead: php_xdebug-2.0.5-5.3-vc9-nts.dll Now, how the heck is that happening? How is it grabbing a file than the one I'm specifiying? So, I took all but the x63 version out and you are correct, it won't load. So, I put ONLY the 32 bit version of the new download (php_xdebug-2.1.0-5.3-vc9-nts.dll) and guess what? It WON'T load either!! Good grief. So, I reverted back to the old file and it's working. I can't ge the new version to work at all. But I'm more confused as to how PHP is grabbing a different file.

It can't work, maybe you fetched the 32b version. On 3 Aug 2010 16:20, "Keith Davis" <keithdavis@xxxxxxxxxxxxxxx> wrote: I don't need performance, but I need it to not take 5x longer to load. I work too darn fast for this thing. I can debug most things procedurally much faster. So, I only use the debugger when I can't do it with my own debug code. I'm not using the x64 version of PHP, just the x64 version of XDebug. I did that without thinking. Strangely enough, it works.
