I don't know if anyone here can help, but the company I am working at is using a very old version of PHP for Windows, 5.3.10, 32-bit (and yes, I know, it's a little hard to swallow).

I was able to find a version of Xdebug that should work with this (2.2.7-5.3-vc9, 32-bit), and tried both the TS and the NTS versions, but neither will load with this version of PHP (I pulled the one from dev web server, 5.3.10, 32-bit), but both fail to load (php -m).

First of all, is there a way to determine if the version of PHP we are using is TS or NTS? Secondly, is there a way to determine why Xdebug is failing to load and / or a way to know for certain that I've grabbing the correct version of Xdebug?

I just tried using the complete build here, https://phpdev.toolsforresearch.com/php-5.3.29-nts-Win32-VC9-x86.zip, and that one fails to load as well:

c:\PHP5329>c:\PHP5329\php.exe -m
Failed loading php_xdebug.dll
PHP Warning: PHP Startup: Unable to load dynamic library 'ext\php_xsl.dll' - The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail.

Hi,

For PHP 5.3.10, I don't know, but I still have a PHP 5.3.29 addon for Wampserver that works with the following configuration:
In the php/php5.3.29/zend_ext/ folder there is the file :
php_xdebug-2.2.7-5.3-vc9.dll TS

And, at the end of php.ini file there is :
Code:
; XDEBUG Extension
[xdebug]
zend_extension = "J:/wamp/bin/php/php5.3.29/zend_ext/php_xdebug-2.2.7-5.3-vc9.dll"
xdebug.remote_enable = off
xdebug.profiler_enable = off
xdebug.profiler_enable_trigger = Off
xdebug.profiler_output_name = cachegrind.out.%t.%p
xdebug.profiler_output_dir = "J:/wamp/tmp"
xdebug.show_local_vars=0

You must adapt the paths to your own installation.

It is also necessary that the VC2008 VC9 redistributable packages are installed.

I've tried php_xdebug-2.2.7-5.3-vc9.dll TS (and php_xdebug-2.2.7-5.3-vc9.dll NTS), I'll check the wizard, but I'm pretty sure that is the correct version.

I don't know what I was thinking anyway, the problem is that this machine does not have VC9 installed (and I have no admin rights on this laptop). I was able to get Xdebug to load for PHP 5.5 (because it uses VC11), which may have to be good enough for my development for now (hopefully I can push and get us to 7.4 or 8 soon).

What are the lines in your php.ini that should load php_xdebug.dll?

I was wrong. I get VC9 installed, still does not load. I don't have access to the php.ini file, but the entries are the same for 5.5 as they are for 5.3, and they work for 5.5, but not for 5.3. Regardless, I get php_xdebug.dll failed to load when I do "c:\PHP\php.exe -m".

I already suspected that. I have never seen a (modern) Windows machine without the VC9 redistributable files installed. If those are not present a lot of things will fail.

If you do not have access to the php-ini you do not know where the php_xdebug.dll file has to be present. Remember that the general recommendation is to put the full path in the 'zend_extension=' php.ini statement. Did you try
Code:
zend_extension = "c:/PHP5329/ext/php_xdebug.dll"
with my build, like you tried in https://www.apachelounge.com/viewtopic.php?p=41321#41321 ?

php_xdebug.dll only depends on php5.dll (NTS) or php5ts.dll (TS), USER32.dll, WS2_32.dll, MSVCR90.dll (the VC9 runtime) and KERNEL32.dll. Almost every other PHP 5.3 extension has at least the same dependencies. PHP 5.5's php_xdebug.dll also has the same dependencies except for MSVCR110.dll in stead of MSVCR90.dll.

Please be sure that you do not use extension= to load php_xdebug.dll. The required php.ini statement is zend_extension. If you do not want to use a full path the statement usually is
Code:
zend_extension=ext/php_xdebug.dll
for PHP 5.3 with a partial path. In PHP 5.5 that was changed. Then this statement suffices
Code:
zend_extension=php_xdebug.dll
PHP 5.5+ will look in the directory with the other extensions.

If you cannot edit php.ini: try putting the php_xdebug.dll in the directory with php.exe (as well).

Try
Code:
php -i | find "TS"

It will report either
Code:
Zend Extension Build => API220090626,NTS,VC9
PHP Extension Build => API20090626,NTS,VC9

or
Code:
Zend Extension Build => API220090626,TS,VC9
PHP Extension Build => API20090626,TS,VC9

I did not mean I did not access to the php.ini file at all, I just meant at the time of my posting the other day (I have to work only on a very secure laptop over VPN and I was away from it). Anyway, you gave me the answer, as here was my php.ini:


Code:

[XDebug]
zend_extension=php_xdebug.dll
xdebug.remote_enable=1
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9003
; xdebug.remote_handler=dbgp
xdebug.remote_autostart=1
; xdebug.idekey=vsc
; xdebug.profiler_enable=0
; xdebug.profiler_enable_trigger=0
; xdebug.profiler_output_name=%R.%S.cachegrind
; xdebug.profiler_output_dir=c:\inetpub\temp
xdebug.remote_log=c:\inetpub\temp\xdebug.log


I changed it to

Code:

zend_extension=ext/php_xdebug.dll


Now, it loads! Thanks.[/code]
