Installing xdebug with PHP 5.5

for xampp server first download xdebug and insert into php extention and edit php.ini file like this:

    [XDebug]
; Only Zend OR (!) XDebug
; XAMPP and XAMPP Lite 1.7.0 and later come with a bundled xdebug at     C:\xampp/php/ext/php_xdebug-2.3.1-5.5-vc11.dll, without a version number.
xdebug.remote_enable=1
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
; Port number must match debugger port number in NetBeans IDE Tools > Options > PHP
xdebug.remote_handler=dbgp
xdebug.profiler_enable=1
xdebug.profiler_output_dir="C:\xampp\tmp"
[PHP_XDEBUG-2.3.1-5.5-VC11]
zend_extension="C:\xampp\php\ext\php_xdebug-2.3.1-5.5-vc11.dll"

Since this seems to bother more and more people trying to install xdebug via pecl here are the options:

• Windows: Get the binary
• Ubuntu (>12.04): sudo apt-get install php5-xdebug
• Linux (other): via package manager or compile the latest source

Using PECL to install X-Debug for PHP5.5 as @Slayer Birden also answered will not work up to now and I don't think it will change in the near future.

Ok so I've stumbled upon this myself.

First of all, the 20090626 lib is compiled for php 5.3. So you can't really use that. Here are the steps I've performed in order to be able to use xdebug with php 5.5:

1. Download the source via xdebug download page.
2. Follow this guide for compiling your source into lib.
3. So now the extension is in correct source folder: 20121212, and you need to enable xdebug in your config.

4. I'm on ubuntu 12.04, so next steps might not work with your system:

   • create 20-xdebug.ini config and copy it to both /etc/php5/apache/conf.d and /etc/php5/cli/conf.d folders (if you plan on using xdebug in your cli of course). Insert next line of code there: zend_extension=xdebug.so
   • enable xdebug in both apache2 and cli php.ini configuration files:

     xdebug.remote_enable = 1
     xdebug.renite_enable = 1
     xdebug.max_nesting_level = 1000
     xdebug.profiler_enable_trigger = 1
     xdebug.profiler_output_dir = '/var/log'

I had a similar problem on Ubuntu 14.10. I forgot to enable xdebug: sudo php5enmod xdebug after installing xdebug from repository: sudo apt-get install php5-xdebug Also do not forget to restart web server sudo service apache2 restart

My xdebug.ini looks like this: zend_extension=xdebug.so xdebug.remote_enable = 1
