Sdebug is a fork of the Offical Xdebug to compilant with Swoole.

• The name of the extension is sdebug instead of xdebug, if you want to use Phpunit CodeCoverage, you have to manually modify xdebug to be sdebug.

You can clone the Sdebug source directory with:

git clone https://github.com/swoole/sdebug.git

Then move into this new directory:

cd sdebug

Although it is recommended to run the latest version from the master branch, older versions are available through tags. For example to checkout the 2.5.5 release, you can switch to it with git checkout XDEBUG_2_5_5.

If PHP is installed in a normal, and uncomplicated way, with default locations and configuration, all you will need to do is to run the following script:

./rebuild.sh

This will run phpize, ./configure, make clean, make and make install.

The long winded way of installation is:

1. Run phpize: phpize (or /path/to/phpize if phpize is not in your path).

2. ./configure --enable-xdebug (or: ../configure --enable-xdebug --with-php-config=/path/to/php-config if php-config is not in your path)

3. Run: make clean

4. Run: make

5. Run: make install

6. Add the following line to php.ini (which you can find by running php --ini, or look at phpinfo() output): zend_extension="xdebug.so".

   Please note, that sometimes the php.ini file is different for the command line and for your web server. Make sure you pick the right one.

7. Unless you exclusively use the command line with PHP, restart your webserver.

8. Write a PHP page that calls phpinfo();. Load it in a browser and look for the info on the Xdebug module. If you see it, you have been successful! Alternatively, you can run php -v on the command line to see that Xdebug is loaded:

     $ php -v
