Xdebug

These are instructions for installing Xdebug. Please also refer to http://xdebug.org/support.php for support.

You need to compile Xdebug separately from the rest of PHP. Note, however, that you need access to the scripts phpize and php-config. If your system does not have phpize and php-config, you will need to compile and install PHP from a source tarball first, as these script are by-products of the PHP compilation and installation processes. It is important that the source version matches the installed version as there are slight, but important, differences between PHP versions.

Once you have access to phpize and php-config, do the following:

1. Unpack the tarball: tar -xzf xdebug-2.2.x.tgz. Note that you do not need to unpack the tarball inside the PHP source code tree. Xdebug is compiled separately, all by itself, as stated above.
2. cd xdebug-2.2.x
3. Run phpize: phpize (or /path/to/phpize if phpize is not in your path).
4. ./configure --enable-xdebug (or: ../configure --enable-xdebug --with-php-config=/path/to/php-config if php-config is not in your path)
5. Run: make
6. cp modules/xdebug.so /to/wherever/you/want/it
7. add the following line to php.ini: zend_extension="/wherever/you/put/it/xdebug.so"
8. Restart your webserver.
9. 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!
