I'm assuming that the deployment/install script was put at /usr/local/packager/packager.py when it was installed. Apparently, you can use this script to list the packages that are installed:
/usr/local/packager/packager.py list
Unfortunately, the script that you used to install PHP doesn't appear to have an uninstall feature. However, you should be able to remove the installed content that was installed from /usr/local. It is probably a good idea to examine the contents of the /usr/local directory first to confirm the contents:
ls -al /usr/local
From what I can see, the script is installing the software with prefixes like "php5-*", and is linking to the 'current' version of that software using a symbolic link named "php5". The commands below will unlink the symlink, and remove the installed versions of PHP that were installed using the script mentioned above:
sudo unlink /usr/local/php5
sudo rm -rf /usr/local/php5-*
To remove the supplemental configuration file that was installed with the updated PHP software, you may be able to remove the config file at /etc/apache2/other/+php-osx.conf:
sudo rm -rf /etc/apache2/other/+php-osx.conf
Then restart Apache:
sudo apachectl restart
Note: the /usr/local folder shouldn't have much inside of it unless you've installed 3rd party software there. You may find a few PHP installs there that have names like "php5-5.3.x...", "php5-5.4.x...", and "php5-5.5.x...". The rm command above should remove any variants of this naming scheme. Removing the additional Apache configuration file should allow Apache to start normally after the module has been removed.
