PHP open_basedir Protection
PHP's open_basedir protection prevents users from opening files outside of their home directory with php.

This security tweak uses Apache DSO style directives. If PHP is configured to run as a CGI, SuPHP or
FastCGI process, the open_basedir setting must be manually specified in the relevant php.ini file.
See the EasyApache documentation for more information.
