 +**PHP to secure a setup, a good start is a secure php.ini, for example:** 
 +   * disable the Fopen Wrapper, **allow_url_fopen** = Off 
 +   * use disable_classes and disable_functions like: - ini_alter, ini_get_all, ini_get, ini_restore, ini_set, php_get_tmpdir, php_ini_scanned_files, php_logo_guid, php_uname, phpcredits, phpinfo, phpversion, putenv, restore_include_path, set_include_path, set_time_limit, version_compare, zend_logo_guid, zend_version, show_source, system, shell_exec, passthru, exec, proc_open, time_limit, version_compare, zend_logo_guid, zend_version, show_source, system, shell_exec, passthru, exec, proc_open etc. etc. 
 +   * set **register_globals = off** 
 +   * set log_errors = on, error_reporting and error_log 
 +   * use **open_basedir** and include_path 
 +   * use **safe_mode** if possible
