+**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
+<code>
