Customizing PHP Safe Mode

We’ll guide you through using PHP safe_mode and how-to enable it and to customize it for certain sites on your server. When using PHP as an Apache module, you can also change the configuration settings using directives in Apache configuration files (e.g. httpd.conf) and .htaccess files. PHP safe_mode is very important to in terms of server security because it restricts and disables the dangerous functions in PHP from the scripts like PHP Shell that can otherwise cause damages to your server and client sites.
It is very simple to active safe mode on the entire server. All you need to do is just edit the php.ini file. If you can’t find where php.ini is or have multiple copies on your server the best thing to do is run phpinfo() to find it. Open up Notepad or your favorite HTML editor and paste in the following from this file.
Now add this line:
php_admin_flag safe_mode Off
We have also found that the following works as well if the above does not but DO NOT USE BOTH, pick one!
php_admin_value safe_mode 0
