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.

Using PHP Safe_Mode
First of all we’ll take care of the files that you will edit, and make sure to have copy or backup .

Activate Safe Mode Globally
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.

http://www.webhostgear.com/phpinfo.phps

Save it as phpinfo.php and upload it to a website that you want to test on your server. Type in the URL and you’ll get a PHP configuration page telling you exactly where php.ini is located and all kinds of other useful information about the sites and servers configuration settings.
