Hide PHP version (X-Powered-By) Header

Filed under: Linux,Miscellaneous,Security Tips and Issues — Nasser Heidari @ 09:09

In your php.ini (based on your Linux distribution this can be found in various places, like /etc/php.ini, /etc/php5/apache2/php.ini, etc.) locate the line containing “expose_php On” and set it to Off:

expose_php = Off

After making this change PHP will no longer add it’s signature to the web server header. Doing this, will not make your server more secure… it will just prevent remote hosts to easily see that you have PHP installed on the system and what version you are running.
