How to Hide PHP Version in Linux
Sometimes we need to hide PHP version from our webserver to hide PHP version identy. It helps us to prevent malicious attacks. In this article, I’m going to show you the way to hide PHP versin.
Solution 1
Find PHP configuration file (php.ini) location:
php -i | grep 'Configuration File'You’ll see the output like:
Configuration File (php.ini) Path => /etc
Loaded Configuration File => /etc/php.iniNow open the php.ini file:
sudo nano /etc/php.iniSearch for this line:
expose_php = on
Now change its value to:
expose_php = offNow restart webserver:
sudo systemctl restart httpd # centos
sudo systemctl restart apache2 # ubuntuSolution 2
If you don’t have access to php.ini, you can do it from PHP code. We need to remove X-Powered-By from header. X-Powered-By is set by various servers to say what kind of server it is.
Just add this line add the begining of PHP file:
<?php header_remove("X-Powered-By"); ?>We can aslo remove specefic header. Have a look at an example:
<?php header("X-Powered-By: CUSTOM-HEADER"); ?>Share on Social Media
