Note

This article assumes that you have already set up a custom php.ini file on your web site. If you have not already set up a custom php.ini file, please read this article first.

Using the expose_php directive

When the expose_php directive is enabled, PHP includes the following line in the HTTP response header when a PHP page is requested (the exact version number may differ depending on your configuration):

X-Powered-By: PHP/5.3.27

By default, the expose_php directive is enabled. However, you may not want to broadcast the specific PHP version your site is using. Similarly, some third-party applications require the expose_php directive to be disabled.

To disable the expose_php directive, use a text editor to modify your php.ini file as follows:

expose_php = off

With the expose_php directive disabled, PHP will not send the X-Powered-By header. To re-enable the expose_php directive and send the X-Powered-By header, modify your php.ini file as follows:

expose_php = on

👍

Tip

To verify the current value of the expose_php directive and other directives, you can use the phpinfo() function. For more information, please see this article.
