PHP is one of the most widely used and supported programming languages by web developers. However, exposing specific PHP version information can lead to security risks. Especially if you do not want to reveal your server’s PHP version to malicious users, these steps are important for you.

Why Is It Necessary to Hide PHP Version Information?
Hiding the PHP version on your server makes it harder for potential attackers. Older and unpatched PHP versions might have known security vulnerabilities. Displaying the version openly can give attackers an advantage by allowing them to target specific exploits faster. Therefore, hiding the PHP version is an important step for your web security.

Methods to Hide PHP Version Information
There are several ways to hide the PHP version, but one of the most common and effective methods is by modifying the php.ini file. Here are step-by-step instructions:

Editing the php.ini File:

  • Locate the php.ini configuration file on your server.

  • Find the line expose_php = On and change it to expose_php = Off. This setting hides the PHP version information.

  • Save and close the file.

Restart Apache and PHP-FPM:

  • Restart Apache and, if used, PHP-FPM to apply the changes.

  • This step ensures that the new settings take effect on the server.

Precautions and Tips
While hiding the PHP version, also consider other security measures such as using strong passwords, regularly applying updates, and employing firewalls.
Hiding the PHP version is only one security measure; creating a comprehensive security policy is essential to close other vulnerabilities.
After hiding the PHP version, verify that your website is still functioning properly. Some applications may require access to PHP version info, so testing functionality is important.

Hiding the PHP version significantly improves the security of your website and server. By setting expose_php = Off, you can obscure your PHP version and make it harder for attackers to target your system. However, remember to consider your overall security strategy and other protections alongside this step.
