Restricting PHP information leakage is crucial for enhancing the security of PHP-based applications. By minimizing the amount of information exposed to potential attackers, you can reduce the attack surface and make it more difficult for them to exploit vulnerabilities. Here are some effective strategies to restrict PHP information leakage:

Disable Exposing PHP Version and Header Information:

By default, PHP includes the X-Powered-By header, which reveals the PHP version being used on the server. This information can be valuable for attackers in identifying potential vulnerabilities. To disable this header, edit the php.ini configuration file and set the expose_php directive to Off.

Example:-

Go to php.ini and disable

Put below code

expose_php=Off

By implementing these strategies, you can significantly reduce the risk of PHP information leakage and enhance the overall security of your PHP-based applications. Remember that security is an ongoing process, and continuous vigilance is essential to maintain a secure environment.
