possible to check mac address with php code

No, it’s not possible to directly check the MAC address of a client machine using PHP code. The MAC address is a hardware address that operates at the data link layer of the OSI model and is typically not exposed to web applications or PHP scripts running on a server.

PHP is a server-side scripting language, and it operates in a sandboxed environment on the server, interacting with the client through HTTP requests. It does not have direct access to low-level networking information, such as MAC addresses.

If you need to obtain client-side information, you may consider using JavaScript on the client side, but even then, accessing the MAC address is not straightforward due to browser security restrictions. Modern browsers intentionally restrict access to sensitive system information for privacy and security reasons.

Keep in mind that attempting to access sensitive information without the user’s knowledge and consent may violate privacy and security principles, so it’s essential to respect user privacy and adhere to best practices.
