Why is PHP Not Working in my HTML files?

There could be several reasons why PHP is not working in HTML. Here are some possible scenarios:

• Server doesn’t support PHP: PHP is a server-side scripting language, and therefore it requires a server that can process PHP scripts. If your server doesn’t support PHP, your PHP code will not be executed.
• PHP is not properly installed or configured: If PHP is not installed on your server or if it’s not correctly configured, it can cause issues. You might need to check your server’s PHP installation and configuration.
• Incorrect file extension: In order for the server to recognize and process PHP code, the file should typically have a .php extension. If your file has a .html extension, the server might not process the PHP code inside it. You can still include PHP in a file with a .html extension, but you would need to configure your server to process HTML files as PHP.
• PHP tags are not used properly: PHP code should be enclosed within tags. If these tags are missing or used incorrectly, the PHP code will not be processed.
• Syntax errors in the PHP code: If there are any errors in your PHP code (such as missing semicolons, unclosed braces, etc.), it can prevent the code from running properly. Make sure your PHP code is error-free.
• Code is outside of PHP tags: All PHP code must be inside PHP tags. If it’s not, it won’t be processed as PHP.
• Running HTML files directly: If you are trying to run your .php files directly from your file system (i.e., by double-clicking the file), your PHP code will not be processed. PHP code is processed on the server, so you need to access your files through a server (like using localhost if you are using a local server).

Remember, it’s always a good practice to enable error reporting while you’re debugging in PHP. You can do this by adding these lines at the top of your PHP script:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
