Why PHP Is Not Working in HTML
PHP (Hypertext Preprocessor) is a widely-used open source scripting language that is especially suited for web development and can be embedded into HTML. However, there are times when PHP may not work as expected in HTML, causing frustration and confusion for developers. In this article, we will explore some of the common reasons why PHP may not work in HTML and provide potential solutions to these issues.

Common Reasons Why PHP Is Not Working in HTML
1. Improper File Extension
One of the most common reasons why PHP is not working in HTML is that the file extension is incorrect. PHP files should have a “.php” extension, while HTML files have a “.html” or “.htm” extension. If you try to run PHP code in an HTML file without the correct extension, the PHP interpreter will not process the code, resulting in the PHP code being displayed as plain text in the browser.
Solution: Ensure that your PHP files have the correct “.php” file extension to enable the PHP interpreter to process the code.
2. Incorrect PHP Syntax
Another common reason for PHP not working in HTML is incorrect PHP syntax. If there are syntax errors in your PHP code, the PHP interpreter will fail to execute the code, resulting in it being displayed as plain text in the browser.
Solution: Check your PHP code for syntax errors and correct any mistakes before attempting to run the code in an HTML file.
3. Missing PHP Opening and Closing Tags
PHP code should be enclosed within tags in an HTML file. If these tags are missing, the PHP interpreter will not recognize the PHP code and will not execute it.
Solution: Ensure that your PHP code is enclosed within tags in the HTML file to enable the PHP interpreter to process the code.
4. PHP Not Enabled on Server
If PHP is not enabled on the server, it will not be able to process PHP code within HTML files. This is a common issue with some hosting providers or server configurations.
Solution: Contact your hosting provider or server administrator to ensure that PHP is enabled on the server.
5. Incorrect File Permissions
File permissions can also cause PHP to not work in HTML. If the PHP file does not have the correct permissions set, the server will not be able to execute the PHP code.
Solution: Check the file permissions of your PHP files and ensure that they have the correct permissions set to allow the server to execute the PHP code.
6. Incorrect File Paths
If the file paths in your PHP code are incorrect, it can cause PHP to not work in HTML. This is common when including external files or resources in your PHP code.
Solution: Check your file paths and ensure that they are correct to enable the PHP interpreter to locate and execute the necessary files and resources.

You should check these potential issues and correct them to resolve the problem.
Q: How can I enable PHP on my server?
A: Contact your hosting provider or server administrator to ensure that PHP is enabled on the server. They can provide you with the necessary information and assistance to enable PHP on your server.
Q: What should I do if I encounter syntax errors in my PHP code?
A: If you encounter syntax errors in your PHP code, you should carefully review your code to identify and correct any mistakes. Using a code editor with syntax highlighting can also help you identify syntax errors more easily.
Q: Can I use PHP code in an HTML file without the .php file extension?
A: No, PHP code should be saved in files with the .php file extension to enable the PHP interpreter to process the code. Using the .html or .htm file extension will result in the PHP code being displayed as plain text in the browser.
Q: How can I check the file permissions of my PHP files?
A: You can check the file permissions of your PHP files using an FTP client or a file manager provided by your hosting provider. Ensure that the correct permissions are set to allow the server to execute the PHP code.
