Why Is Apache Displaying My PHP Code Instead of Executing It?

Apache Rendering PHP Code Instead of Executing: Diagnosis and Resolution

In the described issue, PHP code is displayed on the browser instead of being executed by Apache. To resolve this, follow these troubleshooting steps:

Enable PHP Module:

• Navigate to the mods-enabled folder in the Apache directory (typically /etc/apache2/).
• Check if a file with a name like "php.so" or similar exists. If not, enable the PHP module by creating a symbolic link from the php5apache2_2.dll (or similar) file located in the PHP installation directory.

Verify HTTP Configuration:

• Ensure that the AddType directives in the httpd.conf file are correctly configured:

  AddType application/x-httpd-php .php
  AddType application/x-httpd-php-source .phps

Check PHPIniDir:

• Ensure that the PHPIniDir directive in httpd.conf is set to the correct PHP installation directory, as in the example provided.

Check Error Logs:

• Examine the error.log file in /var/log/apache2/ for any additional error messages that may indicate the root cause of the issue.

Additional Considerations:

• Restart the Apache service after making any configuration changes.
• Verify that the phpinfo() function is correctly implemented in the PHP script.
• If using Windows, check that the PHP extension is enabled in the PHP Manager module.
