What are common beginner mistakes when setting up and running PHP scripts with a web server like Apache?

One common beginner mistake is not enabling the PHP module in Apache's configuration. This can be solved by ensuring that the PHP module is enabled and the necessary configuration settings are in place. ```apache # Ensure the PHP module is enabled LoadModule php7_module modules/libphp7.so # Set the PHP handler AddHandler php-script .php ``` Another common mistake is not setting the correct file permissions for PHP scripts, leading to permission denied errors. This can be fixed by setting the appropriate permissions for PHP files. ```bash # Set correct file permissions for PHP scripts chmod 644 index.php ``` Lastly, forgetting to restart the Apache server after making changes to the configuration can also cause issues. This can be resolved by restarting the Apache server to apply the changes. ```bash # Restart Apache server sudo systemctl restart apache2 ```
