How can one ensure proper directory permissions are set for PHP websites to avoid the 403 error?

To ensure proper directory permissions are set for PHP websites to avoid the 403 error, you can set the correct permissions for the directories where your PHP files are located. This typically involves setting the directory permissions to 755 and the file permissions to 644. This will allow the web server to access and execute the PHP files properly without encountering any permission issues.

// Set directory permissions to 755 and file permissions to 644
chmod("/path/to/directory", 0755);
chmod("/path/to/file.php", 0644);
