Are there alternative methods to include configuration files in PHP projects without using require_once?

When including configuration files in PHP projects, using require_once can sometimes lead to issues such as file path errors or duplicate inclusions. One alternative method is to use the include_once function, which includes the file only if it has not been included before. Another approach is to use the file_get_contents function to read the configuration file and parse its contents as needed. 

// Using include_once to include configuration file
include_once 'config.php';

// Using file_get_contents to read configuration file
$config = file_get_contents('config.php');
// Parse $config as needed
