How can the PHP configuration settings be checked to troubleshoot issues with executing system commands for database backup?

To troubleshoot issues with executing system commands for database backup in PHP, you can check the PHP configuration settings related to the `disable_functions` directive. This directive can prevent certain functions, like `exec()`, from being used to execute system commands. By checking and adjusting this directive, you can ensure that the necessary functions for database backup are allowed. 

// Check the disable_functions directive in the PHP configuration
$disabled_functions = ini_get('disable_functions');

// If necessary, remove 'exec' from the disabled functions list
if (strpos($disabled_functions, 'exec') !== false) {
    $disabled_functions = str_replace('exec', '', $disabled_functions);
    ini_set('disable_functions', $disabled_functions);
}
