What could be the problem with php notice: Use of undefined constant string - assumed 'string' in?

Question

PHP

I can’t understand what the error is, it says Notice Notice: Use of undefined constant string - assumed 'string' in
You can, of course, remove the output of notice errors, but still unpleasant

function system_load($name,$options = array()) {
    $name = strtolower($name);
    $file = ROOT . 'system/core/' . $name . '.php';
    if (is_file($file)) {
        require_once($file);
        if (class_exists($name)) {
            if (count($options) > 0)
            return new $name($options); 
        else return new $name;
        } else return FALSE;
    } else
        return FALSE;
}

It throws an error on the line: return new $name($options);

Answer 1

Most likely, the error is not in this function, but in the class file, an instance of which is created through new.
