';} // Static method public static function static_stuFunction () {echo 'static _ function ','

';} // Automatically call public function _ destruct () {echo' _ destruct ','
';}} // Instantiate class object $ object = new Student ('Tom'); // call the property echo $ object-> stu_name ,'
'; // Static property echo $ object: $ stu_num ,'
'; // Class call static property echo Student: $ stu_num ,'
'; // Use an object to call methods and static methods, respectively. $ object-> stuFunction (); $ object-> static_stuFunction (); $ object: stuFunction (); $ object :: static_stuFunction (); // use classes to call methods and static methods respectively Student: stuFunction (); Student: static_stuFunction (); // class call class constant echo Student: STUDENT,'
