Assignment of a class-php Tutorial

The problem of assigning a class value is defined as a class.

Class myclass {function test () echo "good" ;}$ test1 = "myclass"; $ test2 = new myclass ();

All assign classes to Variables. What are the differences between the two assignment methods?

What do you score ?? Out there ??? You will know the quantity.

$ Test1 is only a string
$ Test2 is a class instance and an object
Gettype () indicates the difference.

 ShowConstant (); echo $ class: constant. "\ n"; // after PHP 5.3.0?>

The above $ test1 is indeed a string, echo $ classname: constant. "\ n"; why can I access the content in the class?
