Static-What is the difference between a version before 5.3 in PHP and a version after 5.3 in a static class?

I contact PHP are in contact with 5.6 version of the previous version did not contact to seek the help of Master,

My PHP with 5.3 version will not error,

has been changed to version 5.6 began to error that static classes can not be used, the static public function () {...}

PHP syntax change specification, become rigorous, so previously did not conform to the code will give hints, it is good, you have to get used to.

ecshopcls_image gd_version is not a static method in the library

Calling Non-static methods statically generates an E_STRICT level warning.
Invoking a non-static method in a static manner results in an e_strict level error.
