thinkphp Call common/common.php function hints error function undefined resolution _php instance

This paper mainly introduces the solution of thinkphp call common/common.php function hint error functions undefined. For friends who use thinkphp for project development, they often encounter such problems after a thinkphp upgrade. The detailed description is as follows:

After the thinkphp upgrade, the most recent ThinkPHP3.2 version was used, and the common functions were put into common/common.php, but the function undefined error was prompted when the functions were called on a specific page.

After viewing the official document, I found that the original ThinkPHP3.2 version common.php file has been renamed Function.php,
So the common.php---> replaced function.php, the function call success! Problem solved!

It is hoped that the method described in this paper will help us thinkphp development.
