If you need it, refer to this article to introduce ThinkPHP to call common/common. php function prompts the error function undefined solution. For those who use ThinkPHP for project development, ThinkPHP upgrades often encounter such problems. The detailed description is as follows:

After ThinkPHP is upgraded, the latest ThinkPHP3.2 version is used to put common functions into common/common. php. However, the function undefined error message is displayed when the function is called on a specific page.

After checking the official documentation, we found that the original ThinkPHP3.2 common. php file has been renamed function. php,
