I use PHP version 5.4 of the PHP toolbox, and the verification code can be displayed, but it cannot be displayed when I switch to PHP version 5.6 or 7. What I tested was the verification code class that comes with the tp5 framework. What's going on?

Because there is a problem with the php version library, it has nothing to do with the software. Find the official documentation of php for the specific reason!

There may be a problem with the compatibility of the PHP version. Please check if the specific reason is caused by the library. It is recommended to read the official documentation of PHP.

Verification code refers to the verification code picture. Generated using the GD library.
