but forgot to add PHP support, and there are a whole bunch of situations that can lead to source code exposure. You can prevent source code from being exposed by saving as much PHP code as possible outside of your website's home directory. At the very least, it's a good idea to keep all of the included files outside the home directory. Some methods can limit the

To determine whether the passed variable contains illegal characters, we put the following code into a public file, such as security. inc. in php, every file contains this file, so that all variables submitted by any program can be filtered out, which achieves our effect once and for all.

While there is only such a confirmed action, the synchronization state of the main library in S
