PHP implementation upload files via FTP

In PHP, we can use the ftp_connect correlation function to achieve file upload and download function, in fact, the FTP client is the same operation, I would like to introduce you to the use of PHP to achieve

Approximate principle

Iterate through all the non-excluded files in the project, and then get files that were modified later than the last time the file was modified

Then upload these files to the corresponding directory via FTP

The specific code is as follows:

Because it's just a tool, the code is messy, forgive me
