Automate php code.

Hello, I have this code that login and sendMedia. Code: [login to view URL] I want to automate this code to make it work like below: (Login to account1 user:pass then -> SendMedia to 50 usernames). So each account will send images to 50 usernames. And I have a list of accounts in [login to view URL] and Usernames list in [login to view URL] Proxy rotaton support. (I have the code just need to be implemented). I have most of the code. Just need somebody to manage it and modify it. That's it!
