Making PHP Script Automatically write to text file - php

Question

I am writing a script to try and help make my day to day work easier. It works in parts, sending requests to an API and receiving responses. I then want it to save said responses in a text file that will be automatically emailed to a defined mailbox. The bit I am stuck with, is actually making my script save to a text file.
This is my script: (I'm not very experienced.. the include files aren't relevant, as they send requests the the API and contain nothing else.) I'm hoping that i can literally add a line at the bottom after the SQL connection closes to tell it to save to the text file. Also, I would like the text file to take the name of the "$CorrectCLI" variable.
Any help is appreciated. Cheers.

I would use the PHP output buffer.
Add this code to the top of this PHP script
ob_start("process_output");
function process_output($buffer){
$pageContent = $buffer;
// $pageContent is all the output of your web page,
// put your email logic here
return $pageContent;
}
In your logic I would reference http://php.net/manual/en/function.file-put-contents.php
