$15 for help with Rytr api PHP programmer and curl

I'm trying to work out how to connect to this API, there is a link here at github with samples

I want to execute the PHP code there, but I don't understand the curl syntax on the main page, and how that relates to the PHP code I want to use that is shown in samples.

I'm limited in terms of programming scope, as I'm working with a PHP extension inside ubot. I tested a google scraper example PHP code, and that worked ok, so I assume whatever anyone who helps will be easy for you if you know API, and PHP, but not ubot. I'll try to figure that bit out.

Cheers

Bumping and increasing the budget to $20 for this. Another member helped me a bit, but still have issues getting a final output response via the server when I put my API code in.
