PHP Array Syntax -> MailChimp Merge Syntax

I recently needed to send an e-mail to our marketing department listing allowed merge tags for our MailChimp campaigns. The allowed merge tags were determined from a PHP array in one of our PHP classes. I transformed the PHP class to MailChimp's syntax and sent the e-mail. It was, however, a long, laborious process. I'm still fairly new to Vim and would love to see how an expert Vim user would tackle one of my own, real-world problems. Thanks and have fun!
