PHP Array Syntax -> MailChimp Merge Syntax - 408 entries

I recently needed to send an e-mail to our marketing department listing allowed merge tags for our MailChimp campaigns.

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!
