Convert (NOT TRANSLATE) Farsi letters to English letters like Google Translate in PHP

I want to convert Farsi letters to English letters in PHP and I don't want to translate them. In Farsi we call it Finglish or Pinglish as you can see here :

سلام -> Salam
علی -> Ali

and so on, I searched the web but didn't find any useful API to use. Any idea?
