title: Convert (NOT TRANSLATE) Farsi letters to English letters like Google Translate in PHP
body: <p>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 :</p>
  
  <pre><code>سلام -&gt; Salam
  علی -&gt; Ali
  </code></pre>
  
  <p>and so on, I searched the web but didn't find any useful API to use.
  Any idea?</p>
