Message Sending API (Unofficial) for Way2SMS [ PHP ]

Recently I looked through the website http://site24.way2sms.com/content/index.html and mapped the parameter which were used used in get and post forms. By using the Curl library i was able to send messages through Command Line for free . For mapping the get and post parameters , I used Developer Tools in Chrome . Below i'm sharing the snippets of my php library for way2sms so that anyone could be able to send messages on mobile by using this easy to use API.
