Moving from asp.net to php
<p>I am an asp.net web developer. Recently I have recieved a job offer to write a website in php (I'll be upgrading an already written code).</p>

<p>I wanted to know, how much time will it take me to learn the langauge? How different is it from asp.net? Do people usually go from asp.net to php, or is that the other way around?</p>

<p>Thank you</p>
