how to upgrade php version
<p>I am using crimson editor which is simply a text editor which uses php version 5.2.13 (I know its old). But I want to update the php version to atleast 5.3 because I want to use the fileinfo command which only works on version 5.3 and beyond.</p>

<p>So my question is how can I upgrade the phpversion easily and safely?</p>
