title: Force linux to use php as php55
body: <p>Helllo,
  I have a little problem here.</p>
  
  <p>I have PHP 5.3 installed and it's accessible via <code>php</code> command, I also have php 5.5 accessible as <code>php55</code> command.</p>
  
  <p>Now I need to force linux to use <code>php55</code> when I write <code>php</code> command. </p>
  
  <p>Simple way: How I switch the versions of php?</p>
  
  <p>I am using Fedora 21 OS</p>
