title: Upgrade PHP on my mac OS X 10.5
body: <p>I'm running on OS X 10.5 (Leopard), and I want to update the current version of PHP 5.2.15 (cli) that I have to PHP 5.3 or even 5.4.</p>
  
  <p>The matter is that I need to run some PHP snippets in my terminal, and the version that i have (<em>PHP 5.2.15 (cli) (built: May  5 2011 18:56:00)</em>) can't allow some functions. That's why I need to upgrade my current version.</p>
  
  <p>I searched on the web, but didn't find anything. How can I do it ?</p>
  
  <p>Thanks !</p>
