title: How to change php-cli Version (Wamp)
body: <p>I have since a long time a wamp installation with php 5.3.5
  Now I'm working with Symfony2.1, and need intl extension 
  So I downloaded &amp; installed php 5.4.6 and things worked fine in a first time</p>
  
  <p>But now I'm on a new project where I need to install via the php console (php-cli) some required bundles.
  One of this bundles is sonata-project/intl-bundle
  when asking for update by "php composer.phar update"
  I get error messages that seems to say that the intl extension is not installed</p>
  
  <p>After some Googleing I understand that my php-cli version is still 5.3.5
  So I tried to change my windows XP environmental variable PATH and replaced the 5.3.5 path by the 5.4.6 path
  But now I get the following error on the dos console :</p>
  
  <pre><code>Failed loading c:/wamp/bin/php/php5.3.5/zend_ext/php_xdebug-2.1.0-5.3-vc6.dll
  PHP 5.4.6 (cli) (built: Aug 15 2012 21:16:03)&lt;/br&gt;

  Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies&lt;/br&gt;
  </code></pre>
  
  <p>is there anyone who can help me fix this ?</p>
