title: Install xdebug on specific php version
body: <p>I'm trying to install xdebug.</p>
  
  <p>I've already seen some issues about it (like this one : <a href="https://stackoverflow.com/questions/20457856/installing-xdebug-with-php-5-5">Installing xdebug with PHP 5.5</a> ) but it seems outdated and not corresponding to my issue).</p>
  
  <p>When I try </p>
  
  <p><code>sudo pecl install xdebug</code></p>
  
  <p>I'm getting the following error</p>
  
  <blockquote>
    <p>WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update</p>
    
    <p>downloading xdebug-2.8.0.tgz ...</p>

    sh: 1: phpize: not found
    ERROR: `phpize' failed</p>
  </blockquote>
  
  <p>It seems that means phpize isn't installed in my php version</p>
  
  <p><code>php -v</code></p>

  <p>So, some topics seems to tell me to change my php version to download a version with phpsize included. But I was more looking for a way to add phpsize to my current php version but I don't know how to do that.</p>
  
  <p>Thanks for your assistance</p>
