title: Set alias php=/bin/php56 but today it has reverted to it's original path: /bin/php
body: <p>I'm using CentOS 7's remi and remi.safe repository. Remi installs PHP 5.4 to /bin/php and Remi Safe installs PHP 5.6 to /bin/php56.</p>
  
  <p>When php is executed from the console, I want it to reference php56. Yesterday I set <code>alias php=/etc/php56</code> which seemed to have resolved the issue. Today, when I execute php -v it outputs:</p>
  
  <pre><code>PHP 5.4.16 (cli) (built: Jun 23 2015 21:17:27)
  Copyright (c) 1997-2013 The PHP Group
  Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies
  </code></pre>
  
  <p><strong>Edit:</strong>
  I added <code>alias php=/bin/php56</code> to /home/{user}/.bashrc, logged out and logged back in and it did resolve it for that user. </p>
  
  <p>Is it recommended, to set this globally, to do so via /etc/bashrc?</p>
