title: Tell Apache to use a specific PHP version installed using phpbrew
body: <p>I had the PHP, MySQL, and Apache stack installed for development. That installation is using configuration files from:</p>
  
  <pre><code>/etc/apache2/
  /etc/php5/
  </code></pre>
  
  <p>Later I installed multiple PHP version using <code>phpbrew</code>. All versions are accessible and switchable from CLI. But Apache always stays on the default version that was not installed using <strong>phpbrew</strong>.</p>
  
  <p>Here is a list of my installed PHP versions.</p>
  
  <pre><code>$ phpbrew list
  Installed versions:
    php-5.4.13       (/home/admin1/.phpbrew/php/php-5.4.13)
                     +default -- --with-bz2=/usr
    php-5.5.5        (/home/admin1/.phpbrew/php/php-5.5.5)
  
    php-5.3.27       (/home/admin1/.phpbrew/php/php-5.3.27)
  </code></pre>
  
  <p>I have tried changing configuration file paths so they point to phpbrew's PHP. But nothing seems to be working.</p>
  
  <p>How can I tell Apache to use phpbrew's PHP version?</p>
