how does php composer know the php version?
<p>Having successfully upgraded my test site (Debian Linux) to Zend Framework 3, I want to repeat the exercise on OS X El Capitan running Server 5.1.5.  Originally this had PHP 5.5.x installed but I've upgraded to PHP 5.6.x and verified this with a phpinfo() display.  However, when I try to run composer to install Zend Framework 3 modules, it responds that it can't be done as PHP 5.5.x is installed. Restarting etc. makes no difference. How does composer tell which PHP version is in use and how can I convince it that PHP 5.6.x is installed?</p>
