I was trying to install PHP 5.6.11 into Openshift "Do-it-Yourself 0.1". After the installation, I restarted all the services via "ctl\_all restart". But after that, when I run "php -v", it showed:

```
PHP 5.3.3 (cli) (built: Jul  3 2015 03:10:33)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies
    with Xdebug v2.1.4, Copyright (c) 2002-2012, by Derick Rethans

```

How can I replace this built-in version of PHP with PHP 5.6.11? Thanks.
