Bin/grav install not working


I just downloaded the latest grav version (core + admin) and tried to install it with the command

bin/grav install

And I got this error:

webspace-user mywebspacepath/ $ bin/grav install
X-Powered-By: PHP/4.4.9
Content-type: text/html

Parse error: syntax error, unexpected T_STRING, expecting T_CONSTANT_ENC APSED_STRING or '(' in /kunden/507972_4457/webseiten/ on line 9

The PHP version seems up to date:

webspace-user mywebspacepath/$ php -v
PHP 5.6.12 (cli) (built: Dec 26 2015 15:38:45)
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies

Does anyone know how to fix this?

You are using PHP 4.4.9. Grav requires PHP 5.5.9 or higher. Note that the CLI version of PHP might be different than the one used in the frontend.
