Laravel not installing dependencies incorrect php version

I cannot install all the laravel dependencies because of the php version but I'm using xampp with (PHP 7.0.13) using echo phpversion(); to determine my php version but this laravel keeps telling me that I'm using php version 5.4.24 when I'm installing a new laravel directory.
