Laravel Installation problem

I have set php as php 7.0.12 as optional php and enabled it for a specific vhost.
I have joomla installed in the root folder. In joomla system information, the php version showing is PHP7.0.12
But when I am trying to install laravel in a subfolder(TWL) of the vhost. I am getting the error.

Code:

 - laravel/framework 5.2.41 requires php >=5.5.9 -> your PHP version (5.3.10) does not satisfy that requirement.

How I can overcome that?

 

Thanks. If anyone else faces same problem. The solution is simple one.

Code:

composer install --ignore-platform-reqs
