I have shared hosting with PHP 5.3.8 where I cannot run Composer.
Yesterday I have installed Composer to my own computer and then I have "build" Restler with it. It has downloaded Illuminate too. Then I've uploaded them to my shared hosting and it didn't work because apparently Illuminate requires minimum PHP 5.4.
So, is there any possibility to specify PHP version for Composer? Or I should have switched PHP 5.6 off, and then PHP 5.3.x on on my PC.
