title: Change the php composer uses
body: <p>I am using to start laravel. Therefore I have installed it with composer and somehow it doesn't work after installation i dont see the public folder.. I tried the same steps on my raspberry and there it is installed as it should be; I think the reason that the installation on my macbook doesn't work is that laravel/composer listens to the native php build from my macbook..(5.3.5) ( I am using the one I installed with homebrew php 5.5.3) I have tried many things but with no result. is there a way to delete composer and install it again? ( because i installed the homebrew php a while after installing composer ) </p>
  
  <p>Although ,, if I do composer show I get this </p>
