[php] dump

http://symfony.com/doc/current/components/var_dumper.html

The VarDumper Component

The VarDumper component provides mechanisms for extracting the state out of any PHP variables. Built on top, it provides a better dump() function that you can use instead of var_dump.

今天才發現有這個function可以用，debug方便多了~

例如把 $request dump() 出來
