Mixed vagrant enviroments, check where does url load from

I had many vagrant machines and haven't really paid much attention to setting unique hostname, machine name and IP address, which resulted in mixed environments. Meaning I loaded one URL and I got files and database from the other vagrant machine. To debug what was really happening I went into devel/php and found out where is my mind I mean Index file :) to do that I echoed it like this.

$stack = debug_backtrace();
$firstFrame = $stack[count($stack) - 1];
$initialFile = $firstFrame['file'];


After that I went on and fixed my environments and took better care of them.
