Can i get the full HTTP-Header without patching PHP?

Hi, is there a way to get the full HTTP Header without patching PHP? I use a debugger coded in PHP a lot. Now i need to debug some intershop enfinity pages. However, enfinity uses a lot of fields with the same names. So my debugger overwrites the variables and i get only the last one. As i cant change the code (wouldn't work anymore then) i cant debug without having access to the full http header. (i can make arrays for duplicate variables for myself then) Same problem with some kind of e-cash system. It validates itself by putting a signature into the header. However, PHP cant validate the header as i have no chance to get the original header. (And i cant rebuild the original header of course) If there is no way without patching to get these informations are there any plans to integrate a function for getting the header in future versions of php? thanks
