I have no idea how I managed to program in PHP for years without Xdebug. Now when an error occurs, it just pops up in my IDE, and I can set breakpoints and see ALL of the local variables including the ones set in the higher up scripts. It makes debugging sooooo much easier.
I feel kind of silly for not assuming a tool like this existed and hunting for it. I’ll never write a var_debug() again. I wonder what other absolutely vital tools are out there that I’m just completely oblivious to.
Just wait until you learn that debuggers for XSLT exists. Wait, that’s no reason to smile.
