The only things I managed to get working reliably with xdebug were

• break at the first line in a script (very annoying when you have to debug something very deep)

• generate tracing logs (horrible to read but the best debugger replacement I had at the time)

• generate profiling logs (very helpful)

I never managed to get arbitrary breakpoints to work so I basically resorted to either traces or var_dump.
