Xdebug is a powerful debugging and profiling tool for php that allows you to find and fix errors faster by showing the entire stack trace and source code file and line number.
If you want your php development to be error free you should use something like xdebug right from the beginning.

xdebug.scream = 1
The halt_level setting determines whether notices and warnings are reported as errors.
