Preamble
After many hours, I have been unable to get NetBeans to connect to xdebug. Some months ago, after upgrading from an old version of MAMP to MAMP
I asked the same thing and got this quite good answer: How to track execution time of each line / block of lines / methods in PHP?, beside that i have this answer also on a currently running other question with the same content.
Some additional notes on that (stuff i've collected in other SO posts in my own research with this problem):
xdebug.idekey=netbeans-xdebug
.;
at its begninning), so Xdebug is actually loaded.
