Php Code Profiling Using X Debug

Download to read offline

Presented by Gennady Feldman at Web Peformance for PHP developers (NY Web Performance Meetup & NY PHP).

Xdebug is a very powerful PHP extension that should be in the toolbox of any PHP developer. In this quick presentation we will do a quick introduction into some of the things Xdebug is capable of and what it can do for you. We'll cover a number of Xdebug features like remote debugging and code profiling. Forget those print and echo statements as your debugging aids. Gennady will share some tips and tricks (time permitting) of how to be a more efficient and productive PHP developer.
