PHP debugging on OS X - hopeless?

You may want to look into MacGDBp. It's new, free, and the UI looks great. It utilizes the Xdebug PHP extension as well. You can find instructions in the help section, which includes Xdebug configurations, and there's also a nice overview of the app from the guys at Particletree here: Silence The Echo with MacGDBp.

Just wanted to update this thread to let you know there's a new app out here http://codebugapp.com/ it's commercial, but it's Xdebug client for OSX

Here's how I did it:

1 - Copy the latest version of xdebug.so from http://aspn.activestate.com/ASPN/Downloads/Komodo/RemoteDebugging to /usr/libexec.

2 - Add the following to the global php.ini:

zend_extension="/usr/libexec/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_host=localhost
xdebug.remote_port=9000
xdebug.remote_autostart=1

3 - Restart Apache and run MacGDBp.
