I am running OS X 10.11.5 and using homebrew to compile Apache/2.4.18 (Unix) PHP/5.6.24.

Homebrew php56-xdebug compiled and enabled. Shows up in PHP Info.

This program makes use of the Zend Scripting Language Engine:

MacGDBp prefs set to port 9000

Network Utility reports:

Port Scanning host:
Open TCP Port: 9000 cslistener

PHP.ini configure reads:


So: Xdebug is compiled and loading, shows up in phpinfo().
Port 9000 is open.

Everytime I launch MacGDBp @ 9000, there is a message in red in the bottom status bar of the main debugging window that says:

Could not open socket.

Any suggestions on why this is happening? No discussion in the docs or FAQ's

Thanks In Advance.

Well, It Turns Out that... Homebrew PHP uses port 9000 to talk, I think, to Apache.

So I configured PHP.so and MacGDBp to use port 9001.

And now it works.

Worth pointing out in the docs somewhere...

Thanks for figuring that out. I added a note about FastCGI to the help page: https://www.bluestatic.org/software/macgdbp/help.php#socket-errors

This might be sound redundantly obvious, but the example would be :

Set the Port Directive in PHP.ini to (say) 9001.
Set the Port Preference in MacGDBp to 9001.

Adding that to your docs would provide a working example.
