PhpStorm | WebMatrix (IISExpress) | Xdebug.remote_

Question

I've got a localhost webserver setup with WebMatrix and its IISExpress. It runs the webserver as http://localhost:<port>.
I've also installed xdebug in it which runs perfectly for error-handling purposes.

Now I have installed PhpStorm and I want to make use of its debugger's break-point wizardry. It uses Xdebug's /?XDEBUG_SESSION_START=<IDEKEY> feature and This is where I'm having trouble.

In all, I have 3 places where I can set PORT:

• (a) Port in xdebug.remote_port in php.ini.

• (b) Port in WebMatrix.

• (c) Port in PhpStorm's Server settings, in Run/Debug configuration

EDIT: There's an error here: All those extra "quotes" and ;colons;.

So far messing around, I've come to the conclusion that all three cannot be the same. otherwise it gives errors...

Which port to use where?

Answer 1

xdebug.remote_port is used for the debugger connection, it must be different from the HTTP web port that you are using to access the page in a browser.

xdebug.remote_port needs to be the same as specified here:

HTTP port (80 is the default for most servers, but when testing it could be 8080 or whatever you have configured in your web server settings) is configured here:

You may find it easier to use Zero Debug Configuration instead of using PHP Application Run/Debug configuration.
