在eclipse中使用XDebug远程调试时，PHP源文件是否需要在本地和远程存在？

Question

I'm really confused about XDebug remote debugging using Eclipse.

I use Windows (with eclipse and all that jazz) to do my development, but I would like to test my code in the same environment as my production environment.

I have been tinkering with XDebug remote debugging to support this. I have correctly configured XDebug on the remote machine and made sure the ports were open. But what's really puzzling me is - do the source files on my machine need to also exist on the remote server running PHP and XDebug? Right now I do not have any PHP executables on my local development machine so there's no possible way the scripts can be run on it.

Thanks

Yes, the identical set of files needs to exist on the server and client.

The files on the server are the ones that actually get run during your debugging session.

The files on the client are what Eclipse will show you when the debugger halts at a breakpoint. The server will tell Eclipse that it stopped at line X of file Y, and Eclipse will show you line X of file Y from the local file set. So if the local file is different from the remote file, you'll be debugging the wrong thing and it will be chaos.

Note that it doesn't matter if you can't run PHP on the client. The client files aren't being executed, just displayed in the debugging session.

If you make any edits to the local files, you'll need to resynchronize them with the server. There are several methods for doing that, some built into Eclipse, in the RSE plugin for example. I prefer to use Unison , or a version control commit back to the server.

XDebug can be used in a couple different ways, but yes, it is typical to have source files both locally and remotely. I've not used Eclipse, but typically in this configuration the IDE will perform a file upload when you "Run" the project to make sure the server has the code you're editing locally.

I prefer a setup where the files exist only on the server, but are mounted locally (over SFTP or SMB). There's no need to upload files every time you run the project that way, but there's some extra work setting up path mapping so that when XDebug on the server reports "line 10 of /var/www/foo", your local IDE understands that means "line 10 of ~/MyProject/foo".

I can't be more specific without knowing how your Eclipse project and server are setup.

Also, you may want check out NetBeans (free), or PHPStorm (not free, but better) for PHP development. I've heard from coworkers that Eclipse can be flaky with XDebug (they were using Windows). I've never had the same issues on Linux with NetBeans or PHPStorm, though I have had similar flakiness on a Mac running NetBeans.
