I'm trying to setup a websocket server in a development pc. I've been trying a few examples from github and all of them with the same result. Error 500 after a few minutes.
I already have enabled the websocket protocol on Windows optional resources, the extension is included in the php.ini file. I tried running the scripts on CMD and nothing seems to work. I also tried inserting a few breakpoints using xdebug and the script is being reached, it just keep refusing to perform the handshake. Is there anything that I may be missing?
The PC is running Windows 10, with PHP 5.6.3.
I have a similar problem to Setting up IntelliJ Idea remote debugging with XDebug, but since no solution was posted there I'll ask it anyways.
I have a Raspberry Pi with Apache 2, PHP, xdebug set up and running on a local network.
I have a desktop with IntelliJ IDEA and the PHP plugin running in the same local network. I already successfully made an SSH connection to the remote server from IntelliJ, so when I hit "Run" it automatically uploads local files to the Raspberry Pi and opens a browser showing the php website. Now I want to be able to debug as well. I followed this page mostly: https://www.jetbrains.com/help/idea/2016.3/configuring-xdebug.html, but it is not working.
When I hit debug the browser opens with ?XDEBUG_SESSION_START=15930 appended to the URL and I see my php website. In IntelliJ the Debugger window opens with the message "Waiting for incoming connection with ide key '15930'". This number changes every time I hit debug, so I have not set xdebug.idekey in php.ini.
This is the contents of my php.ini:
[XDebug]
zend_extension = /usr/lib/php5/20131226/xdebug.so
xdebug.remote_enable=1
xdebug.remote_port=9000
xdebug.remote_mode=req
xdebug.remote_host=192.168.2.108
xdebug.show_exception_trace=On
xdebug.remote_handler=dbgp
xdebug.remote_conneck_back=1
Any ideas what might be wrong? Something with firewall settings to allow incoming connections on port 9000?
For those struggling with the same problem, the answer probably can be found by checking if your server and client make appropriate connections on the specified debug port 9000. Since in my situation there are multiple routers between the client and server and my port forwarding options in those routers are limited I kind of gave up on this approach.
Instead I installed xampp on my client and went for local debugging instead of remote debugging.
I'm setting up xdebug for php within sublime text, and xdebug keeps on logging errors related to being unable to connect:
Log opened at 2016-08-18 21:06:01
I: Connecting to configured address/port: localhost:9988.
E: Could not connect to client. :-(
Log closed at 2016-08-18 21:06:01
I hoped that debugging directly by going to http://localhost:9988 in my browser might help, but it simply displays the google chrome error page: "localhost refused to connect". Perhaps the error exists on the other end, that data can't be pushed to the sublime text client, I don't know. Sublime text xdebug does show the message "Reloading /var/log/xdebug/xdebug.log" when I run tests/etc, so it seems to be aware of the php code being run, just doesn't get any further.
So, I never thought I would have to debug xdebug itself, but: How can I debug the xdebug to code editor connection? If this were nginx, I would start debugging the virtualhost, but since it's xdebug... ...I have no idea where to start debugging the lack of an app to connect to?

phpinfo xdebug settings:
PHP debugging requires two components that collaborate: a PHP extension that acts as server and a software that knows how to talk to this extension and drive its functionality (it is the client).
However, despite the usual client-server protocols where the client connects to the server, the PHP debugger works the other way around: the server is the one that connects to the client (that should be started and listening on port 9000).
xdebug is the most known PHP extension for debug. There are many programs and program extensions/plugins that acts as clients for it. I didn't work with Xdebug package for Sublime (I didn't work with Sublime, in the first place) but the principles are the same.
How a debugging session works?
The client software (Sublime with the Xdebug package in your case) starts listening on port 9000 of localhost, waiting for the server to start the connection. It probably doesn't listen on the port all the time but only when the developer tells it so.
You start the PHP script to debug. xdebug doesn't kick in on all requests to the server but only when it finds a marker in the request. Depending on the SAPI used to run the script, the marker is either an environment variable (for CLI scripts) or a cookie or a GET or POST argument (for web pages). Read more on the "Starting The Debugger" section of the documentation.
When the PHP interpreter starts the execution of the PHP script, if xdebug finds the marker explained above then it tries to connect the xdebug client. Otherwise, it stays out of the way and lets the script run at its full speed.
When the debugging marker is present in the environment, the xdebug extension (the server) tries to connect to the xdebug client (by default on port 9000 of localhost but these settings can be changed as needed). If it cannot connect (because the client is not listening) then it logs the failure then puts itself out of the way and lets the script run at its full speed.
After it successfully connects to the client, the xdebug PHP extension either stops before running the first statement of the PHP script or runs the script until its execution reaches a breakpoint. This behaviour and the list of breakpoints are sent by the client to the server during their initial communication as the connection was established. Then the extension waits for commands from the client. The client displays to the developer the current state of the running script (the next statement to run, the values of the variables in the current scope etc) and waits for commands (run next statement, continue, add/remove breakpoints, watch some variable etc).
Why it doesn't work for you?
It's not very clear for me from your question but I'll assume you run the webserver (with the PHP interpreter and the xdebug extension) on the same computer you run the xdebug client (localhost). If this is not the case, don't despair. The solution is a command line away (read at the end of the answer).
From the information you posted in the question is clear that xdebug is installed, enabled and it works properly. The output of telnet localhost 9988 says nobody is listening on port 9988. The xdebug client should listen there.
I never worked with Sublime Text (and its packages). This article explains how to install and make it work. However, it doesn't explain how to configure it to listen on port 9988.
I would start by setting the PHP xdebug extension to connect to the default port (9000):
xdebug.remote_port=9000
and then, if everything works, I would try to find out how to configure the Sublime Text xdebug package to listen on a different port. Do you really need it to listen on a different port?
What if the web server and the xdebug client are on different computers?
If you need to debug a PHP script that runs on a remote machine the xdebug client listens on the local machine (on port 9000) and the xdebug extension tries to connect to port 9000 on the remote machine. A solution that is possible in intranets and VPNs is to configure xdebug to connect to port 9000 of the local machine but, apart from these conditions, it usually also requires changes in the firewall and/or other security software.
The easiest way to debug the PHP scripts in this situation if you have ssh access to the remote machine is to create a ssh tunnel from port 9000 of the remote machine to port 9000 of the local machine.
Assuming you use ssh to connect to the remote machine (to put the files on it), all you have to do is to append -R 9000:localhost:9000 to the command line you use to connect and start a ssh session to the remote machine.
As long as this connection is open, any connection request on port 9000 (the first 9000 on the command line above) of the remote machine (-R) is forwarded through the tunnel to the port 9000 (the second 9000 from the command line) of the local machine (localhost). This way the remote xdebug PHP extension is able to contact the remote xdebug client (assuming it is listening).
If you are using xdebug-v3, please try:
xdebug.mode=debug
xdebug.start_with_request=yes
xdebug.discover_client_host=1
This should solve your issue.
Ok, so after extensive testings of different settings, here are my suggestions for debugging the problem for people who come after me:
Do not rely on testing with only 1 xdebug client! It's trivial to install two editors/IDEs, so get an alternate editor running to make it possible to see whether there is a problem with xdebug, or with the specific client!
There can be 3 locations that carry configuration for the xdebug+xdebug client combination! The client(or editor plugin) configuration, the 20-xdebug-conf.ini file (or in php.ini equivalent), and your project-specific configuration. Make sure all 3 locations are in sync in terms of port, path_mapping, etc.
I am trying to configure xdebug to work in PhpStorm with my Vagrant machine, but I cannot figure out how to properly configure everything.
Here is the Vagrantfile I am using:
https://github.com/fideloper/Vaprobash
This Vagrantfile installs and configures xdebug for my Vagrant machine, but I'm not sure how to hook that up with PhpStorm. Between my xdebug.ini config, my web server config, and the PHP web app debug config, I cannot figure out how to get everything working.
When I click run->debug in PhpStorm, I get the following:
I have tried hacking away at the configuration details but have had 0 luck. Can anyone point out what I'm doing wrong here?
xdebug runs "backwards" to most typical server software one would deal with on Vagrant. IE, for apache you would fire that up on the VM and forward a port from the host to the VM so you could hit the server. Well, xdebug wants to push data from the VM to the host machine. Which means you need to feed xdebug the host's IP address -- which is probably the one the VM configured on the host only network and not your typical IP address -- and also to make sure that xdebug server is running and can accept connections.
Yeah that leaves a bit to be desired . . . .
When I develop with the server on my workstation I can use XDebug from my IDE and debug variables, etc.
Many times the server is on a remote machine where I have only SSH, so I only edit with vi. In that case is there a way to use XDebug? Is there a client I could use from terminal?
You can use X forwarding with ssh, if allowed at the server end (see the ForwardX11Trusted directive for the server's ssh configuration file). On your client you would start ssh using the -X argument to allow X forwarding. This requires the client to support X (e.g. if your local machine is running Linux, OS X, etc...)
