PHP Remote Debug Proxy setup

Installation

Install extension

You need to install the PHP Debug Extension in Visual Studio /Codium.

You can get all the relevant settings from here:

https://github.com/xdebug/vscode-php-debug

My test server is on 192.168.10.1

Install web server xdebug extension

Make sure you have xdebug installed and loaded on your webserver first. Set these in your php.ini file.

[Debugger]
xdebug.remote_enable                   = true
xdebug.remote_host                     = 127.0.0.1
; Think this is required
xdebug.remote_mode                     = req
; Check the defaults
;xdebug.remote_port                     = 9000
; not sure if this wil log - probably but I don't use it
;xdebug.remote_log                      = /var/log/xdebug.log

Install your debug proxy client

Get a remote debug proxy - this is the Active state version that I am using. I think it is bundled here:

https://www.activestate.com/products/komodo-ide/download-ide/

Or just the Debug package here:

https://code.activestate.com/komodo/remotedebugging/

Setup Visual Studio/ Codium

Here is the debug setup that I am using in Codium. Go to Run and Debug and set this up as launch.json

Name can be any name for your config. Key is your key that you register with.

    "version": "0.2.0",
    "configurations": [
        {
            "name": "vscphpdebug",
            "type": "php",
            "request": "launch",
            "stopOnEntry": true,
            "proxy": {
                "enable": true,
                "host": "192.168.10.1",
                "port": 9001,
                "key": "myvsc",
                "allowMultipleSessions": true
            },
            "pathMappings": {
                "/remote/server/directory": "${workspaceFolder}"
            },
        },
    ]
}

Save the JSON file.

Run the debug proxy on the server

Next run your debug proxy on your webserver

#!/bin/sh
python /root/dbgp/bin/pydbgpproxy -d 127.0.0.1:9000 -i 192.168.10.1:9001 -l DEBUG

Connect the client to the server

Now in VS/Codium you can see a green run button next to "vscphpdebug". Click it or press F5 and it will connect to the server - you should get a registration message

Registering myvsc on port 9003 with proxy @ 192.168.10.1:9001

Registration successful

Start debugging

Now run your code from Firefox - no extensions required

https://192.168.10.1/zTest.php?XDEBUG_SESSION_START=myvsc

Or alternatively from the server command line:

php -f ./zTest.php?XDEBUG_SESSION_START=myvsc

Other users

Another user can use their own key and connect their own instance to the same webserver. Just use a different user key in the launch.json

Stop the connection

To stop the connection use Shift + F5

Tips

If you are debugging a API file to a website you can add the XDEBUG part to a call and that will then trigger debugging on the web app as well eg:

$curl      = new Curl();
$url = "https://192.168.10.1/webapp/index.php?XDEBUG_SESSION_START=users";

$post_data = array(
  'username' => 'admin',
  'password' => 'password'
  'data' = > 'some data'
  );
  
$curl->post($url, $post_data);
