Xdebug - Debug adapter process has terminated unexpectedly - php

Question

I am using Visual Studio Code:
I have also installed the PHP Debug Extension Version 1.12.1. My PHP Version is:
>php --version
PHP 7.1.8 (cli) (built: Aug 1 2017 21:10:46) ( ZTS MSVC14 (Visual C++ 2015) x86 )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies
with Xdebug v2.5.5, Copyright (c) 2002-2017, by Derick Rethans
I have configured xdebug following the instructions on the PHP Debug plugin.
My settings inside my php.ini look like the following:
zend_extension = "C:\xampp\php\ext\php_xdebug-2.5.5-7.1-vc14.dll"
[XDebug]
xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.remote_connect_back = 1
xdebug.idekey = "whatever"
When running phpinfo(); my xdebug shows correctly:
My launch.json file looks the following:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9000
},
{
"name": "Launch currently open script",
"type": "php",
"request": "launch",
"program": "${file}",
"cwd": "${fileDirname}",
"port": 9000
}
]
}
However, when running the configuration I get:
The error log looks like the following:
messageService.ts:126 Debug adapter process has terminated unexpectedly
e.doShow # messageService.ts:126
e.show # messageService.ts:105
_.onServerExit # rawDebugSession.ts:535
(anonymous) # rawDebugSession.ts:449
emitTwo # events.js:111
emit # events.js:194
__dirname.ChildProcess._handle.onexit # internal/child_process.js:215
Any suggestions what might be wrong with debugging?
I appreciate your replies!

Answer 1

Your vscode config looks fine (at least for pure-Windows PHP debugging). Your php.ini Xdebug config is unnecessarily filled with unimportant stuff (at least for debugging).
Get rid of the whole thing and try this minimal xdebug config:
[XDebug]
xdebug.remote_enable = 1
xdebug.remote_autostart = 0
xdebug.remote_connect_back = 1
xdebug.idekey = "whatever"
Then (if you use Chrome) you can use this extension to manage enabling/disabling debug sessions: Xdebug helper
Note: This is for debugging via browser - Chrome. I guess some equivalent plugin should exist for Firefox, but I haven't tried that. If you use Linux or WSL on Windows 10, you can enable debugging session by setting the proper environment variable like export XDEBUG_CONFIG="idekey=whatever" in Linux terminal. I suppose some equivalent exists with pure Windows command-line, but I haven't tried that, either.
