Hello, I'm using PHP Tools for Visual Studio on VS2019. I deployed my php codes in a docker container. I setup some breakpoints in my codes and ran a debugger and I found my breakpoints were not breaking.

I checked out the xdebug log in my docker container, it seems that connection between my server and my debugger had been success established, and the breakpoints I set in my codes had been found. Here are the xdebug log in my docker container:

The Visual Studio's output window shows that 'Auto-attach to process '[pid] php_remote.exe' on machine 'machine name' succeeded.' and once a request come in, I would receive a message that php_remote.exe has exited, the return value is -1 (0xffffffff).

I tried deploy my code on my local machine, the debugger works fine. And I tried using PHP Debug extension(felixfbecker.php-debug) on vscode, it works fine with my container too.

Here are my php.ini file using by PHP Tools for Visual Studio:

    [Xdebug]
    zend_extension=C:\php\php-7.1\ext\php_xdebug.dll
    xdebug.remote_host=localhost
    xdebug.remote_port=9100
    xdebug.idekey="php-vs"
    xdebug.remote_enable = on
    xdebug.remote_handler = dbgp
    xdebug.remote_autostart = 1

Here are my launch.json when I'm using PHP Debug extension for VSCode:

        {
            "name": "Listen for XDebug",
            "type": "php",
            "request": "launch",
            "port": 9100,
            "pathMappings": {
                "/data/dev/mysite": "${workspaceRoot}"
            }
        },
