Example Application: PHP Debugging

This repository is an example of how to get basic debugging running with XDebug, and the oberd/alpine-apache:7.2-dev image.

Installation (VSCode)

Example configuration (.vscode/launch.json)

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Listen for XDebug",
            "type": "php",
            "request": "launch",
            "port": 9000,
            "pathMappings": {
                "/var/www/app": "${workspaceRoot}"
            }
        }
    ]
}

Running this example website (VSCode)

1. Start the application by running docker-compose up in a terminal
2. Click on the "Debug" icon on the left hand menu, and click the play button icon "Start Debugging" (You can also start debugging using cmd+option+shift+d).
3. Visit the application at http://10.45.1.100:7000 (IP may vary based on your docker configuration)

Upon loading the page, you should be taken to the VSCode Debug Panel, with paused execution inside of the "throw_error()" function.

Play around with the debugger and get a feel for the variables, stack tracing, stepping functionality, and console.

Running the example CLI program (VSCode)
