Ensure docker development easy works with xdebug and vscode

[benmarte]

Describe the problem

Fix xdebug settings in php.ini or 50_xdebug.ini in the openemr/openemr:flex docker image.

Describe the solution you'd like

We need to add these 2 lines of code to either php.ini in /etc/php7/ where the current xdebug config settings are in or in the 50_xdebug.ini file in /etc/php7/conf.d/

xdebug.client_host=host.docker.internal
xdebug.mode=debug

VSCode users would then need to create a launch.json file with the following code:

{
    // 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": 9003,
        "externalConsole": false,
        "log": true,
        "pathMappings": {
          "/var/www/localhost/htdocs/openemr": "${workspaceRoot}"
        },
        "ignore": [
          "**/vendor/**/*.php"
        ]      
      },
      {
        "name": "Launch currently open script",
        "type": "php",
        "request": "launch",
        "program": "${file}",
        "cwd": "${fileDirname}",
        "port": 9000
    }
    ]
  }

After installing PHP Debug plugin

@bradymiller suggests below launch.json for "production" development :)

{
  // 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": 9003,
      "pathMappings": {
        "/var/www/localhost/htdocs/openemr": "${workspaceFolder}"
      },
      "ignore": [
        "**/vendor/**/*.php"
      ]      
    },
    {
      "name": "Launch currently open script",
      "type": "php",
      "request": "launch",
      "program": "${file}",
      "cwd": "${fileDirname}",
      "port": 9003
    }
  ]
}
