When debugging in PHP and using the variables pane on the left, there is a limit to the amount of characters you can see for that variable/object when hovering over.
Is there anyway to see the full payload for that variable or any work around other than having to use file_put_contents every time I want to see a large variable value? Also printing the variable to the debug console has the same limitation but adds one extra character (lucky me).
In order to achieve that you need to make a change in your launch.json configuration of xdebug in VS Code.
The piece of configuration you will need to add to your configuration of launch.json is "xdebugSettings": { "max_data": -1 }
A simple configuration should look like that
{
"version": "0.2.0",
"configurations": [
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9000,
"serverSourceRoot": "/var/www/myapp/",
"localSourceRoot": "${workspaceRoot}/",
"xdebugSettings": {
"max_data": -1
}
}]
}
xdebugSettings.max_data
Controls the maximum string length that is shown when variables are displayed. To disable any limitation, use -1 as value.
Good luck.
-1 will remove any limitation and that could slow down when debugging huge variables. So choosing an arbitrary number would improve speed. A smaller number means better performance as xDebug doesn't have to present any variable that is huge. It will cut it's content to the size you have specified by the arbitrary number.
