I get response content in blank

i am getting a blank result in label from the response content. i dont know why if my code is ok

Yet another php forum question !

Your php code is written to return data to a web page.

You need to echo only once for the web component:

echo "[" . $datos1 . "," . $datos2 . "," . $datos3 . "]"

In your blocks , use the jsonTextdecode block to convert the responseContent to an AI2 list, then iterate over that list to set the values to the labels.
