Webhook – problem

Hi, needing to update the warehouse of an external database, I created a webhook to a php script.

However, I cannot extrapolate the data of the “line_items” array, following your tree as per attachment.

I do a for loop like this but the data is not returned:

$ data = file_get_contents (“php: // input”);
$ events = json_decode ($ data, true);

foreach ($ events [‘line_items’] [0] [‘sku’] as $ array_result) {

echo $ array_result;

}

What am I doing wrong?
