How to get an variable displayed for debugging purposes?

[Dolfijn]

It's a long time that I debugged PHP. I would like to do so to better understand what I'm doing wrong (as I often do 🙂). I'm  running in production at a hosting provider. I will only use it to analyse  backoffice code.

I  already switched debugging on and also did so in defines.inc.php. But a simple echo('Hello'); is never seen..?

How can I do this in TB 1.5?

I finally opened a file and wrote  some php %variables to file. It works..

$file = fopen(_PS_ROOT_DIR_ . '/myLog1.txt', 'a');
 $my_own_message = strval($idShop);
 fwrite($file, $my_own_message);
 fclose($file);
