Debug isn't working

Hi all,
I've been running IM through PHP using the exec() command as I am on shared hosting.
Now, I'm currently trying to get '-debug all' to work, but no matter what I do, I don't get anything back. Nothing. I am trying to use this in conjuction with an image cropper and this is why I need to see the debug logs so I can at least see where it's failing.
Is there something that can prevent -debug outputting it's logs? This is the exec I am using (note the cropping parameter is left out):
Code: Select all
exec(convert -debug all images/site_content/approved_stamp.jpg images/site_content/approved_stamp22.tiff);
I've lost a day on trying to get -debug to work, but to no avail! Please, please does anyone know why I'm not getting any debug logs or output?
Thank you!

Debug output goes to stderr, not stdout. Are you reading the correct channel?

This is going to sound incredibly n00bish, but stderr, would that be my general error_log.txt file, that generates whenever there is a php error. Like "Undefined Variable" etc, or is stderr different? If so, how can I read the stderr channel?
Also, thank you graciously for your fast reply!
EDIT: I think I have it: at the end of my exec() call, I added this: '2>&1' and I'm getting this outputted now:
Code: Select all
convert -debug all images/site_content/approved_stamp.jpg images/site_content/approved_stamp22.tiff 2>&1

I'm assuming I've now got the debugging logs working?

Sorry, I don't know PHP, but it would be something like:
Code: Select all
exec("convert -debug all images/site_content/approved_stamp.jpg images/site_content/approved_stamp22.tiff 2>&1", $err_output);
