Since you are dropping out of the PHP context into the native shell, you are going to have a lot of issues debugging.

The best and most foolproof I have used in the past is writing the output of the script to a log file and tailing it during PHP execution.

 ~/debug.log 2>&1");

Then in a separate shell:

tail -200f ~/debug.log

When you execute your PHP script, your errors and output from your shell call will display in your debug.log file.
