Question 2

The & is causing your command to fail as it has special meaning in shell. Use escapeshellarg() to escape those characters first.

Question 3

Use escapeshellarg() to escape parameters before passing them to the command line.

This is also mandatory when passing external data (e.g. user input) as parameters.
