Two more advantages of using `shell_exec()`:

- you can override/mock `shell_exec()` in a namespace. You cannot do that 
with the "backtick operator".
- in IDEs like PHPStorm, you can ctrl-click on the function name 
"shell_exec" to check what it does: see what the return value is, see a 
description, click the link to the manual. You can easily search for 
"other usages" (right-click "Find Usages"). You cannot do that with the 
"backtick operator".
