If you want full control, use proc_open/proc_close. proc_close() will give you
the exit code or you can write $? to one of the streams to get a more accurate
one. I suppose you could also do something intelligent with $? on the
shell_exec() command, but that is more of a hack. All these exec() functions
simply apply different levels of filtering and usability on top of the low-level
proc_open() call. If it isn't doing what you want drop down a level and implement
what you need. There are plenty of cases where you want \r\n and all other
whitespace stripped from the end of lines.

With regard to the need for a delimiter, I guess that, like Arne, I'm wondering why we
couldn't just use the newline character for that purpose.

If I use shell_exec(), is there any way to get the exit code?

If you want the raw unaltered output from the command use shell_exec() not
exec(). By definition exec() has to use a delimiter in order to create the array.
If you don't want it to do that, just grab the raw via shell_exec() and do your
own parsing.

I've just run into this "feature", writing a tool that needs to be able to read in a
file from a given commit repo. Because of the "feature", every line in the resulting file
is stripped of trailing whitespace, creating a lot of spurious diffs.
I am at a loss to see the motivation for this behavior. Information is being discarded, with no
possibility of recovering it. The only workaround I can think of is to
1. Use sed, or a comparable utility, to add a non-whitespace character to the end of every line
2. Make the PHP exec() call
3. In PHP, strip the spurious character from the end of each line.
Please put in the extra flag to turn this behavior off.
