When this happens to me I always just echo the variable value like so to see if something is there that shouldn't be:
echo "cccc"; echo "$id"; echo "cccc"; obviously all this does is print the variable with a bunch of c's before and after. That way I can see if there are any extra things included with the value that shouldn't be there. Then use the trim() commands as someone else mentioned.
