? actually means 0 or 1 times.
* means 0 or more times
+ means 1 or more times

As the first expression shows! The trailing i after the slash means ignore
case. The ? on the l means 0 or 1 "ell" characters (read this carefully -
one and ell look the same) and then of course this pattern must be found at
the end of the string.
