I would recommend using \\s instead of \s -- While \s doesn't have any
meaning in PHP strings, so PHP just figures you must have meant \\s

Does $single have a "#" character in it by any chance???
Ooooh. Or does $total sometimes have "/#" in it?
Imagine that $total has "#/#" in it.
Then your PRCE string turns into:
"/Charges \s\s+ #/# x (.+) /siU"
v--------^
Preg "sees" this / to end the search string, and then it sees a #
after that, and thinks you are trying to use # the way you are using
"siU" at the end.
Only # ain't a valid character in that location.
