What about using strpos instead of the slower preg_match?

White space characters are defined by the PCRELib as:

LF (dec 10 = hex \x0a = char "\n")
HT (dec 9 = hex \x09 = char "\t")
VT (dec 11 = hex \x0b = char "\v")
FF (dec 12 = hex \x0c = char "\f")
CR (dec 13 = hex \x0d = char "\r")
space (dec 32 = hex \x20 = char " ")
