Returns successfully if tt(string) matches the previously-compiled
PCRE.
If the expression captures substrings within parentheses,
tt(pcre_match) will set the positional parameters to
those substrings, starting with $1 for the first.
tt(pcre_match) will set the array var($match) to those
substrings, unless the tt(-a) option is given, in which
case it will set the array var(arr).
