you don't make it clear about what doesn't work
but here is a guess: you are getting match=1 in all cases (or at least
all where strvar is not missing); remember, however, that strpos=0 if
"S" is not found; so, in addition to the quotes, etc., I guess you want
to ensure that strpos is >0 (and maybe <.)
