uhhh...bullshit. first, there is no need. second, you assume you know what
he wants based on the test string. be logical! his string may very well be
'a1ba2ba3b'. if he becomes more specific with us about what he wants, THEN
you'll be able to make such leaps...and be a bit more accurate. your 'better
solution' is tripe. as others have pointed out:
preg_replace('/a.*?b/', 'peter', 'a1ba2ba3b');
with heavy emphasis on PREG...THAT is the only solution warranting
attention.
you seem to think coffee helps you out. i recommend you go make two or three
more pots.
