Should the .+ be a \w+ so as to not jump words?

$str = 'bart is a fool qux';
[download]

will not replace 'foo'.

I guess that depends upon whether the OP is actually using the terms 'foo', 'bar' and 'qux', or whether they are just placeholders for the purpose of his question? Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal? "Science is about questioning the status quo. Questioning authority". The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.
