Re: Re: Substr by words

Hello, Marcus. No, you are right. Your script is better. I just forgot something I learned about REGEXES: The REGEX engine is eager. Thus, in this case, It's not necessary to use the caret. The REGEX engine will start from the first word It finds. I would use yours ;-). Best regards, Gustavo Narea. PHP Documentation - Spanish Translation Team. Valencia, Venezuela. Marcus Bointon wrote:

I think It is OK what I said about the caret, but what we need to change is the position of \W*: Your suggestion: /(\b\w+\b\W*){1,$MaxWords}/ My suggestion: /^(\W*\b\w+\b){1,$MaxWords}/ We need the *first* ($MaxWords)th words.

I makes no difference - they will both work. Mine doesn't care where the first word starts because it doesn't use ^, and yours doesn't care where the first word starts because it's got ^ followed by \W*. Your overall match will end up with leading spaces, mine will end up with trailing spaces - the subsequent trim fixes them both. I like mine because it has 1 less char ;^) Ultimately, if it works for you, great! Marcus
