Re: [PHP] still not friends with RegExps..
Previously, Zef Hemel said: $string = preg_replace(/[\\\*\+\-;]/s,,$string); I think, you might have to escape the ; too You don't need to escape * or + inside a character class since they don't have a special meaning inside a character class. You will need to use '' to match a backslash, however. And if you move the hypen to the last position in the character class, it loses its magic property as a range specifier and no longer needs to be quoted either. This should do what you want: $string = preg_replace(/[;*+-]/s, , $string); -dan -- The process for understanding customers primarily involves sitting around with other marketing people and talking about what you would to if you were dumb enough to be a customer. -Scott Adams, The Dilbert Principle -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
RE: [PHP] still not friends with RegExps..
yes... i agree. if you know pregs, you have the added benefit of knowing how to write regexps for PHP *and* perl (should you ever have to program in perl) i personally prefer pregs becuase i think that the syntax is cleaner and more concise... -Original Message- From: Christian Reiniger [mailto:[EMAIL PROTECTED]] Subject: Re: [PHP] still not friends with RegExps..

Re: [PHP] still not friends with RegExps..
Hello, while I was reading the post from 'elias', a fairly old question came in my mind which I've not get any answer yet. Maybe you can do it. There is a function quotemeta() which escapes all special regexp character such as: . \ + * ? [ ^ ] ( $ ) with a '\' except one the '|' pipe. what reason for this behaviour? - Original Message - From: Taylor, Stewart [EMAIL PROTECTED] To: 'elias' [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: 2001. május 15. 15:16 Subject: RE: [PHP] still not friends with RegExps.. preg_replace does not seem to agree with '\\'.

Re: [PHP] still not friends with RegExps..
Ok, now it's time to get familiar with preg? If this stands, can you give me a link to a good tutorial with tons of examples beside the PHP manual? The most effective way to learn is to see how it works, I think. - Original Message - From: CC Zona [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: 2001. május 15. 21:43 Subject: Re: [PHP] still not friends with RegExps..

Re: [PHP] still not friends with RegExps..
I mean that it seems to me most of the mailers use preg funtions instead of simple ereg functions. Up to now I used only the latter ones. I still know where I can find documantation, I just go further and ask some link to learn more about PCRE functions. I'm sorry if you misunderstand it. - Original Message - From: CC Zona [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: 2001. május 15. 22:19 Subject: Re: [PHP] still not friends with RegExps..

No, now it's time to get familiar with the online manual http://php.net/pgre-quote, where you would quickly discover that preg_quote can be used even by somone with zero knowledge of PCRE syntax. -- CC -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
