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);

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.. > > > On Tuesday 15 May 2001 22:35, Gyozo Papp wrote: > > I mean that it seems to me most of the mailers use preg funtions > > instead of simple ereg functions.

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.

No, now it's time to get familiar with the online manual
, where you would quickly discover that
preg_quote can be used even by somone with zero knowledge of PCRE syntax.

RE: [PHP] still not friends with RegExps..
If you intend on using regex's intensively (or at all really) do yourself a
favor and get mastering regular expressions from o'reilly...it has more than
you'll probably care to know at first, but so many good examples, and such a
detailed analysis, that you'll become really comfortable and won't playing
the guessing that i for one used to...

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.

Forget quotemeta(). Use preg_quote() instead.

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?

RE: [PHP] still not friends with RegExps..
preg_replace does not seem to agree with '\\'.
Below seems to work with ereg_replace.

Hello,
Maybe RegExps are still my point of weakness...but I still like them as much
as I like the Self-Reference phrases...
Okay now, how can i replace all the matches of "\" , "*", "+", "-" and ";"
with an empty string by calling once the preg_replace() or str_replace() or
any string replace function? ("")
Do i have to call it as many times as i got different replacments?

$string = preg_replace("/[\\\*\+\-;]/s","",$string);
I think, you might have to escape the ; too
