Preg Replace

[Charisma Bypass]

a-zA-Z0-9@ :{}_.-/

I need those characters to be allowed only, but am having problems with the forward slash.

here's my code:

return preg_replace("/[^a-zA-Z0-9@ :{}_.-/]/i", "", urldecode($address));

How do I make it use the forward slash and not see it as a limiter (if that makes sense).

Thanks all!

Escape the / and the - with a \

Do you really need urldecode?

jason - very many thanks, you got me out of a bind.

Is there a list of characters that should be escaped at all times?

[JasonD]

The preg_quote() manual page should have a list, although not all need escaping at all times, the {} when in [] don't, for example.

Back on this, with a slight problem.

I now need to include all the extended characters used in other languages, eg
á à ø and all the rest.  Any idea how to do that?  Been searching google fruitlessly.
Thank You in advance.

Couldn't find the manual in Google eh?

Thanks Jason - I didn't bother with that as the webpages are iso-8859-1 and the db is latin1_swedish_ci.
This appears to be utf-8 ?  I'll test it.

[a-zA-ZÀ-ÖØ-öø-ÿ]

etc. Just be sure that your php is saved as iso-8859-1 too or use the \xXX form.

If you're doing much in non-English then utf-8 would be better in the long term. If the Norwegians want to use their proper alphabet the Welsh won't be too far behind.
