Regular expression help
|

| Hi everyone
I am using a ereg_replace to strip all but certain allowed characters
from a string:
$string =3D ereg_replace("([^ 0-9A-Za-z=C5=A0=C5=92=C5=BD=C5=A1=C5=93=C5=BE=
=C5=B8=C3=80-=C3=96=C3=98-=C3=B6=C3=B8-=C3=BE-])","",$string);
I would like to extend this to allow HTML character references of the
form "&#number;" where number is the three or four digit code number
of the character. Examples would be "ä" and "ẽ".
I am sorry but regular expressions hurt my brain!
Thankyou in advance
Karin

use preg. read the manual for an explanation.

as well as reading the manual. ;^) were you to have, you'd notice that you
would have been instructed to use preg rather than ereg for a miriad of
reasons. not only that, but you'd see an example of preg_replace doing
*exactly* what you're asking help on.
if regex hurts your brain, don't use it...you won't be able to maintain it
once you initially write it. it is a language in itself.
