Yet Another PHP REG EXP Q?
I hate to ask you guys b/c I know it gets you angry when people ask for reg exp help...hehe..I swear i'll take to the time to learn it myself in the next few days..but for now I need some quick help.
I need a way to strip out all characters except these _-[a-zA-Z0-9]
Using one of the php reg exp...i guess using the preg_replace or something similar.
Thanks,
Dave

Why do you say that reg expression are usualy challenging
preg_replace("/\W/","//",$mystring);IF , ELSE , WHILE isn't that what life is all about

Well people normally just scuff and say learn it yourself.
\W
Matches any non-alphanumeric character; this is equivalent to the class [^a-zA-Z0-9_].
How would I go about adding - to this set of charactes. You forgot I had that in the list.

I just need to take the time and learn this stuff...I haven't spent one second reading the documentation. I'm sure it won't take that long for me to learn it... Thanks again

fyi: leran the perl shorts. they're notrmally quite helpful. and \w is the opposite of \W ... like \d and \D are opposites and \s and \S are opposites
POSIX. because a stable os that doesn't have memory leaks and isn't buggy is always good.
