RE: reg exp to filter bad characters in filename

Not sure about Perl syntax (i use js regExp), but the special pattern '\w'
matches only letters, numbers, or underscores.

HTH.

I would also be interested in something like this.  Unfortunately, all I
have gotten around to writing is renaming the file in case one with the
same name already exists.

Yo

I wrote a PHP app to allow people to upload files.  Immediately the
client
proceeds to upload files with all kinds of gunk in them, such as '+'
and ' '.

I need a reg exp to filter out everything but alphanumeric, ., and _
characters.  I could do a nested if statement or something but I know
there's a nice terse Perl compatible solution.

Thanks!
