Hi, all --
I would like to make things easier for my users and replace all of the garbage characters
`'";:[EMAIL PROTECTED]&*()[]{}<>/?\|+=
plus white space (\s) with underscores in the input. I am, however, having trouble getting my regexp to work.
I can comfortably do
$i = preg_replace("/[\s]/","_",$i) ;
but trying to add other chars doesn't do a thing.
I want to end up with
A-Za-z0-9_-
(letters, numbers, underscore and dash).
If there isn't a handy character class waiting for me, what must I do to get those chars replaced?
TIA & HAND
:-D
$i = preg_replace('/[^A-Za-z0-9_-]/', '_', $i);
That means anything that is not in that class should be replaced with '_'.
