preg_replace(
array('` {2,}`',"`[$specials]+`"),
array(' ',''),
$subject)

| Try this simple yet powerfull solution
//Your String
$string = "a&*bbb cc/c d!d";
//Array of special charecters you want to replace
$special = array('/','!','&','*'); //here you can add as many char. you
want
$replacements = "";
echo str_replace($special,'',$string);

That still doesn't remove multiple spaces, ie. whitespace. Some regexp
wizard kid could tell how the whitespace is replaced with a single space.
I'd say that converting the spcial chars would be easy too with regular
expressions.
The thing is I'm all thumbs with regexp so I can only recommend using it but
I have no idea how it would work ;)

My feeling is KIS (Keep It Simple).
Try this:
<?php
$str = 'a&*bbb cc/c d!d';
$special = array('/','!','&','*');
$str = str_replace(' ',' ',str_replace($special,'',$str));
//
// first remove all the special characters
// then replace all consecutive two spaces with one space
//
echo '['.$str.']';
?>

| So Im further right now, I need to put the hole ASCII table in de $special
except :
A..Z (0x41 0x5A
a..z (0x61..0x7A
0..9 (0x30..0x39)
space (0x20)
À..? (0xC0..0x259)?!?
Is there a better way to do this?

I use this for foldernames:
Not sure about alnum in the third one, if it allows foreign (to us in
the states) characters.
// clean up the user specified foldername
$foldername =3D stripslashes ( $_POST['foldername'] );
//This erase white-spaces on the beginning and the end in each line of
a string:
$foldername =3D preg_replace('~^(\s*)(.*?)(\s*)$~m', "\\2", $foldername);
//erases all NON-alfanumerics
$foldername =3D ereg_replace("[^[:alnum:] ]","",$foldername);
// take out repetative spaces:
$foldername =3D preg_replace('/\s\s+/', ' ', $foldername);
if ($foldername =3D=3D ""){$foldername =3D "untitled";}
