Replacing punctuation in a string
i want to change a string to contain only alphanumeric characters and spaces, by stripping out everything else and replacing them with a space.

i think it would probably use preg_replace() but i'm having trouble writing the regex that will correctly do this.

PHP Code:
 $pattern = "/[^0-9a-z\s]/i";

preg_replace($pattern, " ", $text_to_filter); 


^ = NOT the following
0-9 = numerals zero to nine
a-z = letters a to z
\s = whitespace
i = insensitive to case
