Im having problems with a regex. I am trying to do a preg_replace on a
string using a regular expression which replaces a non A-Z, a-z, 0-9
character with "" (empty string" . In other words i just want to
remove all non A-Z, a-z and 0-9 characters. However spaces are ok.

Quoted text here. Click to load it

$string = preg_replace('/[^a-z0-9 ]/i','',$string);

Allthough, depending on the exact yse, you might be better served with:
$string = preg_replace('/[^\w ]/i','',$string);

 From the manual about '\w':
"A "word" character is any letter or digit or the underscore character, =

that is, any character which can be part of a Perl "word". The definitio=
n  =

of letters and digits is controlled by PCRE's character tables, and may =

vary if locale-specific matching is taking place. For example, in the "f=
r"  =

(French) locale, some character codes greater than 128 are used for  =

accented letters, and these are matched by \w."
