Removing Non Alphanumeric Characters With PHP

Question

I need to remove all characters from a string which aren't a-z A-Z 0-9 or " ", anyone got a function to do this?

Answer 1

Sounds like you almost knew what you wanted to do already, you basically defined it as a regex.

preg_replace("/[^A-Za-z0-9 ]/", '', $string);

Answer 2

Regular expression is your answer.

$str = preg_replace('/[^a-z\d ]/i', '', $str);
