You could use str_replace(). I don't think you'll need the power of regular expressions, so str_replace will give you more speed.

example:

PHP Code:


$replace = array(
    // array(OUT, IN),
    array('[', ''),
    array(']', ''),
    array('.', '_'),
    array(' ', '_')
    );

$string = str_replace($replace[0], $replace[1], $string);
