i'm having trouble with preg_replace, how do i make it that the preg_replace replaces any characters thats not in the list of a-z,A-Z,0-9 and only allow the characters ' ', '-', '(', ')' to be entered?

Use a character set

$text = 'abcd 14-2334-8896 56"#@(55)';

$text = preg_replace('~[^a-z0-9\(\)\- ]~i', '', $text);

echo $text;
