note 28423 added to function.is-float

Ive been trying to get a price validation working with the is_float function but as far as i know it wont work with a string input, so heres one i made which seems to do the trick. function check_valid_price($num) { if (!(eregi('^[1-9]{1}[0-9]{0,2}$',$num)) && (!(eregi('^[0-9]{1}[0-9]{0,2}[.]{1}[0-9]{2}$',$num)))) { return false; } else return true; } it accepts numbers like 1, 1.20, 0.99, but not 1.1, 1.111, 1.1., .20 -- http://www.php.net/manual/en/function.is-float.php http://master.php.net/manage/user-notes.php?action=edit+28423 http://master.php.net/manage/user-notes.php?action=delete+28423 http://master.php.net/manage/user-notes.php?action=reject+28423
