note 28817 added to function.ereg

I'm in the ski business and had to do one to verify shoe size entry. This regex will accept digits from 1 to 19 by itself, or 1 to 19 with an optional .0 or .5 on the end, it wont accept greater than 19 or .1 .4, etc. only .0 or .5 (Shoes only have half sizes). $f_value = <your shoe size>; if(!ereg('^([1]{1}[0-9]{1}|[1-9]{1})(\.[05])?$' ,$f_value)) { echo "Invalid Input"; exit; } Not that anyone will be able to use this exactly, but I found reading what other people have done helps me understand regex better. Hope this helps, Scott -- http://www.php.net/manual/en/function.ereg.php http://master.php.net/manage/user-notes.php?action=edit+28817 http://master.php.net/manage/user-notes.php?action=delete+28817 http://master.php.net/manage/user-notes.php?action=reject+28817
