Re: [PHP] Directing form to different handlers?
It would be much simpler and cleaner to use Javascript to modify the form's
action attribute onClick.

You do have a point with not all clients having Javascript. It would be a business decision on the part of Shawn if he wants to support the fraction of users running browsers without support for the most basic of extensions.

Hi,
I need to extract the first digit after the decimal point from a
number such as 28.56018, which should be '5'.
Since no one came up with the simple solution:
$num = "28.56018";
ereg("^[0-9]+\.([0-9]){1}", trim($num), $regs);
if($regs[1])
$digit = $regs[1];
else
print "no digit found";
My submission for a "simple" solution. I wish I had xslt2 =(
select="number(substring(substring-after(number(translate(normalize-space($number),translate(normalize-space($number),'.0123456789',''),'')),'.'),1,1))"/>
