Off teeh top of my novice head I think count() or sizeof() is what your
looking for.

 Subject: [PHP] assoc array question


 I have this: (note that $info is an Assoc Array

 while (list ($key, $val) = each ($info))
   {
do stuff
   }

 I would like to do slightly different stuff if I'm at the very first, or
 very last item in the array.  How do I do this.  Below is the pseudo code
 which would be ideal:

 while (list ($key, $val) = each ($info))
   {
 if(onFirstKey or onLastKey)
   do fun stuff
else
   do other stuff
   }

 Please help.  Thanks

  while (list ($key, $val) = each ($info))
{
 do stuff
}

$count = 0;
$last = sizeof($info);

While (list($key, $val) = each($info))
{
  if ($count == 0)
  {
// first time through
  }
  if ($count == $last)
  {
// last time through
  }
  // do stuff
  $count++;
}
