why are you exploding an array? $emails is already an array and can
already be accessed via index i.e. $emails[0..n];

and similar to what adam metioned, i don't even know what would happen
when you explode an array so your unexpected results are, well,
expected. ;)

$emails =
array("[EMAIL PROTECTED]","[EMAIL PROTECTED]",[EMAIL PROTECTED]);
$emails_cnt = count($addresses);

for ($i = 0; $i < $emails_cnt; $i++)
{
  echo "$i:{$emails[$i]}";

  if ($i == ($emails_cnt - 1))
  {
$form['recipient'] .= $emails[$i];
  }
  else
  {
$form['recipient'] .= $emails[$i] . ',';
  }
}

echo "Recipient = {$form['recipient']}";


maybe that will work? (untested)


chris.

p.s. from now on don't use the count() function within loops (including
the loop declaration) because it slows things way down (when you count
the same variable over and over). instead do like what i did, count it
ahead of time and then just reference the answer.

You need to look up how to use explode[1], my guess is you don't want to
use it at all here.  In fact, implode[2] may be exactly what you are
looking for.

If you want to see the contents of an array, use the print_r function:

HTH!

[PHP] What's wrong with this code please?

[Donpro]

$emails = array("[EMAIL PROTECTED]","[EMAIL PROTECTED]",[EMAIL PROTECTED]);
$addresses = explode(",",$emails);
for ($i=0; $i < count($addresses); $i++) {
   echo $i . ': ' . $addresses[$i] . '';
   if ($i == count($addresses) - 1)
  $form['recipient'] .= $addresses[$i];
   else
  $form['recipient'] .= $addresses[$i] . ',';
   }
   echo 'Recipient = ' . $form['recipient'] . '';

 
The output I am receiving is:
0: Array
Recipient = Array
 
Obviously, I want to see the output of each array element as well as the
final contents of $form['recipient'].
 
Thanks in advance,
Don
