How to indicate the last indice in a PHP array?

Question

I have a simple mail() script that sends to multiple emails dynamically by seperating the emails with commas.

<?php

$sendto = array("email@gmail.com", "email@zoho.com", "email@mail.usf.edu");
foreach ($sendto as $email)
{
    if ($email is the last indice in the array..) // <-- here
        $to = $email;
    else
        $to = $email . ', ';
}

$subject = "test message";
$msg = "this is a test";

if (mail($to, $subject, $msg)) 
    echo "message sent";
else 
    echo "uh oh";
?>

How do I identify if (this is the last piece of data in my array) ?

@ColeJohnson I can help you with that - what is your current location ? :) — Nir Alfasi, Aug 15 '12 at 02:14

No need.

$to = implode(', ', $sendto);

php includes implode or join which will work much better here:

$to = implode(', ', $sendto);

Just make your if clause use the end function:

if ($email == end($sendto))

this answered my question directly and is appreciated, as are the others for the refactoring value – khaverim Aug 15 '12 at 02:26

@khanahk: Except it doesn't. `array(1, 2, 4, 2);` – Ignacio Vazquez-Abrams Aug 15 '12 at 02:30
