Suppose I send an array of emails. The emails is an array containing john@test.com, tom@test.com, jerry@test.com....etc

From the receiving side I am trying retrieve the emails.

   foreach ($_POST['emails'] as $i => $value) {
    echo "emails[$i] is $value<br />";
    }

Is this the correct way to do it? for the foreach loop, would it iterate until all the data out of emails array finished?

    You probably could've tried this in less time than it took to post the question... – ceejayoz May 10 '12 at 20:50

That is correct. You can probably use a more simple loop though:

foreach ($_POST['emails'] as $email) {
    echo $email, "<br>";
}

Be sure to sanitize your inputs !

If you're calling an email-sending function or something, you can use array_walk().

function send_mail($email){
    echo "Sending email to {$email}";
}

array_walk($_POST['emails'], 'send_mail');

# Sending email to john@test.com
# Sending email to tom@test.com
# Sending email to jerry@test.com
# ...

Try

foreach ( $_POST ['emails'] as $value ) {
    echo $value , "<br />";
}

Just use $value:

foreach($_POST['emails'] as $value) {
    echo "Email: {$value}\n";
}

Or you can also use the array key to access the value, but there's no point if you don't want to edit values:

foreach($_POST['emails'] as $key => $value) {
    echo "Email: " . $_POST['emails'][$key];
}

No, you use that syntax for associative arrays, $_POST['emails'] is most likely, not an associative array. The correct way would be something like this instead:

foreach ($_POST['emails'] as $email) {
echo "Email: $email<br />";
}
