Question

I would like to be able to get an array of emails and make sure each email is sent. (e.g. Array > send each email > result) I kind of changed the question here because this is more important, plus I have added a 50 rep. point. Codewise how can I do this?

Answer 1

If you just want to send out a bunch of the same email at once, you
could call implode() on your array of emails to turn it into a string:

$to_string = implode(', ', $to_array);

Or, if you want to try something more complicated, you could use a
foreach loop to cycle through each email and to keep track of
successes and failures:

$success = array();
$failure = array();

foreach ($to_array as $to_email)
{
  if (mail($to_email, $subject, $message, ...))
    $success[] = $to_email;
  else
    $failure[] = $to_email;
}

I’m guessing your original question had to do with sending out all these
emails every day or something without necessitating you hitting a
button. If you have ssh access, see what happens if you type:

crontab -e

If you get some sort of error, you will have to speak with your system
administrator about cron. If you get a file, then you can use cron. This
is not a part of your current question, though, so I’ll leave it.
