PHP mail: Multiple recipients?

Question

I have this code:

Answer 1

I just tested the codes you presented and before using them, people need to know that using this way (multiple addresses in 'to' field), every single person in that email can see all the destinatars.

Also, if you're using Bcc, they'll also know the first person in the list.

Be aware! :)

Answer 2

According to Alex's answer above, recipients will know the first person in the list even if you're using BCC. A solution for this would be to send individual copies to each address one by one.

$emails = ['a@example.com', 'b@example.com', 'c@example.com'];
foreach ($emails as $email){ // or $result as $row
  mail(
    $email, // or $row['address']
    'Same Subject',
    'Same Content',
    'From: same_sender@example.com',
    '-f same_sender@example.com'
  );
}

Answer 3

while($row = mysql_fetch_array($result))
{
    $addresses[] = $row['address'];
}
$to = implode(", ", $addresses);

As specified on the mail() manual page, the "to" parameter of the function can take a comma-separated list of addresses.

Answer 4

You just need to use GROUP_CONCAT to return the results separated by ','

$result = mysql_query("SELECT GROUP_CONCAT(address) FROM email");

Answer 5

Separate the addresses with commas.

$to=array();
while($row = mysql_fetch_array($result)) {
    array_push($to, $row['address']);
}

...

mail(implode(',', $to), $submit, $message, $headers);
