email – PHP mail: Multiple recipients?

Posted by: admin April 23, 2020 Leave a comment


I have this code:


$result = mysql_query("SELECT * FROM email");

while($row = mysql_fetch_array($result))
$to = $row['address'];
$subject = "Test mail";
$message = "Hello! This is a simple email message.";
$from = "[email protected]";
$headers = "From:" . $from;

In my table (“email”) I have multiple addresses.
(They are not comma sepparated.)
How could I send my message to all of those addresses?

How to&Answers:
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.


Separate the addresses with commas.

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


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


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! 🙂


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

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


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.

$emails = ['[email protected]', '[email protected]', '[email protected]'];
foreach ($emails as $email){ // or $result as $row
    $email, // or $row['address']
    'Same Subject',
    'Same Content',
    'From: [email protected]',
    '-f [email protected]'
