Email - Multiple Recipients.

[blackhowk]

Additional recipient emails can be added to the first variable separating them by commas, not semicolons.
$to = "yourplace@somewhere.com,firstemail@here.com";
A more advanced method is to put a newline separated email list into a text file, trim each entry, implode them into an array variable, and use the array variable as the $to value.

elist.txt
firstemail@here.com
secondemail@there.com



etc....

email.php
<?php
// read the list of emails from the file.
$email_list = file("elist.txt");

// count how many emails there are.
$total_emails = count($email_list);

// go through the list and trim off the newline character.
for ($counter=0; $counter<$total_emails; $counter++) {
$email_list[$counter] = trim($email_list[$counter]);
}

// implode the list into a single variable, put commas in, apply as $to value.
$to = implode(",",$email_list);

$subject = "My email test.";
$message = "Hello, how are you?";

if ( mail($to,$subject,$message) ) {
echo "The email has been sent!";
} else {
echo "The email has failed!";
}
?>
