grouping an array

[nobertos]

Hi,

I need to do some mass emailing.

I have an array $unique_emails of 6,400 or so user's email addresses (the number will change as time goes by).

Putting all 6,400 email addresses into bcc: and sending with mail() seems like it wouldn't work.

I'd like to do it in groups of possibly 100 or 500 or something, by putting a string of the first 100 into the bcc: field and sending using mail().

How do I loop through the array correctly?

sort of like this, but with the correct parameters to do 100 at a time:
for ($i = 0; $i < 99 $i++ ) {

gather first 100, put in $o_address string like [e-mail], [e-mail], [e-mail]

$headers = "From: $from_address\r\n";
$headers .= "Bcc: $to_address\r\n";
mail($to, $subject, $message, $headers);
}

Thanks!

$chunks = array_chunk ($unique_emails, 100);

foreach ($chunks as $value)
{
	$to = '[e-mail]';
	$subject = 'This is the subject';
	$message = 'This is the message';
	$headers = "From: [email][e-mail][/email]\r\n";
	$headers .= 'Bcc: ' . implode (',', $value) . "\r\n";
	mail ($to, $subject, $message, $headers);	
}
