send multiple emails comma separated

[eluser]PHP Programmer[/eluser]
I have a textbox which can contain 5 different emails (comma separated). I am using the mail send() function of the codeigniter but what it does is sending the mail to the email id that is written at the very first place in that textbox. How can I manage the mail to be sent to other email ids?

Please suggest..

TIA

Straight from the manual...

Code:

$this->email->to()

Sets the email address(s) of the recipient(s). Can be a single email, a comma-delimited list or an array:

Code:

$this->email->to('[email protected]');
$this->email->to('[email protected], [email protected], [email protected]');

Code:

$list = array('[email protected]', '[email protected]', '[email protected]');
$this->email->to($list);
