Sending Form to more than 1 email address

[crumpy1]

Hi All,

 

I have a form on my website which when submitted comes through to me. However i would like to send this to the sender also.

 

This is my code currently that processes where things are sent to.

 

//
$to='admin@localhost';
//
$subjectline='Web site form - Contact Us'; //

 

I have researched how to do this if you know the persons email address so it would be $to='[email protected] , [email protected] , [email protected]'; however the address will change depending on what my sender puts in the email address field 'email' but don't know how this is coded.

 

is $to='admin@localhost, email'; the correct way of coding this?

 

Thanks
