This is an illustration of how to send email through PHP. I did not create a function because I feel mail() is already a wrapper all by itself. I left the first parameter empty because I feel that the "to row" is not any more important than any other row in the header string.

Multiple email addresses entered into any of the header fields (to, cc, bcc) must be separated by a semicolon (;). Also, email addresses may be entered as "name <email_address>".
