For first part warning, there is no smtp server in your system. In order to send mail SMTP server needed to be installed or if you use a different smtp server instead of localhost smtp server.

For the second warning:
You are trying to set cookie or trying to set header information after sending any data to client. When you first send any data(even a single white space is a data) php finish sending header and start sending data. but if you send header after sending data then you will get this warning
