回答1:
Your mail format is wrong
mail($email_address,$subject,$msg,$header);

To send email using localhost you need to configure localhost to send emails.
The followings steps are to send email using localhost with xampp and sendmail
You can send mail from localhost with sendmail package , sendmail package is inbuild in XAMPP. So if you are using XAMPP then you can easily send mail from localhost.
for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.
in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.
in php.ini file find [mail function] and change
SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = my-gmail-id@gmail.com
sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"
Replace all the existing code in sendmail.ini with following code
smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
auth_username=your-gmail-id@gmail.com
auth_password=your-gmail-password
force_sender=your-gmail-id@gmail.com
Then you are done :)
remember to restart the server using the XAMMP control panel so the changes take effect. Happy coding :)
By the way your mail function is incorrect
it should be
mail($to,$subject,$message,$headers);
