How to send email
Project : in this project you will learn how to send email using php method.
We have to make some configuration setting in php.ini in xampp
To send email we need to have SMTP, We can buy SMTP online or we can use GMAIL SMTP for sending email.
When you click on button "SendEmail" email will be sent on live host ! Not on you localhost
If you try to send email on localhost ! It give a warning
Warning: mail(): Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in
To fix this problem you have to add some configurarion in xampp file php.ini
SMTP=smtp.gmail.com smtp_port=25 sendmail_from = yourgmailaccount@gmail.com auth_password=Your-Gmail-Passwordindex
