You can use the PHP built-in mail() function for sending emails to one or more recipients dynamically from your PHP app either in a plain-text form or formatted HTML.

The basic syntax of the mail() function is as follows;

mail(to, subject, message, headers, parameters)

Easiest way to send emails from php

<?php
    $to = 'xyz@somedomain.com';
    $subject = 'This is subject';
    $message = 'This is email message'; 
    $from = 'sendermailadd@email.com';

    // Sending email
    if(mail($to, $subject, $message)){
        echo 'Your mail has been sent successfully.';
    } else{
        echo 'Unable to send email. Please try again.';
    }
?>

Please note that the PHP mail() function is a part of the PHP core but you need to set up a mail server on your machine to make it really work.
