how to set sender mail id for phpmailer - php

Question

my name is Milind. I trying to use PHPmailer for send mail. I mention set form in phpmailer like this:
$mail->setFrom('from#example.com', 'Mailer');
but when I received mail I get username id where I set in phpmailer
$mail->Username = 'xxx#gmail.com';
What can i do to display setfrom id to recipient
my phpmailer code follow:
<?php
// Import PHPMailer classes into the global namespace
// These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require 'PHPMailer/src/Exception.php';
require 'PHPMailer/src/PHPMailer.php';
require 'PHPMailer/src/SMTP.php';
$mail = new PHPMailer(true); // Passing `true` enables exceptions
try {
//Server settings
$mail->SMTPDebug = 3; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'mygmailid#gmail.com'; // SMTP username
$mail->Password = '********'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587; // TCP port to connect to
//Recipients
$mail->setFrom('from#example.com', 'Mailer');
$mail->addAddress('xxx#gmail.com', 'Joe User'); // Add a recipient
$mail->addAddress('ellen#example.com'); // Name is optional
$mail->addReplyTo('info#example.com', 'Information');
$mail->addCC('cc#example.com');
$mail->addBCC('bcc#example.com');
//Attachments
//$mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
//$mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
//Content
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
$mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
}
?>

Gmail doesn't allow you to send form arbitrary from addresses, though you can create preset "aliases" in your account that it will allow you to use as alternative from addresses. If you try to use an arbitrary address, it will ignore it and send as your account address instead, as you're finding.
