How to make "PHPmailer" work in a function - php

Question

I don't know how to send a mail using PHPmailer in a function.
I want to do something similar to this - when I'll want to send a mail, I'll just call a function (like send::mail()). here is my code:
<?php
require '.\vendor\autoload.php';
//PHPMailer Object
use PHPMailer\PHPMailer\PHPMailer;
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->IsSendmail();
//From email address and name
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->setFrom('my.bot.mail#gmail.com', 'Bot name');
$mail->Password = "########"; // SMTP password
$mail->SMTPSecure = 'ssl'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 465;
//To address and name
$mail->addAddress("mymail#gmail.com"); //Recipient name is optional
//Address to which recipient will reply
//Send HTML or Plain Text email
$mail->isHTML(true);
$mail->Subject = "Subject Text";
$mail->Body = "<i>Mail body in HTML</i>";
$mail->AltBody = "This is the plain text version of the email content";
$mail->Mailer = "sendmail";
if(!$mail->send())
{
echo "Mailer Error: " . $mail->ErrorInfo;
}
?>
can someone help me put it into a function? when I tried, the "use" command didn't work.

First, you must determine the data.
$mailHost = '';
$mailSMTPAuth = '';
$mailUsername = '';
$mailPassword = '';
$mailSMTPSecure = '';
$mailPort = '';
$mailSenderAddress = '';
$mailSenderName = '';
Then you can generate a function that contains only the recipient, subject and message, and you can send the mail easily by pull the settings into this function:
function sendMail($sendMailAdress, $sendMailName, $sendMailSubject, $sendMailMessage) {
global $mailHost;
global $mailSMTPAuth;
global $mailUsername;
global $mailPassword;
global $mailSMTPSecure;
global $mailPort;
global $mailSenderAddress;
global $mailSenderName;
require_once('class/phpmailer/PHPMailerAutoload.php');
$mail = new PHPMailer;
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = $mailHost; // Specify main and backup SMTP servers
$mail->SMTPAuth = $mailSMTPAuth; // Enable SMTP authentication
$mail->Username = $mailUsername; // SMTP username or mail
$mail->Password = $mailPassword; // SMTP password
$mail->SMTPSecure = $mailSMTPSecure; // Enable TLS encryption, `ssl` also accepted
$mail->Port = $mailPort; // TCP port to connect to
$mail->CharSet = 'utf-8';
$mail->setFrom($mailSenderAddress, $mailSenderName);
$mail->addAddress($sendMailAdress, $sendMailName); // Add a recipient
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = $sendMailSubject;
$mail->Body = $sendMailMessage;
if(!$mail->send()) {
return false;
} else {
return true;
}
}
The function will work like this:
sendMail('hello#test.com', 'Test User', 'Subject of test mail', 'And your mail message);
