Unable to send mails from gmail smtp

Question

I am using Gmail SMTP for sending emails in php. The code is working fine in one of my client website. When I am using the same code for another client website, I am getting an error like "Could not authenticate, SMTP connect() failed.

https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting"

. I don't have knowledge in server settings. Both websites are on different servers. Please check the below code.

<?php
require 'PHPMailer/PHPMailerAutoload.php';

$mail = new PHPMailer;

$mail->Host = 'smtp.gmail.com';

//$mail->isSMTP();
$mail->SMTPDebug = 2;

$mail->SMTPAuth = true;                               
$mail->Username = 'example@gmail.com';                
$mail->Password = 'password';                          
$mail->SMTPSecure = 'ssl';                           
$mail->Port = 465;  // for tls 587

$mail->Subject = 'Test Email';

$mail->isHTML(true);

$mail->Body = 'Message from test website';

$mail->setFrom('mahmood.bts@gmail.com');


$mail->addAddress('test@companyname.com');
$mail->addCC('info@companyname.com');

if($mail->send())
    echo "mail is sent";

    else 
      echo $mail->ErrorInfo;

 ?>

I used php mail function instead of SMTP, Then also I am unable to send emails. Please help me.

what is error ? Please check how to ask question https://stackoverflow.com/help/how-to-ask — Jagdish Chaudhary, Jan 21 '19 at 10:13
You need to allow untrusted apps from `mahmood.bts@gmail.com` account. — darklightcode, Jan 21 '19 at 10:13
But is working another website without this setting. Anyway i will change this and test again. — Mahmood Moahammed, Jan 21 '19 at 10:16
Is my code is correct? or if there is any another way to send mails, Please explain me. — Mahmood Moahammed, Jan 21 '19 at 10:20

Do not send emails this way with a different `From` address, than the one you are authenticating against - that is asking for trouble with spam filters. — misorude, Jan 21 '19 at 12:15

You should allow sending emails from an untrusted app.

Google may block sign-in attempts from some apps or devices that do not use modern security standards. Since these apps and devices are easier to break into, blocking them helps keep your account safe.

To disable this security feature:

Sign in to Gmail
Click here to access Less Secure App Access in My Account.
Next to “Allow less secure apps: OFF”, select the toggle switch to turn ON.
