Can't send email using PHPMailer using Gmail(Failed to connect server) - php

Question

i'm trying to send an email using PHPMailer. I've seen some topics about sending an email by Gmail servers using this package but i couldn't succeed.
$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 2; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail
$mail->Host = 'smtp.gmail.com';
$mail->Port = 587; // or 587
$mail->Username = "myEmailAddress#gmail.com";
$mail->Password = "MyGmailPassword";
$mail->setFrom('myEmailAddress#gmail.com', 'First Last');
$mail->addAddress('MyTargetEmail#example.com', 'John Doe');
$mail->Subject = 'PHPMailer GMail SMTP test';
$mail->Body = 'Text to be sent';
if(!$mail->send()){
echo 'message was not sent: ' . $mail->ErrorInfo;
}
else{
echo 'Successfully sent';
}
my response :
2018-11-29 14:56:37 SMTP ERROR: Failed to connect to server: (0)

Answer 1

You are sending the email to the wrong port/configuration. In your code you have it sent to Port 587 which handles stmp connections but you are sending it configured over ssl (which would need to be sent over port 465).
You ONLY need to change where it says ssl to "tls" and it will work.
$mail->SMTPDebug = 2; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'tls'; // secure transfer enabled REQUIRED for Gmail
$mail->Host = 'smtp.gmail.com';
$mail->Port = 587; // or 587

Try this with composer
require phpmailer/phpmailer
<?php
use PHPMailer\PHPMailer\PHPMailer;
require 'vendor/autoload.php';
$mail = new PHPMailer;
$mail->isSMTP();
$mail->SMTPDebug = 2;
$mail->Host = 'smtp.gmail.com';
$mail->Port = 587;
$mail->SMTPAuth = true;enter code here
$mail->Username = '#gmail.com';
$mail->Password = '';
$mail->setFrom('#gmail.com', '');
$mail->addReplyTo('#gmail.com', '');
$mail->addAddress('#gmail.com', ' Name');
$mail->Subject = 'This for Testing PHPMailer';
//$mail->msgHTML(file_get_contents('message.html'), __DIR__);
$mail->Body = 'This is a plain text message body';
//$mail->addAttachment('test.txt');
if (!$mail->send()) {
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'The email message was sent.';
}
?>
