phpmailer issue. Unable to get rid of the smtp connect() error - php

Question

I'm trying to send a mail using phpmailer but getting this error "SMTP connect() failed". I've already allowed less secure apps on gmail. Is all the smtp setting correct? Please guide me where I'm wrong.
<?php
require_once 'PHPMailer-master/PHPMailerAutoload.php';
require 'PHPMailer-master/class.phpmailer.php';
require 'PHPMailer-master/class.smtp.php';
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPAuth = true;
$mail->host = 'smtp.gmail.com';
$mail->username = 'mymail#gmail.com';
$mail->password = 'mypassword';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;
$mail->SMTPDebug = true;
$mail->isHTML();
$mail->Subject = 'form data';
$mail->Body = 'this is the body of message';
$mail->FromName = 'The Form';
$mail->AddAddress('junaidshekh21#gmail.com','Junaid Shaikh');
if($mail->send())
{
echo "sent successfully";
die();
}
else
{
echo "could not send";
}
?>

Answer 1

Use ErrorInfo in phpmail to see what's wrong
add this before sending the email
$mail->SMTPDebug = 2; //enables SMTP debug information (for testing)
and change from
echo "could not send";
to
echo "Mailer Error: " . $mail->ErrorInfo;
Notes:
Read the phpmail troubleshooting, specifically the part that talks
about "SMTP Error: Could not connect to SMTP host."
Use the official gmail example from the phpmailer github repo.
You may have to allow less secure apps to access your gmail
account
Your ip may be blocked by google.
UPDATE:
From the official phpmailer gmail example:
$mail->Host = gethostbyname('smtp.gmail.com');
// if your network does not support SMTP over IPv6

Answer 2

Your PHPmailer settings are ok i think it was less secure app access problem.
you must make your gmail to less secure to get access.
got to this url https://www.google.com/settings/security/lesssecureapps
to access your gmail as SMTP.
