Based on the example that PHPMailer provides i have the script below,
date_default_timezone_set('Etc/UTC');
require './PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->isSMTP();
$mail->SMTPDebug = 2;
$mail->Debugoutput = 'html';
$mail->Host = 'smtp.gmail.com';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = "myemail@example.com";
$mail->Password = "********";
$mail->setFrom('myMail@example.com', 'First Last');
$mail->addReplyTo('myEmail@example.com', 'First Last');
$mail->addAddress('toEmail@example.com', 'first last');
$mail->Subject = 'PHPMailer GMail SMTP test';
$mail->Body = "example";
$mail->AltBody = 'This is a plain-text message body';
if (!$mail->send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}
Even if that is the exactly the same as the original example, i cannot get it to work.
The error that i get is
Warning: stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed in /opt/lampp/htdocs/webmail_client_practise/class.smtp.php on line 344 SMTP Error: Could not connect to SMTP host.
Notice: The OpenSSL extension in my php.ini file is already opened.

This is because you’re running PHP 5.6 and it’s verifying your certs, but your server is presenting invalid certs so it’s failing. Both PHPMailer and PHP are correct in what they are doing – the code is not at fault. You can either fix your mail server, or do what it suggests in the troubleshooting guide, which is:
$mail->SMTPOptions = array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
)
);
And as the guide says, you should not do this unless you have to – it’s compromising your security.
