Do not recreate the wheel to send mails ! Use Swift Mailer library.

Swift Mailer integrates into any web app written in PHP 5, offering a flexible and elegant object-oriented approach to sending emails with a multitude of features easy to implement.

Learn in this article how to install and use this library.

Installation

The preferred way to install Swiftmailer is via Composer:

$ composer require swiftmailer/swiftmailer

or add to your composer.json file in the require block

"swiftmailer/swiftmailer": "v5.4.0",

or if you use Symfony 2

"symfony/swiftmailer-bundle": "~2.3",

If you don't use Composer download the zip file in https://github.com/swiftmailer/swiftmailer

Sending mails

The algorithm to send a message is very easy to understan. You create a Transport, use it to create the Mailer, then you use the Mailer to send the message.

The mails can contain plain/text or html/text according to the configuration.

If the SwiftMailer class doesn't exist, don't forget to require it with php if the composer autoloader didn't work

require_once 'lib/swift_required.php';

Sending mail from outlook (hotmail)

Sending mails from outlook is a little bit different, as you can see outlook uses TLS encryption instead SSL and uses the port 587.

$transport = \Swift_SmtpTransport::newInstance()
            ->setUsername('[email protected]')->setPassword('mypassword')
            ->setHost('smtp-mail.outlook.com')
            ->setPort(587)->setEncryption('tls');

$mailer = \Swift_Mailer::newInstance($transport);
        
$message = \Swift_Message::newInstance()
       ->setSubject($param['title'])
       ->setFrom(array('[email protected]' => 'I am someone'))
       ->setTo(array('[email protected]' => "[email protected]"))
       ->addPart("<h1>Welcome</h1>",'text/html')
;
        
$result = $mailer->send($message);

Sending mail from google (gmail)

Google uses SSL encryption and the port 465. Is important to know that sometimes , the gmail accounts doesn't allow to send mails with swiftmailer and you need to uncheck the property "Allows the use on unsafe devices" in your gmail account.

$transport = \Swift_SmtpTransport::newInstance('smtp.gmail.com', 465,'ssl')->setUsername('[email protected]')->setPassword('mypassword');

$mailer = \Swift_Mailer::newInstance($transport);
$message = \Swift_Message::newInstance('Our Code World Newsletter')
   ->setFrom(array('[email protected]' => 'Our Code World'))
   ->setTo(array("[email protected]" => "[email protected]"))
   ->setBody("<h1>Welcome</h1>", 'text/html');
$result = $mailer->send($message);

Sending mail from zoho(zoho mail)

Zoho uses SSL encryption and the port 465.

$transport = \Swift_SmtpTransport::newInstance('smtp.zoho.com', 465,'ssl')->setUsername('[email protected]')->setPassword('mypassword');

$mailer = \Swift_Mailer::newInstance($transport);
$message = \Swift_Message::newInstance('Test')
     ->setFrom(array('[email protected]' => 'Our Code World'))
     ->setTo(array("[email protected]" => "[email protected]"))
     ->setBody("<h1>Welcome</h1>", 'text/html');
$mailer->send($message);

A frequent question for the swiftmailer user is what is the smtp for hotmail, zoho or gmail (or what is the smtp for my email account) ?
