Installation

Use PHP Composer:

composer require shieldon/messenger

Or, download it and include the Messenger autoloader.

require './autoload.php';

Basic Usage

Public API methods:

• send
• debugMode
• printResult

Other than the Mailer classes, the only one public API is send(). The only thing you need to do is to assign the required data fields into constructor when initializing instance.

Telegram

Open your Telegram App, add BotFather to start a new conversation. Type command /newbot to obtain your API key.

Remember, make sure your channel type is public. If you want to send messages to your private channel, googling will find solutions.

$apiKey = 'your_api_key';
$channel = '@your_channel';

$telegram = new \Shieldon\Messenger\Telegram($apiKey, $channel);

if ($telegram->send('say something!')) {
    echo 'Message has been sent to your Telegram group.';
} else {
    echo 'Failed to send message.' . "\n";
    echo $telegram->printResult();
}

Line Notify

The access token can be obtained by clicking Generate token button at this signup page.

Once you have obtained your developer access token for the chat group you choose, invite Line Notify bot join your Line group, then the following code will work as expected.

$accessToken = 'your_access_token';

$line = new \Shieldon\Messenger\LineNotify($accessToken);

if ($line->send('say something!')) {
    echo 'Message has been sent to your Line group.';
} else {
    echo 'Failed to send message.' . "\n";
    echo $line->printResult();
}

RocketChat

$accessToken = 'your_auth_token';
$userId = 'your_user_id';
$serverUrl = 'https://your_rocket_chat.com:3000';
$channel = '#general';

$rocketChat = new \Shieldon\Messenger\RocketChat($accessToken, $userId, $serverUrl, $channel);

if ($rocketChat->send('say something!')) {
    echo 'Message has been sent to your RocketChat channel.';
} else {
    echo 'Failed to send message.' . "\n";
    echo $rocketChat->printResult();
}

Slack

Please clearfully read Slack's official API docs to find out things you need.

Guide:

• Create a App
• Assign channels:read and chat:write:bot permissions to your App.
• Assign your APP to your workspace.
• Obtain bot's access token.
• Add your App to the channel you would like to send messages.

$botToken = 'xoxb-551837935968-920623655894-TI1zWtaDLCkTzZaFFuyfzL56';
$channel = '#general';

$slack = new \Shieldon\Messenger\Slack($botToken, $channel);

if ($slack->send('say something!')) {
    echo 'Message has been sent to your Slack channel.';
} else {
    echo 'Failed to send message.' . "\n";
    echo $slack->printResult();
}

Slack Webhook

This would be the simplest way for messaging. Please clearfully read Slack's official API docs to find out things you need.

$webhook = 'https://hooks.slack.com/services/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';

$slack = new \Shieldon\Messenger\SlackWebhook($webhook);

if ($slack->send('say something!')) {
    echo 'Message has been sent to your Slack channel.';
} else {
    echo 'Failed to send message.' . "\n";
    echo $slack->printResult();
}

ok.

Mailer Usage

Public API methods:

• send
• addTo
• addCc
• addBcc
• addReplyTo
• addRecipient
• setRecipients
• setSubject
• setSender
• debugMode
• printResult

There is no need to metion content type when using Mailer, the content type is automatically detected.

Mail

Native PHP mail function. To use this class, be sure you have set the settings right in your php.ini.

$mail = new \Shieldon\Messenger\Mail();
$mail->addSender('example.sender@gmail.com');
$mail->addRecipient('example.recipient@gmail.com');
$mail->setSubject('Foo, bar.');

if ($mail->send('say something!')) {
    echo 'Email has been delivered via PHP\'s native mail function.';
} else {
    echo 'Failed to send email.' . "\n";
    echo $maingun->printResult();
}

SMTP

A very simple SMTP client.

$user = 'email@your_domain.com';
$pass = '12345678';
$host = '127.0.0.1';
$port = '25';

$mail = new \Shieldon\Messenger\Smtp($user, $pass, $host, $port);

$mail->addSender('email@your_domain.com');
$mail->addRecipient('do-not-reply@gmail.com');
$mail->setSubject('Foo, bar.');

if ($mail->send('say something!')) {
    echo 'Email has been delivered via SMTP.';
} else {
    echo 'Failed to send email.' . "\n";
    echo $maingun->printResult();
}

Note:

If you would like to use SMTPS or STARTTLS, the $host should have a prefix.

For example:

$host = 'ssl://smtp.gmail.com'; // SMTPS
$host = 'tls://smtp.gmail.com'; // STARTTLS

SendGrid

If you have SendGrid API key, you can also send messages via SendGrid easily.

$apiKey = 'your_api_key';

$sendgrid = new \Shieldon\Messenger\Sendgrid($apiKey);
$sendgrid->addSender('example.sender@gmail.com');
$sendgrid->addRecipient('example.recipient@gmail.com');
$sendgrid->setSubject('Foo, bar.');

if ($sendgrid->send('say something!')) {
    echo 'Email has been delivered via SendGrid API.';
} else {
    echo 'Failed to send email.' . "\n";
    echo $maingun->printResult();
}

MailGun

$apiKey = 'your_api_key';
$domain = 'your_domain_name';

$maingun = new \Shieldon\Messenger\Mailgun($apiKey, $domain);
$maingun->addSender('example.sender@gmail.com');
$maingun->addRecipient('example.recipient@gmail.com');
$maingun->setSubject('Foo, bar.');

if ($maingun->send('say something!')) {
    echo 'Email has been delivered via MailGun API.';
} else {
    echo 'Failed to send email.' . "\n";
    echo $maingun->printResult();
}

MailGun SMTP

Extended from Smtp, a ready-to-use MailGun SMTP client.

$user = 'your@gmail.com';
$pass = 'your_password';

$maingun = new \Shieldon\Messenger\Smtp\Mailgun($user, $pass);

$maingun->addSender('example.sender@gmail.com');
$maingun->addRecipient('example.recipient@gmail.com');
$maingun->setSubject('Foo, bar.');

if ($maingun->send('say something!')) {
    echo 'Email has been delivered via MainGun SMTP server.';
} else {
    echo 'Failed to send email.' . "\n";
    echo $maingun->printResult();
}

Gmail

Extended from Smtp, a ready-to-use Gmail SMTP client.

$user = 'your@gmail.com';
$pass = 'your_password';

$gmail = new \Shieldon\Messenger\Smtp\Gmail($user, $pass);

$gmail->addSender('your@gmail.com');
$gmail->addRecipient('test@gmail.com');
$gmail->setSubject('Foo, bar.');

if ($gmail->send('say something!')) {
    echo 'Email has been delivered via Gmail SMTP server.';
} else {
    echo 'Failed to send email.' . "\n";
    echo $gmail->printResult();
}

Note:

Google doesn't like people use their SMTP server to sending email by scripts, to make sure it can work without problems, you have to set the settings right:

• Check your Google Accounts -> Access for less secure apps -> Turn on
• Use your host where you use to send email with your Google account and confirm that you have trusted the device on.

Yahoo Mail

Extended from Smtp, a ready-to-use Yahoo SMTP client.

$user = 'your@yahoo.com';
$pass = 'your_password';

$yahooMail = new \Shieldon\Messenger\Smtp\Yahoo($user, $pass);

$yahooMail->addSender('your@yahoo.com');
$yahooMail->addRecipient('test@gmail.com');
$yahooMail->setSubject('Foo, bar.');

if ($yahooMail->send('say something!')) {
    echo 'Email has been delivered via Yahoo SMTP server.';
} else {
    echo 'Failed to send email.' . "\n";
    echo $yahooMail->printResult();
}

Note: You can use your account password but if you are facing the following error:

(#AUTH005) Too many bad auth attempts error when trying to send email.

That is because that Yahoo might not allow 3rd-party products access the SMTP server by default. To resolve this problem:

• Go to Account Security,
• Under Manage App password section, create a password for that App.
• Use your App password instead of your account password.

Outlook Mail (Office365)

Extended from Smtp, a ready-to-use Yahoo SMTP client.

$user = 'your@outlook.com';
$pass = 'your_password';

$outlook = new \Shieldon\Messenger\Smtp\Outlook($user, $pass);

$outlook->addSender('your@outlook.com');
$outlook->addRecipient('test@gmail.com');
$outlook->setSubject('Foo, bar.');

if ($outlook->send('say something!')) {
    echo 'Email has been delivered via Office365 SMTP server.';
} else {
    echo 'Failed to send email.' . "\n";
    echo $yahooMail->printResult();
}

Note:

When sending email via Office365 SMTP server at the first time, you will receive a notification email from Outlook.com Team to confirm your activity.

Once you have completed the validation, you will be able to send email via Office365 SMTP server.

Debug

debugMode()

If you would like to catch exceptions, you use turn debugMode on. This option will throw exceptions when error occurred.

For example:

$mail = new \Shieldon\Messenger\Smtp($user, $pass, $host, $port);

$mail->debugMode(true);

$mail->addSender('email@your_domain.com');
$mail->addRecipient('do-not-reply@gmail.com');
$mail->setSubject('Foo, bar.');

try {
    $mail->send('say something!');

} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}

printResult()

If you would like to print the executed results, you can use printResult().

For example:

$mail = new \Shieldon\Messenger\Smtp($user, $pass, $host, $port);
$mail->addSender('email@your_domain.com');
$mail->addRecipient('do-not-reply@gmail.com');
$mail->setSubject('Foo, bar.');
$mail->send('say something!');

echo $mail->printResult();

If the email is sent successfully, the result will look like the text below:

success: true
message: Email is sent.
--- result ---
