What are some potential ways to receive immediate notifications from a PHP script without using email?

One potential way to receive immediate notifications from a PHP script without using email is to utilize a messaging service such as Slack or Telegram. These services offer APIs that allow you to send notifications directly to a specific channel or user. By integrating your PHP script with one of these messaging services, you can receive real-time notifications whenever certain conditions are met.

// Example PHP code snippet to send a notification to a Slack channel using webhook

$webhookUrl = 'https://hooks.slack.com/services/your/webhook/url';
$message = 'Hello, this is a notification from your PHP script!';

$data = array('text' => $message);

$options = array(
    'http' => array(
        'header'  => "Content-type: application/json",
        'method'  => 'POST',
        'content' => json_encode($data)
    )
);

$context  = stream_context_create($options);
$result = file_get_contents($webhookUrl, false, $context);

if ($result === false) {
    echo 'Failed to send notification';
} else {
    echo 'Notification sent successfully';
}
