How can a "Fatal error" be handled in PHP to trigger a specific action, such as sending an email with error details?

When a "Fatal error" occurs in PHP, it typically stops the script execution immediately, making it difficult to handle and log the error details. To handle a "Fatal error" and trigger a specific action, such as sending an email with error details, you can use a combination of the register_shutdown_function() function and the error_get_last() function. By registering a shutdown function that checks for the last error and sends an email if it is a fatal error, you can ensure that critical errors are logged and action is taken. 

register_shutdown_function(function() {
    $error = error_get_last();
    
    if ($error !== null && $error['type'] === E_ERROR) {
        $error_message = "Fatal error: " . $error['message'] . " in " . $error['file'] . " on line " . $error['line'];
        
        // Send an email with the error details
        $to = "your@email.com";
        $subject = "Fatal Error";
        $message = $error_message;
        $headers = "From: webmaster@example.com";
        
        mail($to, $subject, $message, $headers);
    }
});
