How can PHP beginners improve their understanding of handling multiple checkbox selections in email transmissions?

When handling multiple checkbox selections in email transmissions using PHP, beginners can improve their understanding by looping through the selected checkboxes and appending their values to the email message. This way, all selected options will be included in the email content. 

// Assume checkboxes are named 'checkbox[]' in the HTML form
$selectedCheckboxes = $_POST['checkbox'];

$emailMessage = 'Selected options: ';
foreach ($selectedCheckboxes as $checkbox) {
    $emailMessage .= $checkbox . ', ';
}

// Send email with selected options
// Example using mail() function
$to = 'recipient@example.com';
$subject = 'Selected Options';
$headers = 'From: sender@example.com';
mail($to, $subject, $emailMessage, $headers);
