What are best practices for passing data between PHP files for email sending purposes?

When passing data between PHP files for email sending purposes, it is recommended to use sessions or POST requests to securely transfer sensitive information like email addresses or message content. Sessions can store data across multiple pages, while POST requests can send data from one page to another without displaying it in the URL. 

// Sending email data from one PHP file to another using sessions
session_start();

// Set email data in session variables
$_SESSION['email_address'] = 'recipient@example.com';
$_SESSION['email_subject'] = 'Subject of the email';
$_SESSION['email_message'] = 'This is the email message content';

// Redirect to the PHP file responsible for sending the email
header('Location: send_email.php');
exit;
