What potential issues can arise when trying to send form data to multiple PHP files at once?

When trying to send form data to multiple PHP files at once, potential issues can arise with handling the data properly in each PHP file. To solve this, you can use PHP sessions to store the form data and access it across multiple PHP files. 

<?php
session_start();

// Store form data in session variables
$_SESSION['username'] = $_POST['username'];
$_SESSION['email'] = $_POST['email'];

// Redirect to another PHP file
header("Location: process_form_data.php");
exit;
?>
