What are the advantages and disadvantages of using header functions to pass variables in PHP forms?

Using header functions to pass variables in PHP forms can be advantageous because it allows for clean and simple redirection of data without cluttering the URL. However, it can also be disadvantageous because it may not be the most secure method of passing sensitive information, as the data is visible in the browser's network tab. Additionally, using header functions may not be the most efficient way to pass variables, as it requires an additional step of processing the data on the receiving end. 

<?php
// Set the variable to be passed
$variable = "Hello, world!";

// Redirect to another page with the variable passed using header function
header("Location: another_page.php?variable=" . urlencode($variable));
exit;
?>
