What are some common methods to pass variables between PHP scripts using forms?

One common method to pass variables between PHP scripts using forms is to use the POST method. This involves creating a form with input fields where users can input data, and then submitting the form to a PHP script which can access the data using the $_POST superglobal array. Another method is to use the GET method, which appends the form data to the URL as query parameters. This allows the receiving PHP script to access the data using the $_GET superglobal array. 

<!-- Form to submit data using POST method -->
<form action="process.php" method="post">
    <input type="text" name="variable_name">
    <input type="submit" value="Submit">
</form>

// process.php
<?php
$variable = $_POST['variable_name'];
echo $variable;
?>
