What are the potential pitfalls of using session variables for parameter passing in PHP?

Using session variables for parameter passing in PHP can lead to security vulnerabilities such as session hijacking or session fixation. To avoid these pitfalls, it is recommended to use other methods for parameter passing, such as passing parameters through URLs or using form submissions. 

// Example of passing parameters through URL
<a href="page.php?param1=value1&param2=value2">Link</a>

// Example of form submission for parameter passing
<form action="page.php" method="post">
    <input type="hidden" name="param1" value="value1">
    <input type="hidden" name="param2" value="value2">
    <button type="submit">Submit</button>
</form>
