What are the advantages and disadvantages of using absolute paths versus relative paths in PHP form actions?

When specifying form actions in PHP, using absolute paths can provide a more reliable way to ensure the form submission goes to the correct location regardless of the current page's location. However, using relative paths can make the code more portable and easier to maintain as the website structure changes. It is important to weigh the pros and cons of each approach based on the specific needs of the project.

// Absolute path example
<form action="http://www.example.com/process_form.php" method="post">
    <!-- form fields here -->
</form>

// Relative path example
<form action="../process_form.php" method="post">
    <!-- form fields here -->
</form>
