What are the advantages and disadvantages of using separate PHP files for each form submission versus consolidating multiple forms in a single file for processing?

When deciding whether to use separate PHP files for each form submission or consolidate multiple forms in a single file for processing, it is important to consider factors such as organization, code reusability, and maintainability. Using separate PHP files for each form submission can help keep code organized and make it easier to debug and maintain. However, consolidating multiple forms in a single file can reduce code duplication and make it easier to manage shared resources. 

// Separate PHP files for each form submission
// Form 1 submission handling in form1.php
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST["submit_form1"])) {
    // Process form 1 data
}
?>

// Form 2 submission handling in form2.php
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST["submit_form2"])) {
    // Process form 2 data
}
?>

// Consolidating multiple forms in a single file for processing
// Form submission handling in process_forms.php
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_POST["submit_form1"])) {
        // Process form 1 data
    } elseif (isset($_POST["submit_form2"])) {
        // Process form 2 data
    }
}
?>
