In PHP, what are the recommended approaches for handling form submissions from dynamically generated tables with varying numbers of fields?

When handling form submissions from dynamically generated tables with varying numbers of fields, one recommended approach is to use array notation for the field names in the HTML form. This allows you to easily loop through the submitted data in PHP and process it accordingly. Another approach is to include hidden input fields in each row of the table to store additional information or identifiers that can help you differentiate and process the data effectively. 

// HTML form with array notation for field names
<form method="post" action="process_form.php">
    <table>
        <tr>
            <th>Name</th>
            <th>Email</th>
        </tr>
        <?php for($i=0; $i<$num_rows; $i++): ?>
            <tr>
                <td><input type="text" name="name[]" /></td>
                <td><input type="email" name="email[]" /></td>
            </tr>
        <?php endfor; ?>
    </table>
    <input type="submit" value="Submit" />
</form>

// PHP code in process_form.php to handle form submission
<?php
if($_SERVER["REQUEST_METHOD"] == "POST"){
    $names = $_POST['name'];
    $emails = $_POST['email'];
    
    foreach($names as $key => $name){
        $email = $emails[$key];
        // Process the data as needed
    }
}
?>
