What is the best practice for generating input field names dynamically in PHP forms?

When generating input field names dynamically in PHP forms, it is best practice to use an array format for the input field names. This allows for easier handling of multiple input fields with similar names. By using array notation in the input field names, you can easily iterate through the values in PHP without having to manually handle each individual input field. 

<form method="post">
    <?php
    $num_fields = 5; // Number of input fields to generate
    for ($i = 1; $i <= $num_fields; $i++) {
        echo '<input type="text" name="field[' . $i . ']" /><br>';
    }
    ?>
    <input type="submit" value="Submit">
</form>

<?php
// Accessing the values submitted in the form
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $fields = $_POST['field'];
    foreach ($fields as $key => $value) {
        echo 'Field ' . $key . ': ' . $value . '<br>';
    }
}
?>
