What is the purpose of sending a form multiple times and how can this be achieved in PHP?

Sending a form multiple times can be useful in cases where a user needs to submit multiple entries or update multiple records. This can be achieved by using a loop in PHP to process the form data multiple times, each time with different values. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $numEntries = $_POST['num_entries'];

    for ($i = 1; $i <= $numEntries; $i++) {
        $data = $_POST['data_' . $i];
        // Process the form data for each entry
    }
}
?>

<form method="post">
    <label for="num_entries">Number of Entries:</label>
    <input type="number" name="num_entries" id="num_entries">

    <?php for ($i = 1; $i <= $numEntries; $i++) { ?>
        <label for="data_<?php echo $i; ?>">Data <?php echo $i; ?>:</label>
        <input type="text" name="data_<?php echo $i; ?>" id="data_<?php echo $i; ?>">
    <?php } ?>

    <button type="submit">Submit</button>
</form>
