What are the potential pitfalls of using the same form name and field names in PHP for multiple records?

Using the same form name and field names for multiple records can lead to data overwriting issues when processing the form in PHP. To avoid this problem, you can append unique identifiers to the field names for each record, such as record IDs. This way, each record's data will be distinct and can be processed correctly. 

<form method="post">
    <input type="text" name="record[1][field1]">
    <input type="text" name="record[1][field2]">
    <input type="text" name="record[2][field1]">
    <input type="text" name="record[2][field2]">
    <!-- Add more fields for additional records -->
    <button type="submit" name="submit">Submit</button>
</form>

<?php
if(isset($_POST['submit'])) {
    foreach($_POST['record'] as $record) {
        $field1 = $record['field1'];
        $field2 = $record['field2'];
        // Process the data for each record
    }
}
?>
