What is the main issue the user is facing when trying to pass individual form data in a loop in PHP?

The main issue the user is facing is that when passing individual form data in a loop in PHP, the form field names need to be unique for each input to properly capture the data. One solution is to append an index or identifier to the field names in the form and then process the data accordingly in the PHP script. 

<form method="post">
    <?php
    $data = array('name', 'email', 'phone');
    foreach ($data as $key => $value) {
        echo '<input type="text" name="' . $value . '_' . $key . '" placeholder="' . ucfirst($value) . '"><br>';
    }
    ?>
    <input type="submit" name="submit" value="Submit">
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    foreach ($data as $key => $value) {
        $field_name = $value . '_' . $key;
        $form_data[$value] = $_POST[$field_name];
    }
    
    // Process the form data as needed
    print_r($form_data);
}
?>
