How can hidden fields or unique identifiers be used to identify and delete specific database entries in PHP scripts?

To identify and delete specific database entries in PHP scripts, hidden fields or unique identifiers can be used. One way to do this is by including a hidden input field in a form that contains the unique identifier of the database entry to be deleted. This identifier can then be passed to the PHP script when the form is submitted, allowing the script to delete the corresponding database entry. 

<?php
if(isset($_POST['delete_entry'])) {
    $entry_id = $_POST['entry_id']; // Retrieve the unique identifier from the hidden field
    // Connect to database and execute DELETE query using $entry_id to delete specific entry
}
?>

<form method="post" action="delete_entry.php">
    <input type="hidden" name="entry_id" value="123"> <!-- Unique identifier of the entry to be deleted -->
    <input type="submit" name="delete_entry" value="Delete Entry">
</form>
