How can PHP developers prevent updating all database records when clicking a button in a loop?

When clicking a button in a loop, PHP developers can prevent updating all database records by ensuring that the button click triggers an update only for the specific record associated with that button. This can be achieved by passing a unique identifier (such as the record ID) along with the button click event, and using this identifier to target the specific record for update in the database. 

// Sample code snippet to demonstrate preventing updating all database records when clicking a button in a loop

// Assuming a form with buttons in a loop, each button representing a record
foreach ($records as $record) {
    echo "<form method='post'>";
    echo "<input type='hidden' name='record_id' value='" . $record['id'] . "'>";
    echo "<input type='submit' name='update_record' value='Update Record'>";
    echo "</form>";
}

// Handling the button click event to update only the specific record
if (isset($_POST['update_record'])) {
    $record_id = $_POST['record_id'];
    
    // Perform database update query for the record with $record_id
    // Example: UPDATE records SET column = value WHERE id = $record_id
}
