PHP PDO bind parameter example from http://www.phptherightway.com/#pdo_extension
<?php
$pdo = new PDO('sqlite:/path/db/users.db');
$stmt = $pdo->prepare('SELECT name FROM users WHERE id = :id');
$id = filter_input(INPUT_GET, 'id', FILTER_SANITIZE_NUMBER_INT); // <-- filter your data first (see [Data Filtering](#data_filtering)), especially important for INSERT, UPDATE, etc.
$stmt->bindParam(':id', $id, PDO::PARAM_INT); // <-- Automatically sanitized for SQL by PDO
$stmt->execute();
