<?php

    /* Attempt MySQL server connection. Assuming you are running MySQL

    server with default setting (user 'root' with no password) */

    try{

        $pdo = new PDO("mysql:host=localhost;dbname=demo2", "root", "");

        // Set the PDO error mode to exception

        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    } catch(PDOException $e){

        die("ERROR: Could not connect. " . $e->getMessage());

    }

     

    // Attempt search query execution

    try{

        if(isset($_REQUEST['term'])){

            // create prepared statement

            $sql = "SELECT * FROM countries WHERE name LIKE :term";

            $stmt = $pdo->prepare($sql);

            $term = $_REQUEST['term'] . '%';

            // bind parameters to statement

            $stmt->bindParam(':term', $term);

            // execute the prepared statement

            $stmt->execute();

            if($stmt->rowCount() > 0){

                while($row = $stmt->fetch()){

                    echo "<p>" . $row['name'] . "</p>";

                }

            } else{

                echo "<p>No matches found</p>";

            }

        }  

    } catch(PDOException $e){

        die("ERROR: Could not able to execute $sql. " . $e->getMessage());

    }

     

    // Close statement

    unset($stmt);

     

    // Close connection
