$(document).ready(function(){
    $('.live_searchBox input[type="text"]').on("keyup input", function(){

        if(form_liveval.length){
            $.get("backend-search.php", {query_string: form_liveval}).done(function(data){
                //Devloped By Pakainfo.com :  Display the returned data in browser
                live_results_searchDropdown.html(data);
            });

Phase 3: Processing Search Query in Backend

<?php
/* Attempt MySQL server connection. Assuming you are running MySQL
server with default setting (user 'root' with no password) */
$db_link = mysqli_connect("localhost", "root", "", "demo");
 
// Check connection
if($db_link === false){
    die("ERROR: db Could not connect. " . mysqli_connect_error());
}
 
if(isset($_REQUEST['query_string'])){
    //Devloped By Pakainfo.com Prepare a select statement
    $sql = "SELECT * FROM students WHERE name LIKE ?";
    
    if($stmt = mysqli_prepare($db_link, $sql)){
        //Devloped By Pakainfo.com Bind variables to the prepared statement as parameters
        mysqli_stmt_bind_param($stmt, "s", $param_query_string);
        
        //Devloped By Pakainfo.com Set parameters
        $param_query_string = $_REQUEST['query_string'] . '%';
        
        //Devloped By Pakainfo.com Attempt to execute the prepared statement
        if(mysqli_stmt_execute($stmt)){
            $live_results_search = mysqli_stmt_get_live_results_search($stmt);
            
            //Devloped By Pakainfo.com Check number of rows in the live_results_search set
            if(mysqli_num_rows($live_results_search) > 0){
                // Fetch live_results_search rows as an associative array
                while($row = mysqli_fetch_array($live_results_search, MYSQLI_ASSOC)){
                    echo "<p>" . $row["name"] . "</p>";
                }
            } else{
                echo "<p>No matches found</p>";
            }
        } else{
            echo "ERROR: sorry Could not able to execute $sql. " . mysqli_error($db_link);
        }
    }
     
    // Devloped By Pakainfo.com Close statement
    mysqli_stmt_close($stmt);
}
 
//Pakainfo.com close connection
mysqli_close($db_link);
