To create an Ajax search functionality using PHP, you can follow the steps below:

  1. Create a PHP script that retrieves the search results based on the user’s input. For example, you can use a MySQL database to store the data and use the SELECT statement to retrieve the matching results.
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

// Retrieve search results
$search = $_POST['search'];
$sql = "SELECT * FROM mytable WHERE name LIKE '%".$search."%'";
$result = $conn->query($sql);

// Output results
while($row = $result->fetch_assoc()) {
    echo "<li>".$row["name"]."</li>";

// Close the database connection
  1. Create a form in HTML that allows users to enter their search query.
htmlCopy code<form>
    <input type="text" id="search" placeholder="Search...">
    <ul id="results"></ul>
  1. Create a JavaScript file that sends an Ajax request to the PHP script and displays the results on the page.
javascriptCopy code$(document).ready(function(){
        var query = $(this).val();

        if(query != ''){
                url: 'search.php',
                method: 'POST',
                data: {search:query},
                success: function(data){

This script uses jQuery to listen for keyup events on the search input field. When the user enters a query, it sends an Ajax request to the PHP script, passing the search query as a POST parameter. The PHP script retrieves the matching results from the database and outputs them as a list of HTML elements. Finally, the JavaScript file displays the search results on the page by updating the contents of the “results” unordered list.
