In this tutorial we are going to implement jQuery autocomplete search using PHP, MySQL and Ajax. This jQuery autocomplete gives suggestions when users starts to type on searchbox like in google search box. I had implemented two types of jQuery autocomplete 1. Simple jQuery autocomplete 2. Populate multiple textbox with single jQuery autocomplete request. For every letter user types something on textbox, ajax request will sent to the Apache server. There Apache server will commuincate with MySQL database and fetch some data’s based on the text users typed in the textbox. Finally Apache server sends the response to the ajax request sent by client, the response data will showed as suggestions to the users.
