In this new tutorial from Script-Tutorials.com they show you how to combine PHP, jQuery, MySQL and XML to create an auto-complete box with drop-down suggestions.

Today I have new article for PHP. I will tell you about implementation autocomplete for your sites. Data can be located in different sources - directly in the JS code, in the database, and even in the XML file.

All of the code and markup you'll need is included - the HTML for the page containing the field, CSS to style it, the Javascript (jQuery) to make the field work and the SQL/PHP/XML for the backend. You can check out a live demo of the script in action here or download the source in a single package and get started.
