Hello fellows, Please how do one handle events in PHP controls? Or in other words do PHP have events handlers? I am directly referring to the ability to control events like mouse roll over, mouse on focus, mouse out of focus etc? I am presently working on a project that submits a form to a database.

PHP is a server side language, which means all execution is done on the server based (most of the time) upon individual requests from a browser.

in order for it to act upon something you do in the browser (other than responding to you calling a script with options POST/GET data), you need to also include a client-side language, such as Javascript.

Javascript can detect the user interaction, and then make calls to a script on a server usually via AJAX. PHP would process that script and output some type of information that the javascript can work with (such as JSON formatted data).

A big thing to remember is that unlike a standard standalone application, when you make a call to PHP, the script runs and then stops. Each interaction starts a fresh new call to scripts, so you need some method (usually $_SESSION) to keep track of a user's activity between each time a script is called.
