STEP 1: Using Header()
When a script communicates with a client browser, the server will send headers to the client to let the browser know how to handle the server document.
To send headers to the client manually we use the header() function. Before you use the header() function, you must make sure that no output has been sent to the client browser first. There is a way around this using output buffering that I will go over later.
When relocating a user we send the "Location" header to the client. The syntax looks like this:
header("Location: yourPage.php");
or like this:
header("Location: http://www.joelucky39.com");

STEP 2: Output Buffering
If you must put your redirect at the bottom of a script following some client output then we must use output buffering. For instance if your script requires an include file that occurs before you can place your header() function, the server will send output to the client prior to your redirect.
Output buffering insures that the script is totally run and completed prior to any headers being sent to the client browser.
You begin output buffering using the ob_start(); function and close it with the ob_end_flush(); function.
So the syntax would look like so:
<?
ob_start();
Your script here
header("Location: http://www.joelucky39.com");
ob_end_flush();
?>
