For example, I this file and I don't want anyone to enter the address directly from the browser.

But if you connect from any Web site, you can access it.

This machine establishes the connection and cannot access the jump to another address

1. Write the following code on the head of the xx.php file

$fromurl = ""; Jump to this address.

if ($_server[' http_referer '] = = "")


Header ("Location:". $fromurl); Exit


This only needs to be simple to create a source on it, if we really want to do, you can do the following

2. Define an identity variable in the program

Define (' In_sys ', TRUE);

3. Get this variable in config.php

if (!defined (' In_sys ')) {

Exit (' no access ');


The next two methods are we encountered in many CMS oh.
