The wonderful use of php include to achieve path encryption_PHP tutorial

1. Transfer program include.inc

Copy code The code is as follows:

include_once 'include/Base.php';
$path = '';
$url = isBase::decrypt(urlDecode($_SERVER['QUERY_STRING']));
parse_str($url) ; //Get the variable passed by url address GET
if(!empty($_POST['path'])){ //Get the variable passed by POST
$path = $_POST['path' ];
$path = isBase::decrypt(urlDecode($path));
}
//Resolve the real path
if(empty($path)){
//header ("Location: login.php");
exit;
}
if(!preg_match("/(^http:/)|([?|&|=])/",$path )){
//Jump to the path of the actual executed file
chdir(dirname($path));
include_once basename($path);
exit;
}
?>

index.php is in the same directory as include.inc

Copy the code The code is as follows:

include include.inc;
?>

2. Modify the link in the program ()

Copy code The code is as follows:

"index.php?".encrypt("path=/test/test.php&test=123&test2=4321")

3. Modify the POST form in the program
Form is submitted to index.php
Add a hidden form in the middle

4. Modify the path of the front-end Html page
baseref=/test

5. Encryption and decryption Function, friends, write it yourself.

Summary:
Using this method is more cumbersome and can only hide the path of the background script. The path of the front-end script can still be seen in the source file (baseref) and can be seen on the address bar The addresses are all index.php?xxxxxxxx
