How does php disable access methods?

php Ways to disable direct access to.php files from browser input addresses:

The specific implementation method is as follows:

Generally speaking, for some important files we do not want users to directly enter the address to access, we need to make some settings. Here is a summary of some php methods that prohibit accessing.PHP files directly from the browser input address, which is very practical.

For example, www.jb51.net/xx.php is a file I don't want anyone to access directly from the browser.

However, if you cannot access https://www.jb51.net/xx.php from any website, you cannot jump to another address if you establish a connection with this machine.

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

The code is as follows:

$fromurl="https://www.jb51.net/"; //jump to this address. if( $_SERVER['HTTP_REFERER'] == "" ){header("Location:".$ fromurl); exit;}

This way, we only need to simply falsify the source. For this, we can also do the following:

2. Define an identification variable in your program

The code is as follows:

define('IN_SYS', TRUE);

3. Get this variable in config.php

The code is as follows:

if(! defined ('IN_SYS')) { exit ('Forbidden access'); }

The latter two methods are ones we encounter in many cms.
