php prohibits accessing .php files by directly entering the address from the browser,

The example in this article describes how PHP prohibits accessing .php files by directly entering the address from the browser. Share it with everyone for your reference. The specific implementation method is as follows:

Generally speaking, we do not want users to directly enter the address to access some important files, so we need to make some settings for this. The following summarizes some PHP methods to prohibit accessing .PHP files directly from entering the address in the browser, which are very practical.

For example, I don’t want others to access the file http://www.bkjia.com/xx.php by entering the address directly from the browser.

But if you cannot access http://www.bkjia.com/xx.php from any website, you will not be able to access it even if you establish a connection locally and jump to another address.

1. Just write the following code in the header of the xx.php file

Copy code The code is as follows:

$fromurl="http://www.bkjia.com/"; //Jump to this address.
if( $_SERVER['HTTP_REFERER'] == "" )
{
header("Location:".$fromurl); exit;
}

In this way, we only need to simply forge the source. For this, we can also do the following:
2. Define an identification variable in the program

Copy code The code is as follows:

define('IN_SYS', TRUE);

3. Get this variable in config.php

Copy code The code is as follows:

if(!defined('IN_SYS')) {
exit('Access prohibited');
}

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