How to implement hidden source jump in php

With the popularity of the Internet, websites are increasingly required to protect user information security. Among them, the "hidden source jump" technology plays an important role in achieving this goal.

PHP language is mainly used in website development, and the "hidden source jump" technology implementation method is also mainly based on PHP. Next, let us introduce the implementation method and function of this technology.

1. Implementation method of hiding source jump

When a user visits a website, the source of the request is called the "reference" (i.e. Referer). The "hidden redirect" technology is to hide the source of the visit, especially when jumping users from one website to another.

The implementation method is as follows:

1. Add the access source to the URL required for the jump, for example:

$url = 'https://targetwebsite.com';
header("Location:$url");

2. Add the following to the PHP file of the target page Code:

if($_SERVER['HTTP_REFERER'] != 'https://originalwebsite.com'){
   header('Location: https://originalwebsite.com');
   exit;
}

Among them, "https://originalwebsite.com" is the page currently visited by the user, and "https://targetwebsite.com" is the target page to be jumped to. In the code, HTTP_REFERER represents the HTTP protocol header of the access source. If the source is not "https://originalwebsite.com", it will jump back to the "https://originalwebsite.com" page.

2. The role of hidden redirection

Implementing the "hidden redirection" technology can enhance the protection of the website and improve the security of user information.

The following are several practical application scenarios:

1. Prevent information leakage

Suppose you have a product purchase page. After the user fills in the relevant information, click "Submit" Click the button to purchase. Then when jumping to the "payment page", the user's relevant information needs to be protected to avoid being obtained by hackers. At this time, the "hidden source jump" technology perfectly solves this problem.

2. Avoid origin deception

If your website contains certain functions to control the security of user accounts, such as password changes, etc., then it is obviously necessary to authenticate the user before use. . But if the hacker uses a fake origin to jump to the password change page, then he can change the user's password at will. At this time, the "hidden source jump" technology solves this problem very well.

3. Prevent malicious traffic brushing

If a website is advertising and the source link of the advertisement is clicked maliciously, it may cause malicious traffic brushing. In order to prevent this from happening, the use of "hidden redirection" technology can effectively prevent malicious traffic brushing.

The above is the implementation method and function of "PHP hidden source jump". This technology reflects the power and flexibility of the PHP language, and can also help websites improve their information security protection capabilities and provide users with better services.
