How to prevent the browser from accessing the website with php reporting 403

In web development, 403 errors generally refer to "access forbidden". In PHP, there are many ways to prevent the browser from accessing the website and report a 403 error. The following are several common methods:

1. Use .htaccess file

.htaccess file is a file placed in the website directory, which can be used to control the website access rights etc. Add the following code to the .htaccess file to prevent the browser from accessing the website and report a 403 error:

deny from all

This instruction means denying all access.

2. Using the PHP header() function

The header() function is an important function in PHP, which can be used to send HTTP header information. By outputting the 403 error header information through the header() function in the PHP code, the browser can be prohibited from accessing the website and reporting a 403 error:

header('HTTP/1.1 403 Forbidden');
exit();

This instruction means to send the 403 Forbidden error message using the HTTP 1.1 protocol, and Exit the current script.

3. Add instructions in the Apache configuration file

If you use Apache as a web server, you can add the following instructions in the Apache configuration file (httpd.conf) to disable the browser Access the website and report a 403 error:

<Directory "/var/www/html">
    Options None
    AllowOverride None
    Require all denied
</Directory>

This command means to set the access permission of the "/var/www/html" directory to "deny all".

It should be noted that although the above methods can prevent the browser from accessing the website and report a 403 error, the specific implementation method needs to be selected and optimized based on the actual situation.
