3 methods for php page access control

We often see this phenomenon, see the picture below

apache page access control

Why should we carry out such control? People look at different things and protect information. Although this kind of protection is relatively low-level, it is still somewhat useful.

First, use the htpasswd command to generate the permission control file

[zhangy@BlackGhost test]$ htpasswd -c ./access tank  //生成一个密码文件 ,-c是新建一个文件  htpasswd -h可查看
New password:            //提示输入密码
Re-type new password:        //重复密码
Adding password for user tank  
[zhangy@BlackGhost test]$ cat access    //查看一下密码文件
tank:Uj5B3qIF/BNdI      //用户名是明文的,密码是加密的。
Copy after login
[zhangy@BlackGhost test]$ htpasswd -c ./access tank  //生成一个密码文件 ,-c是新建一个文件  htpasswd -h可查看
New password:            //提示输入密码
Re-type new password:        //重复密码
Adding password for user tank
[zhangy@BlackGhost test]$ cat access    //查看一下密码文件
tank:Uj5B3qIF/BNdI      //用户名是明文的,密码是加密的。
Copy after login

The password file is now generated.

2. Page access control method

1, which can be configured by modifying httpd.conf or httpd-vhosts.conf

listen 10004  
NameVirtualHost *:10004  
<VirtualHost *:10004>  
 DocumentRoot "/home/zhangy/www/test"
 ServerName *:10004  
 BandwidthModule On  
 ForceBandWidthModule On  
 Bandwidth all 1024000  
 MinBandwidth all 50000  
 LargeFileLimit * 500 50000  
 MaxConnection all 2  
 ErrorLog "/home/zhangy/apache/blog.51yip.com.com-error.log"
 CustomLog "/home/zhangy/apache/blog.51yip.com-access.log" common  
//看一下,下面的配置
 <Directory /home/zhangy/www/test>  
 AuthType Basic  
 AuthName "access test"
 AuthUserFile /home/zhangy/www/test/access  
 Require valid-user  
 </Directory>  
</VirtualHost>
Copy after login
listen 10004
NameVirtualHost *:10004
<VirtualHost *:10004>
 DocumentRoot "/home/zhangy/www/test"
 ServerName *:10004
 BandwidthModule On
 ForceBandWidthModule On
 Bandwidth all 1024000
 MinBandwidth all 50000
 LargeFileLimit * 500 50000
 MaxConnection all 2

 ErrorLog "/home/zhangy/apache/blog.51yip.com.com-error.log"
 CustomLog "/home/zhangy/apache/blog.51yip.com-access.log" common
//看一下,下面的配置
 <Directory /home/zhangy/www/test>
 AuthType Basic
 AuthName "access test"
 AuthUserFile /home/zhangy/www/test/access
 Require valid-user
 </Directory>

</VirtualHost>
Copy after login

2, we can use the .htaccess file for control

Create a .htaccess file under the root directory of test

[zhangy@BlackGhost test]$ vi .htaccess   //打开个文件 ,添加权限内容
[zhangy@BlackGhost test]$ cat .htaccess  //下面就是.htaccess的内容
 AuthType Basic  
 AuthName "access test"
 AuthUserFile /home/zhangy/www/test/access  
Require valid-user
Copy after login
[zhangy@BlackGhost test]$ vi .htaccess   //打开个文件 ,添加权限内容
[zhangy@BlackGhost test]$ cat .htaccess  //下面就是.htaccess的内容
 AuthType Basic
 AuthName "access test"
 AuthUserFile /home/zhangy/www/test/access
 Require valid-user
Copy after login

If you want to Many people set different user names and passwords. It is more convenient to use AuthGroupFile to set options

3. Access control can also be performed without a password file

  1. define(&#39;ADMIN_USERNAME&#39;,&#39;tank&#39;);     // Admin Username
    define(&#39;ADMIN_PASSWORD&#39;,&#39;tank&#39;);      // Admin Password
    //log check
    if (!isset($_SERVER[&#39;PHP_AUTH_USER&#39;]) || !isset($_SERVER[&#39;PHP_AUTH_PW&#39;]) ||  
     $_SERVER[&#39;PHP_AUTH_USER&#39;] != ADMIN_USERNAME ||$_SERVER[&#39;PHP_AUTH_PW&#39;] != ADMIN_PASSWORD) {  
     Header("WWW-Authenticate: Basic realm=/"access test/"");  
     Header("HTTP/1.0 401 Unauthorized");  
     echo <<<EOB  
     <html><body>  
     <h1>Rejected!</h1>  
     <big>Wrong Username or Password!</big>  
     </body></html>  
    EOB;  
     exit;  
    }
    Copy after login
define(&#39;ADMIN_USERNAME&#39;,&#39;tank&#39;);     // Admin Username
define(&#39;ADMIN_PASSWORD&#39;,&#39;tank&#39;);      // Admin Password

//log check
if (!isset($_SERVER[&#39;PHP_AUTH_USER&#39;]) || !isset($_SERVER[&#39;PHP_AUTH_PW&#39;]) ||
 $_SERVER[&#39;PHP_AUTH_USER&#39;] != ADMIN_USERNAME ||$_SERVER[&#39;PHP_AUTH_PW&#39;] != ADMIN_PASSWORD) {
 Header("WWW-Authenticate: Basic realm=/"access test/"");
 Header("HTTP/1.0 401 Unauthorized");

 echo <<<EOB
 <html><body>
 <h1>Rejected!</h1>
 <big>Wrong Username or Password!</big>
 </body></html>
EOB;
 exit;
}
Copy after login

The method used above is PHP, I think there are other languages ​​too. You can write the above code into a file for sharing and inclusion, or you can encapsulate it into the base, so that no matter what page is accessed, access control can be carried out.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
