The failure of the Hosts file has undoubtedly brought a lot of trouble to our work. Regarding the failure of the Hosts file, the editor will make a simple analysis. [size=12.631579399108887px] 1. If you have ever manually modified the hosts file, I wonder if you have noticed such a phenomenon, that is, a svchost.exe process attempt will appear in the task manager process of the Win8 system Access the hosts file, but the access result is Access Denied.
[size=12.631579399108887px] 2. According to the process PID provided by the message recorder, it can be traced that one of the hosted services is DNS Client, and it can be concluded that the DNS Client service has gone wrong. Then this must be an account problem. You can open the DNS Client property page, switch to the login page and check whether the above account is the default local system account, but Network Service.
[size=12.631579399108887px] 3. From the above analysis, it can be clearly judged that it is a problem with the win8 system account permissions. Therefore, the solution is to edit the access permissions of the Etc folder, add the Network Service security principal, and grant some permissions to allow reading, and then restart the DNS Client service.

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
