The SQL Server database created on Navicat premium can be connected with PHP (that is, PHP connects to Microsoft MSSQL). navicatpremium
can be used in Sybase’s db-lib or The ct-lib library also contains an ODBC library. Allows many applications to connect to Sybase or Microsoft SQL servers;
Use FreeTDS under windows
What is FreeTDS? FreeTDS is actually an open source (or can be said to be free) C program library, which can access and operate Microsoft's SQL database under the Linux system. FreeTDS is released as source code, and because of this, it can be compiled and installed on almost any system.
If your server is a Windows system, then you should use php_dblib.dll. (more information on Using FreeTDS for Unix.)
1: Follow the link below to download php_dblib.dll and save it to the /PHP/ext folder.
https://docs.moodle.org/30/en/Installing_MSSQL_for_PHP#Using_the_SQL_Server_2005_Driver_for_PHP_from_Microsoft_on_Windows
2. Add:
to the php configuration file /PHP/php.iniextension=php_dblib.dll Restart apache
3:Test:
1 <?<span>php </span>2 <span>$link</span> = mssql_connect('localhost', 'db_user', 'db_password'<span>); </span>3 <span>if</span>(!<span>$link</span><span>) { </span>4 <span>echo</span>'Could not connect'<span>; </span>5 <span>die</span>('Could not connect: ' .<span> mssql_error()); </span>6<span> } </span>7 <span>echo</span>'Successful connection'<span>; </span>8 mssql_close(<span>$link</span><span>); </span>9 ?>
ok, success!!!

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.
