Install PHP using ISAPI.

ISAPI method is the most efficient PHP execution method under IIS in WIN system. Highly recommended.
After decompressing PHP, first find php.ini-dist
Remove -dist to display it in text mode.
Open PHP.INI and make slight modifications. Use the search method to find TMP. After finding ./TMP, change the path to C:/TMP
Then create a new TMP folder on the C drive
After everything is done, copy PHP. INI and php4ts.dll are placed in the WINNT/SYSTEM32 folder on the C drive.
OK The first step is done. Then set up IIS
Open IIS, right-click under the server name (the row with a small computer mark) and select Properties, Edit, ISAPI Filter
knowsky.com
Then select Add.
Filter name input: PHP
Executable file selection: php-4.4.0-Win32sapiphp4isapi.dll
Note that you must use php4isapi.dll instead of PHP.EXE. Because using PHP.EXE is the CGI method and occupies the process, php4isapi.dll is the ISAPI method.
Then add PHP permissions to a single website (note that PHP permissions must not be the default settings, unless you decide to give each website PHP permissions. Otherwise it is very dangerous)
Open IIS, right-click on the address you want to give permission to, and then select Properties, Home Directory, Configuration.
Then select Add.
Executable file input: .php
Lu Jin: php-4.4.0-Win32sapiphp4isapi.dll
OK The PHP permissions supporting ISAPI mode are ready. . . . . . .

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Managing concurrent session access in PHP can be done by the following methods: 1. Use the database to store session data, 2. Use Redis or Memcached, 3. Implement a session locking strategy. These methods help ensure data consistency and improve concurrency performance.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
