Detailed explanation of php data serialization testing
This article mainly introduces relevant information about the detailed explanation of php data serialization test examples. It mainly introduces the comparison of msgpack, json, and serialize. Friends in need can refer to
php data serialization test examples. Detailed explanation
Test code
$msg = ['test'=>23]; $start = microtime(true); for($i=0;$i<100000;$i++){ $packMsg = msgpack_pack($msg); } echo 'pack len:'.strlen($packMsg)."\r\n"; $end = microtime(true); echo 'run time:'.($end-$start).'s'."\r\n"; echo 'memory usage:'.(memory_get_usage()/1024)."KB\r\n"; /* $start = microtime(true); for($i=0;$i<100000;$i++){ $jsonMsg = json_encode($msg); } echo 'json len:'.strlen($jsonMsg)."\r\n"; $end = microtime(true); echo 'run time:'.($end-$start).'s'."\r\n"; echo 'memory usage:'.(memory_get_usage()/1024)."KB\r\n"; $start = microtime(true); for($i=0;$i<100000;$i++){ $packMsg = serialize($msg); } echo 'php len:'.strlen($packMsg)."\r\n"; $end = microtime(true); echo 'run time:'.($end-$start)."s\r\n"; echo 'memory usage:'.(memory_get_usage()/1024)."KB\r\n";*/
Execution results

Analysis and comments
The basic results of online searches are all (presumably versions before php7)
运行速度 serialize<json<msgpack 长度 serialize>json>msgpack 内存消耗 serialize<json<msgpack //不过近乎一致
Run in php7, the results are as follows
运行速度 serialize<msgpack<json //这里出现了变化 长度 serialize>json>msgpack 内存消耗 serialize<json<msgpack //不过近乎一致

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.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
