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 it. I hope it can help everyone.

Detailed explanation of php data serialization test example

Test code


$msg = ['test'=>23];
$start = microtime(true); 
for($i=0;$i<100000;$i++){
  $packMsg = msgpack_pack($msg);
}
echo &#39;pack len:&#39;.strlen($packMsg)."\r\n";
$end = microtime(true);
echo &#39;run time:&#39;.($end-$start).&#39;s&#39;."\r\n"; 
echo &#39;memory usage:&#39;.(memory_get_usage()/1024)."KB\r\n";
/*
$start = microtime(true); 
for($i=0;$i<100000;$i++){
  $jsonMsg = json_encode($msg);
}
echo &#39;json len:&#39;.strlen($jsonMsg)."\r\n";
$end = microtime(true); 
echo &#39;run time:&#39;.($end-$start).&#39;s&#39;."\r\n"; 
echo &#39;memory usage:&#39;.(memory_get_usage()/1024)."KB\r\n";

$start = microtime(true); 
for($i=0;$i<100000;$i++){
  $packMsg = serialize($msg);
}
echo &#39;php len:&#39;.strlen($packMsg)."\r\n";
$end = microtime(true);
echo &#39;run time:&#39;.($end-$start)."s\r\n";
echo &#39;memory usage:&#39;.(memory_get_usage()/1024)."KB\r\n";*/

Execution results

Analysis comments

The basic results found online are (estimated to be 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

is run in php7, and 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

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
