session start之后是先open,在read, 如果期间有$_SESSON['NAME']='A'这时候应该在内存中。 最后脚本执行完成后(可用register_shutdown_function)测试,再write,再close。 但是如果在write之前这个sessionid被删除掉了,那会怎样? ps:按道理是不是open的时候lock了,就不会被删除了,到底是怎样?

PHP 的 session_start() 函数执行时相当于完成了会话的 open 和 read 两个步骤,而 session_commit() 执行时相当于进行了会话的 write 和 close 两个步骤,与 session_write_close() 函数作用是一致的。 回到最初遇到的问题上,当 PHP 的 SESSION 开启后,进程会对会话的临时文件加锁,以保证同一时刻此文件只被...
现在,session_start()函数可以接收一个数组作为参数,可以覆盖php.ini中session的配置项。 比如,把cache_limiter设置为私有的,同时在阅读完session后立即关闭。 session_start(['cache_limiter' => 'private', 'read_and_close' => true, ]); $_SERVER[“REQUEST_TIME_FLOAT”] 这个是用来统计服务请求时间的,...

Session Alternatives WordPress itself specifically doesn’t use PHP sessions, and the correct method to store session data is to use the database. Additionally, many eCommerce solutions have converted to using this updated method. If checking through your site’s code you find a plugin or theme...

Theclosemethod, like theopenmethod, can also usually be disregarded. For most drivers, it is not needed. Thereadmethod should return the string version of the session data associated with the given$sessionId. There is no need to do any serialization or other encoding when retrieving or storing...
