PHP session使用

??? 因为以前是学java的,现在使用php做项目觉得特别不习惯,特别是php的session机制,感觉比java落后很多。

?

??? 1、php使用session,是通过在各个页面传递session id来标识的。默认是通过cookie来传递,所以在php.ini配置文件中一定要开启支持cookie功能。

?

??? 2、要在配置文件中设置session.save_path,这是session临时文件保存的路径

?

??? 3、每次需要在页面中使用session时,要先session.start();开启session

?

??? 4、session的接收页面需要有header('Content-type: text/html; charset=utf-8');来传递session id
