原因:在session_start()之前如果有输出内容,会出错,
解决办法:在session_start()之前加上ob_start();
index.php
代码如下:
error_reporting(-1);
ob_start();//不加会出错,无法写入session
register_shutdown_function('close');
echo 1;
session_start();
$_SESSION['password']='mima2ddddddddddddddda2';
function close()
{
if(session_id()!=='')
@session_write_close();
}
?>
index2
index2.Php
代码如下:
error_reporting(-1);
ob_start();//不加会出错,无法读取session
?
echo 1;
session_start();
echo $_SESSION['password'];
var_dump($_SESSION);
?>
index
