我一直想知道,如果一个PHP会话超时执行脚本的中部期间,将在$ _SESSION数组中的内容仍然可用,直到脚本执行结束？例如:

session_start();

if(! isset($_SESSION['name'])) {
    echo 'Name is not set';
    exit;
}

// imagine there is a bunch of code here and that the session times out while
// this code is being executed

echo 'Name is ', $_SESSION['name']; // will this line throw an error?

将会话变量复制到本地作用域是否切实可行,以便稍后在脚本中读取它们而不必继续检查会话超时？就像是:

session_start();

if(isset($_SESSION['name'])) {
    $name = $_SESSION['name'];
} else {
    echo 'Name is not set';
    exit;
}

// bunch of code here

echo 'Name is ', $name;
