未设置会话变量会停止执行
我对这段代码非常着迷，并将其范围缩小到 unset 函数。当我对会话变量调用 unset 时，PHP 不会执行超出该点的任何操作。有人可以帮忙吗？
public static function print_session_notification() {
if( isset( $_SESSION['notification'] )) {
$session_notification = $_SESSION['notification'];
$output = '<div class="error">';
$output .= $_SESSION['notification'];
$output .= '</div>';
unset( $_SESSION['notification'] );
return $output;
}
}
我调用 print notification::print_session_notification();来自标头包含。标头包含由函数调用。 $notification 对象在调用头文件的函数中是全局的。
I have been going crazy over this piece of code and narrowed it down to the unset function. When I call unset on the session variable, PHP doesn't execute anything beyond that point. Can someone please help?
public static function print_session_notification() {
if( isset( $_SESSION['notification'] )) {
$session_notification = $_SESSION['notification'];
$output = '<div class="error">';
$output .= $_SESSION['notification'];
$output .= '</div>';
unset( $_SESSION['notification'] );
return $output;
}
}
I call print notification::print_session_notification(); from a header include. The header include is called by a function. The $notification object is global in the function that calls the header file.

我通过向构造添加一个方法并将会话值分配给公共属性来解决该问题。谢谢你们的帮助！
I fixed the issue by adding a method to the construct and assigning the session values to public properties. Thanks for your help guys!!!
请确保在标头上设置了 session_start() 函数，并将 register_globals 设置为“ON”。
有关更多信息，请阅读 http://www.php.net/manual/en/function.unset.php
Please make sure that you set session_start() function on you header and set register_globals to "ON"
