我对php相对较新，但我遇到了一个即将让我发疯的错误。
我正在努力创建一个网页，让您浏览服务器上的文件。
但是，出于某种原因，$_SESSION 变量保持自身设置，即使在浏览器重新启动后......
拜托，我求求你，在我发疯之前告诉我为什么会这样。
这是我的代码：
<html>
<?php
session_start();
if(!isset($_GET['location'])) {
header('Location: ?location=G:');
session_unset();
}
/* THIS IS WHERE THE BUG OCCURS. THIS VARIABLE SHOULD BE EMPTY ON BROWSER OPEN!!!! ?!?!?!?! I HAVE ADDED NOTHING TO SESSION YET*/
var_dump($_SESSION);
if(!isset($_SESSION['path'])) {
$_SESSION['path'] = array();
$_SESSION['path'][0] = $_GET['location'];
}
echo '<br><br><br><br><br><br>';
//* If user presses back and isn't in home folder, return to previous folder... *//
if(isset($_GET['back']) && $_GET['back'] == true && sizeof($_SESSION['path']) > 0) {
unset($_SESSION['path'][sizeof($_SESSION['path'])-1]);
$_GET['location'] = $_SESSION['path'][sizeof($_SESSION['path'])-1];
header ('Location: ?back=false');
} else {
//*However if user hasn't pressed back make sure that session is properly updated with location *//
if($_SESSION['path'][sizeof($_SESSION['path'])-1] != $_GET['location']) {
array_push($_SESSION['path'], $_GET['location']);
}
}
//*Now build the link from the session path array*//
$full_link = '';
for($i = 0; $i < sizeof($_SESSION['path']); $i++) {
$full_link .= $_SESSION['path'][$i];
$full_link .= '/';
}
//*Get all files from link path*//
$filesbrowsed = glob($full_link . '*');
?>
<head>
<meta charset "utf8">
<title>File Browser</title>
<link href="filebrowserstyle.css" rel="stylesheet" type="text/css">
</head>
<body>
<header>
<ul class = "navigation">
<li><a href = "">Home</a></li>
<li><a href = "?back=true">Back</a></li>
<li><a href = ""></a></li>
<li><a href = ""></a></li>
</ul>
</header>
<div class = 'current_files'>
<?php
//* Now display all files in current path *//
for($i = 0; $i < sizeof($filesbrowsed); $i++) {
$filename = substr($filesbrowsed[$i], strlen($full_link), strlen($filesbrowsed[$i]) - strlen($full_link));
echo '<div><a href = "?location=' . $filename . '/' . '">' . $filename . '</a></div>';
}
?>
</div>
</body>
</html>
提前谢谢大家!!
您应该在将用户重定向到另一个位置之前取消设置会话。
<html>
<?php
session_start();
if(!isset($_GET['location'])) {
session_unset();
session_destroy();
header('Location: ?location=G:');
}
/* THIS IS WHERE THE BUG OCCURS. THIS VARIABLE SHOULD BE EMPTY ON BROWSER OPEN!!!! ?!?!?!?! I HAVE ADDED NOTHING TO SESSION YET*/
var_dump($_SESSION);
删除会话中的所有数据：
$_SESSION = [];
