我有代碼以下兩個片段做工精細..簡單的會話變量超級難倒
<?php session_start();
$query = '23';
$_SESSION['testing'] = $query;
echo $_SESSION['testing'] . "<html><br></html>";
echo "<html><a href='http://www.nhl-statistics.com/scripts/test2.php'>click</a></html>"
?>
這個環節太..
<?php session_start();
echo $_SESSION['testing'] . "<html><br></html>";
echo "<html><a href='http://www.nhl-statistics.com/scripts/test2.php'>click</a></html>"
session_destroy();
?>
但是..我將在後兩頁這同樣的方法不工作，並希望你們可以告訴我爲什麼
<?php session_start();
?>
<script type="text/javascript">
function destroyit()
{
<?php session_destroy(); ?>
}
</script>
</head>
<body>

</div>
<div id='contenttext' class='contenttext'>
<?php $username="a75sdadmin";
$password="1dBasdns2";
$database="a75asdesting";
$pword = $_REQUEST['pword'];
$uname = $_REQUEST['uname'];
mysql_connect('myssd.com',$username,$password);
@mysql_select_db($database) or die("Unable to select database");
$query = mysql_query("SELECT * FROM `username` WHERE `password` = '$pword' AND `username` = '$uname'");
$exsists = 0;
WHILE($rows = mysql_fetch_array($query)){
$exsists = 1;
break;
}
if ($exsists){
$_SESSION['usern23']=$uname;
$_SESSION['logged']=1;
header('Location: logged2.php');
}
mysql_close();
?>
</div>
</body>
</html>
會話變量不會發布到此pa GE出於某種原因..（logged2）
<?php session_start();
echo 'welcome, ' . $_SESSION['usern23'];
?>

你的javascript函數函數destroyit（）是什麼點？當頁面被渲染時，它將只是一個空的函數... PHP代碼不是簡單地通過調用一個javascript函數來執行，如果這就是你想要做的事情......你需要調用一個PHP腳本網絡服務器做到這一點 – 2011-03-16 16:53:28
