我得到了一个有趣的错误，它说头部已经通过ob_end_flush()发送;运行下面的代码。这就是我得到的错误
警告:无法修改头信息-头已经发送(输出开始于/export/home/ua/games/gamesscripts/login_backend2.php:47)在/export/home/ua/games/gamesscripts/login_backend2.php的第57行现在应该重定向
第47行是ob_end_flush();
编辑:对不起，我在粘贴代码时有点粗心。我现在已经把它按正确的格式排列好了
<?php
include_once('Services_JSON.php');
include 'connect.php';
include_once('functions.php');
error_reporting(E_ALL | E_WARNING | E_NOTICE);
ini_set('display_errors', TRUE);
$json = new Services_JSON();
$username= $_POST["username"];
$password = $_POST["password"];
$check=0;
$query="SELECT * FROM `game_users` WHERE `username` LIKE '$username'";
$result = mysql_query($query)
or
die("<br>Query Error: ".mysql_error());
while($row = mysql_fetch_row($result))
{
$user = $row[2];
$pass = $row[3];
$name = $row[1];
if($username == $user )
{
if($password == $pass)
{
$Day = 86400 + time(); // 1 Day
$name= "name";
$user= "user";
$pass= "password";
ob_start();
//creating cookie for one day
setcookie("username", $user, $Day);
$cookiename = $name.$user;
setcookie("games", $cookiename, $Day);
createSession($user,$cookiename);
ob_end_flush();
$data = array($user, $pass, $name);
$check=1;
flush();
header("Location: http://www.uark.edu/ua/games/gamescripts/Game/Game.html");
die('should have redirected by now');
}
}
}
if($check==0)
{
$data = array("failed", "failed", "failed","failed");
echo $json->encode($data);
}
?>
flush()发送已经排队的报头(在本例中是cookie)。移除flush()呼叫。这段代码将抛出一个关于无法输出第二个头的错误:
<?php
header('a: 1');
flush();
header('b: 2');
?>
您还可以删除输出缓冲-它在这里没有任何用处。这段代码工作得很好，但是:
<?php
ob_start();
header('a: 1');
ob_end_flush();
header('b: 2');
?>
只有flush()发送报头。
确保在开始的<?php标记之前没有任何空格或换行符
