标头( "location:" );无法联机工作。

Question

header("location："( 无法在线工作，但它适用于本地主机。 我也尝试将完整的 URI 放在标头中，但仍然不起作用。只需跳过标题("位置："(，但它会写出回声。为什么它会跳过标题(位置(;但是打印回声"你好"，有人可以帮我吗？:)

<?php
include('header.php');
session_start();
if(!isset($_SESSION["login_user"])) {
header("location:login-form.php");
echo "hellooooo";
exit();
}
?>

<?php
if (isset($_GET['page'])) {
$p = $_GET['page'];

switch ($p) {
case 'job-application':
include ('job-application.php');
break;
case 'company-application':
include ('company-application.php');
break;
case 'edit-text':
include ('edit-text.php');
break;
case 'school-time':
include ('school-time.php');
break;
case 'care-time':
include ('care-time.php');
break;
case 'cleaning-time':
include ('cleaning-time.php');
break;
case 'economy-time':
include ('economy-time.php');
break;
case 'restaurant-time':
include ('restaurant-time.php');
break;
case 'construction-time':
include ('construction-time.php');
break;
case 'retail-time':
include ('retail-time.php');
break;
default:
include ('job-application.php');
break;
}
} else {
include ('job-application.php');
}
?>
<?php include('footer.php'); ?>

Answer 1

试试这个：

<?php
session_start();
if(!isset($_SESSION["login_user"])) {
header("location: http/https://your_site/path_to/login-form.php");
echo "hellooooo";
exit();
}
include('header.php');
if (isset($_GET['page'])) {
$p = $_GET['page'];

switch ($p) {
case 'job-application':
include ('job-application.php');
break;
case 'company-application':
include ('company-application.php');
break;
case 'edit-text':
include ('edit-text.php');
break;
case 'school-time':
include ('school-time.php');
break;
case 'care-time':
include ('care-time.php');
break;
case 'cleaning-time':
include ('cleaning-time.php');
break;
case 'economy-time':
include ('economy-time.php');
break;
case 'restaurant-time':
include ('restaurant-time.php');
break;
case 'construction-time':
include ('construction-time.php');
break;
case 'retail-time':
include ('retail-time.php');
break;
default:
include ('job-application.php');
break;
}
} else {
include ('job-application.php');
}
?>
<?php include('footer.php'); ?>
