如何让ob_start()正常工作

标签: php html buffer

我收到一条错误消息:

警告:无法在/home/content/21/10941021/html/register.php中修改标题信息 - 已经发送的标题(/home/content/21/10941021/html/index.php:4中的输出开始)在第66行

我想我需要放一个ob_start()来使缓冲正常工作,但我无法理解它。问题包括我的代码:

<div class="lower-body">
<div class="left-lower">Create an account</div>
<div id="account-first">
<?php ob_start();
if (isset($_GET['success']) && empty($_GET['success'])){
    echo 'You\'ve been registered successfully!';
    echo 'Please check email and activate account!'; 
}else {

if(empty($_POST) === false && empty($errors) === true){
    $register_data = array(
        'firstname' => $_POST['firstname'],
        'lastname'  => $_POST['lastname'],
        'username'  => $_POST['username'],
        'password'  => $_POST['password'],
        'email'     => $_POST['email'],
        'zipcode'   => $_POST['zipcode']
        );

    register_user($register_data);
    header('Location: register.php?sucess');
    exit();
} else if(empty($errors) === false){
    echo output_errors($errors);
    }
}
ob_end_flush();?>

然后第4行是:

<?php
ob_start();
include 'includes/overall/head.php';
?>

任何想法? 非常感谢!

答案 0 :(得分:0)

header('Location: register.php?sucess');应该在echo

之类的输出之前

编辑1: 在PHP代码的开头使用ob_start();,在最后使用ob_end_flush();,应该解决问题。

编辑2:使用此

<?php ob_start(); ?>
<div class="lower-body">
<div class="left-lower">Create an account</div>
<div id="account-first">
<?php
...
...
ob_end_flush();
?>
