php - 标头函数不起作用PHP

Question

成功注册后我重定向了一个页面，代码工作正常，但标题功能不工作&页面不重定向。页面未重定向。我的代码如下

  <?php
error_reporting(E_ALL ^ E_NOTICE);
error_reporting(E_ALL ^ E_WARNING);

//include("lib/local_config.php");
include("lib/config.php");


$activation=md5(uniqid(rand(), true));

if(isset($_POST["tb_submit"]))
{
    $fname=$_POST["tb_fname"];
    $email=$_POST["tb_email"];
    $pass=$_POST["tb_pass"];
    $repass=$_POST["tb_repass"];
    $contact=$_POST["tb_contact"];

    $select_email=mysql_query("select email from user_reg where email='$email'");
    $rows=mysql_fetch_row($select_email);
    $e_id=$rows[0];

    if(!$email==$e_id && $pass==$repass)
    {
        $insert="insert into user_reg ( fname ,email ,password ,contact,Activation)    values      ('$fname' , '$email' , '$pass' ,'$contact' ,'$activation')";
        $insert_query=mysql_query($insert);

        if(mysql_affected_rows($connect) == 1)
        //if(mysql_affected_rows() == 1)
        {
            $to = $_POST['tb_email'];
            $subject = "Fundu App Creator - Registration confirmation mail ";
            $message = <<<DEMO

输出内容后不能发送标头。在这里，您在 PHP 标记之前输出空格：

  <?php
^^ remove this whitespace

检查你的错误日志，你会发现：

警告：无法修改标头信息 - 标头已发送

您应该有一个exit;重定向代码之后。看到这个评论。

尝试，使用输出缓冲区

<?php ob_start() ?>

在这段代码的顶部

用这个。它对我有用。将此函数放在代码的顶部：

function move_to(){
    header("Location:page_example.php");
}

并在任何地方调用该函数：

move_to()

使用 headers_sent 函数来检测问题。 http://php.net/manual/en/function.headers-sent.php

检查是否或已发送标头。

一旦标题块已经发送，您就不能使用 header() 函数添加更多标题行。使用此功能，您至少可以防止收到与 HTTP 标头相关的错误消息。另一种选择是使用输出缓冲。

// An example using the optional file and line parameters, as of PHP 4.3.0
// Note that $filename and $linenum are passed in for later use.
// Do not assign them values beforehand.
if (!headers_sent($filename, $linenum)) {
    header('Location: http://www.example.com/');
    exit;

// You would most likely trigger an error here.
} else {

    echo "Headers already sent in $filename on line $linenum\n" .
          "Cannot redirect, for now please click this <a " .
          "href=\"http://www.example.com\">link</a> instead\n";
    exit;
}

对于您的代码：

<?php
error_reporting(E_ALL ^ E_NOTICE);
error_reporting(E_ALL ^ E_WARNING);

//include("lib/local_config.php");
include("lib/config.php");


$activation=md5(uniqid(rand(), true));

if(isset($_POST["tb_submit"]))
{
    $fname=$_POST["tb_fname"];
    $email=$_POST["tb_email"];
    $pass=$_POST["tb_pass"];
    $repass=$_POST["tb_repass"];
    $contact=$_POST["tb_contact"];

    $select_email=mysql_query("select email from user_reg where email='$email'");
    $rows=mysql_fetch_row($select_email);
    $e_id=$rows[0];

    if(!$email==$e_id && $pass==$repass)
    {
        $insert="insert into user_reg ( fname ,email ,password ,contact,Activation)    values      ('$fname' , '$email' , '$pass' ,'$contact' ,'$activation')";
        $insert_query=mysql_query($insert);

        if(mysql_affected_rows($connect) == 1)
        //if(mysql_affected_rows() == 1)
        {
            $to = $_POST['tb_email'];

            }
        }
        else
        { // If it did not run OK.
            header("location:index.php?er=2");
        //use exit after redirection request
        exit;
        }
    }
}

?>

ps：也可以看看“DEMO”；在您的代码中的位置，它应该在行首，不是吗？重定向后使用退出。在你之前删除空格
