我正在调用 header('Location: http://foo.com/foo/ '); 在使用包含函数调用(无输出)的文件调用 include() 之后的文件中。每当我调用 include() 时,PHP header() 重定向都不起作用。这只发生在服务器上。无论我包含哪个 PHP 文件,都会发生这种情况。(本地文件在开发过程中上传到服务器。)


好吧,实际上我在 DOCTYPE 声明之前得到了一个空白字符,这非常糟糕!无论我包含一个还是两个文件,我都会得到一个空白字符。

另一方面,当我在 foo.php 中不包含任何文件时,我在 doctype 之前得到一个零,我也觉得这很奇怪:

这是文件 foo.php:

    <?php
        session_start();

        // I added the require just to make sure nothing is being printed there
        // (an error for example)
    //    require_once('include/connect.php');
    //   require_once('include/util.php');

        header("Location: " . "http://www.google.com");
        exit;
    ?>

我真的很想知道文件开头的 0 来自哪里。

强烈建议不要对非模板文件使用 php 的结束标记。

<?php //VERY first line, no whit space
  // code
  // NO ?> *anywhere*

通常它是 ?> 之后的换行符,这会导致您的错误。
