【问题描述】:
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。)
实际上我在 DOCTYPE 声明之前得到了一个空白字符, 这是非常糟糕的!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,我在之前得到一个零 doctype,我也觉得很奇怪:

这是 foo.php 文件:
<?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 是从哪里来的。
【问题讨论】:
-
你是在你的标题后面直接打电话给
exit()/die()吗?可能正在生成一些输出并阻止它。 -
是的,在标头之后我正在调用退出,这样就不会将任何输出发送到浏览器。这是 PHP 站点上的示例的编写方式。这种方法有什么问题?
-
没什么,你应该这样做。我只是想确定:)
-
尝试使用
curl命令准确检查您的网页返回的内容。我会使用curl --verbose http://url。然后在这里发布你的结果。仅供参考,PHP 手册说“空白行”可以阻止此重定向工作。curl输出应准确显示您的网页正在生成的内容。 -
如果您在包含文件中使用任何 php 结束标记
?>,请确保您没有任何空格。
