是否应该在 PHP 文件的 DOCTYPE 之前放置一个包含？

我有一个包含导致配置文件的文件，我认为该文件会阻止网站加载。如果删除这包括页面加载（由于缺少功能而出现错误），但是一旦我把它放回去，它就会再次中断。

请注意。在 DOCTYPE 之前，我还有许多其他站点，它们都运行良好。它们导致的配置文件完全相同，这告诉我它不是配置文件中的编码。

所以最上面的一行现在看起来像这样：

<? include('config.php'); ?><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

然后配置文件如下所示：

 <?
// WEBSITE SETUP
$config_website_code = "FR"; // .net IS Q, EVERYTHING ELSE IS GEO CODE
$config_db_error = 1; // IS THE DATABASE WORKING? 0 IS NO
$config_website_url = "http://www.lektronix.fr";
$config_website_short_url = "lektronix.fr";

// GOOGLE ANALYTICS
$config_analytics_code = "<script type=\"text/javascript\">\n";
$config_analytics_code .= "var _gaq = _gaq || [];\n";
$config_analytics_code .= "_gaq.push(['_setAccount', 'UA-4257220-56']);\n";
$config_analytics_code .= "_gaq.push(['_trackPageview']);\n";
$config_analytics_code .= "(function() {\n";
$config_analytics_code .= "var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;\n";
$config_analytics_code .= "ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';\n";
$config_analytics_code .= "var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);\n";
$config_analytics_code .= "})();\n";
$config_analytics_code .= "</script>\n";

// ASSIGN GEO BASED ON THEIR IP
include('assign_geo.php'); 

// ASSIGN THEIR LANGUAGE
include('assign_language.php'); 

// DEFINE THE CONTENT THEY SEE
include('assign_content.php');

// COMMON PAGE FUNCTIONS
include('functions.php'); 

// HEADER AND DESCRIPTION TAGS
include('assign_meta_data.php');  
?>

这与其他工作网站相同，配置文件中包含的文件也相同。

我从头文件和索引文件中删除了所有内容，只回显“hello world”；

这已加载并且是正确的。

i then began placing code back in but the first line i placed back in was the include before the doctype and this broke the website again.

Yes you can put PHP code before the DOCTYPE in a file it will not cause any problems. Looking at your code and from what you've told me the problem should be with your code in one of the files being called from the config file. My guess is the Functions file. go check that out. A little debugging will go a long way.
