How to print all information from an HTTP request to the screen, in PHP
提问by Spike Williams
I need some PHP code that does a dump of all the information in an HTTP request, including headers and the contents of any information included in a POST request. Basically, a diagnostic tool that spits out exactly what I send to a server.
我需要一些 PHP 代码来转储 HTTP 请求中的所有信息，包括头和包含在 POST 请求中的任何信息的内容。基本上，一个诊断工具可以准确地输出我发送到服务器的内容。
Does anyone have some code that does this?
有没有人有一些代码可以做到这一点？

Lastly:
最后：
print_r($_REQUEST);
That covers most incoming items: PHP.net Manual: $_REQUEST
这涵盖了大多数传入项目：PHP.net 手册：$_REQUEST

A simple way would be:
一个简单的方法是：
<?php
print_r($_SERVER);
print_r($_POST);
print_r($_GET);
print_r($_FILES);
?>
A bit of massaging would be required to get everything in the order you want, and to exclude the variables you are not interested in, but should give you a start.
需要进行一些按摩才能按照您想要的顺序获得所有内容，并排除您不感兴趣的变量，但应该给您一个开始。

Nobody mentioned how to dump HTTP headers correctly under any circumstances.
没有人提到如何在任何情况下正确转储 HTTP 标头。
From CGI specification rfc3875, section 4.1.18:
Meta-variables with names beginning with "HTTP_" contain values read from the client request header fields, if the protocol used is HTTP. The HTTP header field name is converted to upper case, has all occurrences of "-" replaced with "" and has "HTTP" prepended to give the meta-variable name.
来自 CGI 规范 rfc3875，第 4.1.18 节：
如果使用的协议是 HTTP，则名称以“HTTP_”开头的元变量包含从客户端请求标头字段读取的值。HTTP 标头字段名称转换为大写，所有出现的“-”都替换为“ ”，并在前面加上“HTTP”以给出元变量名称。
foreach ($_SERVER as $key => $value) {
if (strpos($key, 'HTTP_') === 0) {
$chunks = explode('_', $key);
$header = '';
for ($i = 1; $y = sizeof($chunks) - 1, $i < $y; $i++) {
$header .= ucfirst(strtolower($chunks[$i])).'-';
}
$header .= ucfirst(strtolower($chunks[$i])).': '.$value;
echo $header.'<br>';
}
}

Putting together answers from Peter Baileyand Cmykeryou get something like:
将Peter Bailey和Cmyker 的答案放在一起，您会得到如下结果：
<?php
foreach ($_SERVER as $key => $value) {
if (strpos($key, 'HTTP_') === 0) {
$chunks = explode('_', $key);
$header = '';
for ($i = 1; $y = sizeof($chunks) - 1, $i < $y; $i++) {
$header .= ucfirst(strtolower($chunks[$i])).'-';
}
$header .= ucfirst(strtolower($chunks[$i])).': '.$value;
echo $header."\n";
}
}
$body = file_get_contents('php://input');
if ($body != '') {
print("\n$body\n\n");
}
?>
which works with the php -Sbuilt-in webserver, which is quite a handy feature of PHP.
它与php -S内置的网络服务器一起工作，这是 PHP 的一个非常方便的功能。

If you want actual HTTP Headers (both request and response), give hurl.ita try.
如果您想要实际的 HTTP 标头（请求和响应），请尝试hurl.it。
You can use the PHP command apache_request_headers()to get the request headers and apache_response_headers()to get the current response headers. Note that response can be changed later in the PHP script as long as content has not been served.
您可以使用 PHP 命令apache_request_headers()获取请求标头和apache_response_headers()当前响应标头。请注意，只要内容尚未提供，就可以稍后在 PHP 脚本中更改响应。

file_get_contents('php://input') will not always work.
file_get_contents('php://input') 并不总是有效。
I have a request with in the headers "content-length=735" and "php://input" is empty string. So depends on how good/valid the HTTP request is.
我在标题中有一个请求，其中“content-length=735”和“php://input”是空字符串。所以取决于 HTTP 请求的好坏程度。

The problem was, in the URL i wrote http://my_domaininstead of https://my_domain
问题是，在 URL 中我写了http://my_domain而不是https://my_domain

in addition, you can use get_headers(). it doesn't depend on apache..
此外，您可以使用get_headers()。它不依赖于 apache ..
print_r(get_headers());
