PHP获取http请求的头信息实现步骤

php手册提供了现成的函数：

getallheaders

(php 4, php 5)

getallheaders — fetch all http request headers

说明

array getallheaders ( void )

fetches all http headers from the current request.

this function is an alias for apache_request_headers(). plea read theapache_request_headers() documentation for more information on how this function works.

返回值

an associati高兴的反义词ve array of all the http headers in the current request, orfal on failure.

example #1 getallheaders() example


复制代码 代码如下:

<?php

foreach (孙俪新电视剧getallheaders() as $name => $value) {

echo “$name: $value\n”;

}

?>

不过这个函数只能在apache环境下使用，iis或者nginx并不支持，可以通过自定义函数实揠苗助长的道理现


复制代码 代码如下:

<?php

<span class=htmcos图像l>if (!f做什么最挣钱unction_exists(‘getallheaders’))

{

function getallheaders()

{

foreach ($_rver as $name => $value)

{

if (substr($name, 0, 5) == ‘http_’)

{

$headers[str_replace(‘ ‘, ‘-‘, ucwords(strtolower(str_replace(‘_’, ‘ ‘, substr($name, 5)))))] = $value;

}

}

return $headers;

}

}</span>

?>

好了，看看都打印出了啥吧


复制代码 代码如下:

<?php

print_r(getallheaders());

获得结果：


复制代码 代码如下:

array

(

[accept] => */*

[accept-language] => zh-cn

[accept-encoding] => gzip, deflate

[ur-agent] => mozilla/4.0 (compatible; msie 7.0; windows nt 5.1; trident/4.0; .net clr 2.0.50727)

[host] => localhost
