擷取http請求的頭資訊。
PHP手冊提供了現成的函數：
getallheaders
(PHP 4, PHP 5)
getallheaders—Fetch all HTTP request headers
說明
arraygetallheaders(void)
Fetches all HTTP headers from the current request.
This function is an alias forapache_request_headers(). Please read theapache_request_headers()documentation for more information on how this function works.
傳回值
An associative array of all the HTTP headers in the current request, orFALSEon failure.
Example #1getallheaders()example
<?php
foreach (getallheaders() as $name => $value) {
echo "$name: $value\n";
}
?>
不過這個函數只能在apache環境下使用，iis或者nginx並不支援，可以通過自訂函數實現
<?php
<span class="html">if (!function_exists('getallheaders'))
{
function getallheaders()
{
foreach ($_SERVER 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，看看都列印出了啥吧
<?php
print_r(getallheaders());
獲得結果
