apache_request_headers

(PHP 4 >= 4.3.0, PHP 5)

apache_request_headers -- Fetch all HTTP request headers

说明

array apache_request_headers ( void )

Fetches all HTTP requests from the current request.

此函数仅在 PHP 作为 Apache 模块安装时才可使用。

返回值

An associative array of all the HTTP headers in the current request, or FALSE on failure.

例

例子 1. apache_request_headers() example

<?php
$headers = apache_request_headers();

foreach ($headers as $header => $value) {
    echo "$header: $value <br />\n";
}
?>

上例的输出类似于：

Accept: */*
Accept-Language: en-us
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0
Host: www.example.com
Connection: Keep-Alive

注释

注: Prior to PHP 4.3.0, apache_request_headers() was called getallheaders(). After PHP 4.3.0, getallheaders() is an alias for apache_request_headers().

注: You can also get at the value of the common CGI variables by reading them from the environment, which works whether or not you are using PHP as an Apache module. Use phpinfo() to see a list of all of the available environment variables.

注: 自 PHP 4.3.3 起也可以在 Netscape/iPlanet/SunONE 服务器的 NSAPI server module 中使用本函数。
