更新日志

版本	说明
5.4.0	This function became available under FastCGI. Previously, it was supported only when PHP was installed as an Apache module.
4.3.3	Note: 从 PHP 4.3.3 起，也可在 Netscape/iPlanet/SunONE Web 服务器的 NSAPI 服务器模块使用此函数。

范例

Example #1 apache_request_headers() example


<?php
$headers = apache_request_headers();

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

以上例程的输出类似于：

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

注释

Note:
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.
