(PHP 4 >= 4.3.0, PHP 5)
apache_request_headers — Fetch all HTTP request headers
Fetches all HTTP request headers from the current request.
、 仅在将 PHP 安装为 Apache 模块时，支持此函数。
An associative array of all the HTTP headers in the current request, or FALSE on failure.
| 版本 | 说明 |
|---|---|
| 4.3.3 |
|
| 4.3.0 | 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(). |
Example #1 apache_request_headers() example
<?php
$headers = apache_request_headers();
foreach ($headers as $header => $value) {
echo "$header: $value <br />\n";
}
?>
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
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.
