Description
array 
apache_request_headers ( void )
     apache_request_headers() returns an associative
     array of all the HTTP headers in the current request.  This is only
     supported when PHP runs as an Apache
     module.
    
     
| 例子 1. apache_request_headers() example | 
<?php$headers = apache_request_headers();
 
 foreach ($headers as $header => $value) {
 echo "$header: $value <br />\n";
 }
 ?>

    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: 
  From PHP 4.3.3 on you can use this function with the
  NSAPI server module in Netscape/iPlanet/SunONE
   webservers, too.
