EXAMPLES
       Example #1

	      apache_request_headers(3) example

	      <?php
	      $headers = apache_request_headers();

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

	      The above example will output something similar to:

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

NOTES
       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(3) to see a list of all of the available environment variables.
