PHP Manual: Fetch all HTTP request headers

Description

array nsapi_request_headers ( void )

nsapi_request_headers gets all the HTTP headers in the current request. This is only supported when PHP runs as a NSAPI module.

Note:
Prior to PHP 4.3.3, getallheaders was only available for the Apache servers. After PHP 4.3.3, getallheaders is an alias for nsapi_request_headers if you use the NSAPI module.

Note:
You can also get at the value of the common CGI variables by reading them from the $_SERVER superglobal, which works whether or not you are using PHP as a NSAPI module.

Return Values

Returns an associative array with all the HTTP headers.

Examples

Example #1 nsapi_request_headers example


<?php
$headers = nsapi_request_headers();

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