getallheaders -- Fetch all HTTP request headers
Description
array getallheaders (void)
This function returns an associative array of all the HTTP headers in the current
request.
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 environment variables
defined this way.
