Note:
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().
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.
Note: As of PHP 4.3.3 you can use this function with the
NSAPI server module in Netscape/iPlanet/SunONE
webservers, too.
