Php method for getting header information for HTTP requests

<?phpforeach (Getallheaders () as $name = + $value) {echo "$name: $value \ n";}? >

This function can only be used in Apache environment, IIS or Nginx is not supported, can be implemented by custom functions.

<?phpif (!function_exists (' getallheaders ')) {function getallheaders () {foreach ($_server as $name = = $value) {if ( substr ($name, 0, 5) = = ' Http_ ') {$headers [Str_replace (', '-', Ucwords (Strtolower (' _ ', ' ", Str_replace ($name, 5)) )])] = $value;}} return $headers;}}? >

Look at the printed results:

<?phpprint_r (Getallheaders ());

Get results:

Array ([Accept] = */*[accept-language] = zh-cn[accept-encoding] = gzip, deflate[user-agent] = mozilla/ 4.0 (compatible; MSIE 7.0; Windows NT 5.1; trident/4.0;. NET CLR 2.0.50727) [Host] = localhost[connection] = keep-alive)
