$ _ SERVER ['http _ token']

Getallheaders () ['token'];

getallheadersYesapache_request_headersIs not usednginxServer, write a simplefunction.

Function request_header ($ key = null) {$ all_headers = []; foreach ($ _ SERVER as $ name = >$ value) {if (substr ($ name, 0, 5) = 'http _ ') {$ all_headers [str_replace ('','-', ucwords (strtolower (str_replace (' _ ','', substr ($ name, 5)] = $ value ;}} return is_null ($ key )? $ All_headers: (isset ($ all_headers [$ key])? $ All_headers [$ key]: null);} request_header ('token'); // if no key is passed, all heads arrays are returned.

All REQUEST data is stored in $ _ REQUEST
