php - Port Number Being Repeated Twice? -

i have small bug in construction of url, i've setup test when not using port:80 , reason if use port:8080 applying port number twice reason in code cant explain it.

public function get_full_url() {     /** $_server **/     $server = self::get('server');      $page_url = 'http';     if(isset($server['https']) , $server['https'] == 'on')     {         $page_url .= 's';     }      $site_domain = (isset($server['http_host']) , trim($server['http_host']) != '') ? $server['http_host'] : $server['server_name'];      $page_url .= '://';     if($server['server_port'] != '80')     {         $page_url .= $site_domain.':'.$server['server_port'].$server['request_uri'];     }     else     {         $page_url .= $site_domain.$server['request_uri'];     }      return $page_url; } 

$_server['http_host'] contain port number set in host: header
