How to send Chinese characters from SAP to PHP through RFC? -

i communicating php through rfc using function module.i tried send chinese characters function module php , in php side getting chinese charcters in form of ###### ,

i don't understand side problem ,either php side or sap side? give me suggestion side need focus rectify problem ? or other way send chinese character php?

sap fm code:fn name: zmm_php_to_sap

     t_log-msgty = 'e'.     concatenate p_uname '用户无检料权限' t_log-msgtx separated space.     append t_log. 

php code:

 $login = array ("ashost"=>$row_login1["sap_server"],             "sysnr"=>$row_login1["sap_system_number"],             "client"=>$row_login1["sap_client"],             "user"=>$row_login1["sap_username"],             "passwd"=>$row_login1["sap_password"],             "codepage"=>"8300");  $rfc = saprfc_open ($login);  if(!$rfc){ $error=saprfc_error(); return "the rfc connection has failed following error:".saprfc_error(); exit;} $fce = saprfc_function_discover($rfc,"zmm_php_to_sap"); if(!$fce){     return "the function module has failed.";     return $rfc;     exit;}saprfc_import ($fce,"p_uname","demo-china"); saprfc_table_init ($fce,"t_log");  // call , execute function $rc = saprfc_call_and_receive ($fce); if ($rfc_rc != saprfc_ok){     if ($rfc == saprfc_exception ){         echo ("exception raised: ".saprfc_exception($fce));     } else {         echo ("call error: ".saprfc_error($fce));     }     echo "failure";     exit; } $data_row = saprfc_table_rows ($fce,"t_log");     $log_msg='';     if($data_row != 0 || $data_row != '')        {         ($i=1; $i<=$data_row; $i++)         {         $data = saprfc_table_read ($fce,"t_log",$i);         echo $data['msgtx'];             if($data['msgty'] == "e")             {             $log_msg =$data['msgtx'];             }             if($data['msgno'] == "d")             {             $log_msg ="d";              }          }     } 

when itry print $data['msgtx'] output demo-china ¥Î###®Æ#­­ , how exact chinese characters. in advance.

first of all, should never hardcode character characters/strings in programming language , particularly in abap. in cases sap systems multilingual systems, utulized internationally, therefore symbols hardcoded in 1 environment interpreted differently in environment. under term environment mean logon language, user parameters , et cetera.

hence don't know way how literals treated during call of fm, possible steps can make in case following:

1. first , foremost, convert literal in concatenate statement text-symbol. text symbols recommended way storing character strings in abap.

2. then recommend check whether sap system unicode. can done via system > status > unicode system menu. highly unlikely system non-unicode but, nevertheless, check appreciated.

3. [optional] step optional , makes sense if system non-unicode, nevertheless, useful anyway. set environment codepage chinese statement

   set locale language 1. 

   put statement start fo fm.

4. also sensible ensure unicode system checks enabled in function module. should go go > main program > go > attributes , make sure unicode checks active checkbox active.
