function gtou($s) { return iconv('gbk', 'utf-8', $s); }
$proquery ="select * from pro where typeid='".$id."' order by corank asc";
 $dsql->SetQuery($proquery); 
$dsql->Execute(); 
$a=array();
 while($row = $dsql->GetArray())
 {
 $a[]= array_map('gtou', $row); 
} 
$res = array(
 "status" => "1",
 "result" => $a,
 "moreUrl" => $moreurl, );
 echo json_encode($res);
 

The returned value is {"status": "1", "result": [], "moreUrl": "http: \/wcn"}. The result is null.
If
Echo json_encode ($ res );
Change to the following
// Echo '{"status": "1", "result": [{"id": "1", "typeid": "111", "goodstitle ": "\ u8865 \ u6c34 \ u6da6 \ u80a4 \ u818f \ Alibaba \ u7684 \ Alibaba \ u597d \ Alibaba \ u8865 \ Alibaba \ u76ae \ u80a4 \ u6709 \ u5f39 \ u6027 ", "goodsurl": "http: \/www. \/uploads \/allimg \/c131205 \/13V23912150-114L_lit.jpg "," brandtitle ":" \ u7f8e \ u5b9d \ u83b2 "," brandurl ":" http :\// www. \/dsadasdas \/"," imgurl ":" http: \/www. \/sadas213 \/"," price ":" 59.9 "," corank ":" 1 "},{" id ":" 2 "," typeid ": "111", "goodstitle": "\ u8865 \ u6c34 \ u6da6 \ u80a4222", "goodsurl": "http: \ // www. \/uploads \/allimg \/c131205 \/13V23912150-114L_lit.jpg "," brandtitle ":" \ u7f8e222 "," brandurl ":" http: \ // www. \/dsadasdas \/"," imgurl ":" http: \/www. \/sadas213 \/"," price ":" 59.9 "," corank ":" 1 "}]," moreUrl ":" http: \/jianfei. \/shuiguo \/"} '; that's correct.
