$proquery ="select * from #@__keyproduct where typeid='".$id."' order by corank asc";

$dsql->setquery($proquery);
$dsql->execute();
$i=0;
while($row = $dsql->getarray()) {

$arrystr.='{"id":"'.$row["id"].'","title":"'.$row["goodstitle"].'","goodstitle":"'.$row["goodstitle"].'","price":"'.$row

["price"].'","imgurl":"'.$row["imgurl"].'","goodsurl":"'.$row["goodsurl"].'","brandname":"'.$row

["brandname"].'","brandurl":"'.$row["brandurl"].'"},';

$i++;
}

if($i>0){ $arrystr=substr($arrystr,0,$arrystr.lenght-1); }
如果这样写
$a='{"status":"1","result":['.$arrystr.'],"moreurl":"'.$moreurl.'"}';
ajax返回 {"status":"1","result":[],"moreurl":"http:\/\/"}
result 是空的

如果下面这样写就是正常
//$a='{"status":"1","result":[{"id":"1","title":"补水润肤膏真的很好很补水皮肤有弹性","goodstitle":"补水润肤膏真的很好很补水皮肤有弹","price":"59.9","imgurl":"http:///sadas213/","goodsurl":"http:///uploads/allimg/c131205/

13v23912150-114l_lit.jpg","brandname":"","brandurl":"http:///dsadasdas/"},{"id":"2","title":"补水润肤

222","goodstitle":"补水润肤

222","price":"59.9","imgurl":"http:///sadas213/","goodsurl":"http:///uploads/allimg/c131205

/13v23912150-

114l_lit.jpg","brandname":"","brandurl":"http:///dsadasdas/"}],"moreurl":"http://jianfei.ecoo.com.cn/shuig

uo/"}';

$a = iconv("gbk", "utf-8", $a);
$a=json_decode($a, true);
echo json_encode($a);

请大神们指教一下谢谢！

回复讨论(解决方案)

$r['a'] = 123;echo json_encode($r); //得到 {"a":123}$a[] = $r;$a[] = $r;$a[] = $r;echo json_encode($a); //得到 [{"a":123},{"a":123},{"a":123}]

你应该知道怎么写了吧？

虽然 php 的 json 函数只支持 utf-8 编码，但你可以要求数据库返回 utf-8 编码的数据

版主您好我将代码修改成这样可还是不行我是学.net的 Php实在太差麻烦您在指导一下谢谢
$a=array();
while($row = $dsql->GetArray()) {
$a[]= $row;
}
$a='{"status":"1","result":'.json_encode($a).',"moreUrl":"'.$moreurl.'"}';
$a = iconv("gbk", "UTF-8", $a);
$a=json_decode($a, true);
echo json_encode($a);

AJAX返回 {"status":"1","result":[],"moreUrl":"http:\/\/"}
result 是空的

1、你用的是什么数据库？不会是 Access 吧？
2、如果你无法让数据库返回 utf-8 编码的数据，可以这样

function gtou($s) { return iconv('gbk', 'utf-8', $s); }$a=array();while($row = $dsql->GetArray()) {	  $a[]= array_map('gtou', $row); }

3、这样构造输出数据

$res = array(  'status' => '1',  'result' => $a,  'moreUrl' => $moreurl,);echo join_encode($res);

版主您好这样写输出也是对的
但
AJAX返回 {"status":"1","result":[],"moreUrl":"http:\/\/"}
result 是空的

我的QQ 272718467 要不您加下我的QQ指导一下或者关注我一下可以吗？

这样直接返回数据库读出的数据 AJAX 就可以接到 result
//$a='{"status":"1","result":[{"id":"1","title":"补水润肤膏真的很好很补水皮肤有弹性","goodsTitle":"补水润肤膏真的很好
很补水皮肤有弹
性","price":"59.9","imgUrl":"http:///sadas213/","goodsUrl":"http:///uploads/allimg/c131205/
13V23912150-114L_lit.jpg","brandName":"","brandUrl":"http:///dsadasdas/"},{"id":"2","title":"补水润肤
222","goodsTitle":"补水润肤
222","price":"59.9","imgUrl":"http:///sadas213/","goodsUrl":"http:///uploads/allimg/c131205
/13V23912150-114L_lit.jpg","brandName":"","brandUrl":"http:///dsadasdas/"}],"moreUrl":"http://shuig
uo/"}';

我是mysql数据库
