php 怎么返回的是乱码呢?

以下是返回结果:

var hq_str_sh601006="������·,6.360,6.350,6.330,6.390,6.320,6.320,6.330,25996996,165270113.000,1055700,6.320,412700,6.310,524900,6.300,116900,6.290,131500,6.280,93700,6.330,340020,6.340,728100,6.350,668100,6.360,928814,6.370,2016-08-26,15:00:00,00";

以下是代码,也写了个编码了,怎么还是乱码呢?:

<?php


$url = "http://hq.sinajs.cn/list=sh601006";

$info = getCurlData($url);

echo $info . "</br>" ;



function getCurlData($url)
{
    if (empty ( $url ))
    {
        return false;
    }

    $ch = curl_init ();
    curl_setopt ( $ch, CURLOPT_URL, $url );
    curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt ( $ch, CURLOPT_HEADER, 0 );
    $output = curl_exec ( $ch );
    curl_close ( $ch );
    return $output;

}

原站是gbk

最后改成 return iconv('gbk', 'UTF-8', $output);就ok了吧关键原来的是GBK的网页
