</head>


<?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;

Finally change it to return iconv('gbk', 'UTF-8', $output);It will be ok. The key is the original webpage of GBK
