YAHOO.Finance.SymbolSuggest.ssCallback(
{
    "ResultSet": {
        "Query": "ya","Result": [
            {
                "symbol": "YHOO","name": "Yahoo! Inc.","exch": "NMS","type": "S","exchDisp": "NASDAQ"

            }
        ]
    }
}
)

我想获得Result 1st数组数据

我正在尝试使用下面但它不适合我

$file = "http://d.yimg.com/autoc.finance.yahoo.com/autoc?query=yahoo&callback=YAHOO.Finance.SymbolSuggest.ssCallback";
$data = file_get_contents($file);
$result = json_decode($data);

我想得到第一个数组符号的结果

我用了

$result [‘YAHOO.Finance.SymbolSuggest.ssCallback’] [‘ResultSet’] [‘result’] [‘symbol’]

它没有工作,请帮助我,我如何从上面的API获得符号

谢谢

解决方法

试试这个

<?php
$file = "http://d.yimg.com/autoc.finance.yahoo.com/autoc?query=yahoo&callback=YAHOO.Finance.SymbolSuggest.ssCallback";
$data = file_get_contents($file);
$data = mb_substr($data,strpos($data,'{'));
$data = mb_substr($data,-1);
$result = json_decode($data,true);
print_r($result['ResultSet']['Result'][0]);
