在PHP中提取JSONP结果集

我想能够得到这个url返回的数据。 我甚至可以用PHP做这个吗

    <?php
    $yahooSS = "http://d.yimg.com/autoc.finance.yahoo.com/autoc?query=yahoo&callback=YAHOO.Finance.SymbolSuggest.ssCallback";

    $yss = fopen($yahooSS,"r");
    ....

非常感谢您提供的任何帮助。

对，您必须删除函数名（和括号），然后才能使用语法解析JSON

我曾经为此编写过一个函数：

function jsonp_decode($jsonp, $assoc = false) { // PHP 5.3 adds depth as third parameter to json_decode
    if($jsonp[0] !== '[' && $jsonp[0] !== '{') { // we have JSONP
       $jsonp = substr($jsonp, strpos($jsonp, '('));
    }
    return json_decode(trim($jsonp,'();'), $assoc);
}

用法：

$data = jsonp_decode($response);

首先尝试一下，它可能会为您省去麻烦：只需从URL中省略

回调

参数

如果定义了

callback

，则此Web服务具有相当标准的生成JSONP的行为；普通JSON则不然。试试看：

返回纯JSON:

{"ResultSet":{"Query":"yahoo","Result":[{"symbol":"YHO.HM","name":"YAHOO","exch":"HAM","type":"S","exchDisp":"Hamburg","typeDisp":"Equity"},{"symbol":"YHOO","name":"Yahoo! Inc.","exch":"NAS","type":"S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"YAHOY","name":"Yahoo Japan Corporation","exch":"PNK","type":"S","exchDisp":"OTC Markets","typeDisp":"Equity"},{"symbol":"YHOO.MX","name":"Yahoo!

返回JSONP（包装在函数调用中的JSON）：
