Question

所以我遇到以下代码的问题。

我已将CURLOPT_RETURNTRANSFER设置为true，但在curl_exec被点击时未返回任何内容。任何和所有的帮助表示赞赏！

<?php

    $yql_base_url = "http://query.yahooapis.com/v1/public/yql?q=";  
    $yql_query = "select * from csv where url='http://download.finance.yahoo.com/d/quotes.csv?s=YHOO,GOOG,AAPL&f=sl1d1t1c1ohgv&e=.csv' and columns='symbol,price,date,time,change,col1,high,low,col2'"; 
    $yql_params = "&format=json&diagnostics=true&callback=";

    $yql_url = $yql_base_url . urlencode($yql_query) . $yql_params;  

    $session = curl_init($yql_url);
    curl_setopt($session, CURLOPT_RETURNTRANSFER, true);

    $json = curl_exec($session);
    curl_close($session);

    $phpObj = json_decode($json);

    if(!is_null($phpObj->query->results))
    {  
        echo $phpObj->query->results;
    }  

?>

Answer 1

$phpObj->query->results是一个Object数组，您无法对其进行echo。只需在其上使用print_r()或var_dump()。

示例：

print_r($phpObj->query->results);
var_dump($phpObj->query->results);

无法加载php curl结果
