我正在尝试单独打印API调用的结果。我正在调用YQL API调用。
这是我使用的PHP脚本
<?php
if (!$_REQUEST["q"]) return;
$query = $_REQUEST["q"];
$q = "'http://google.com/complete/search?output=toolbar&q=$query'";
$query = "select * from xml where url=$q";
$url = "http://query.yahooapis.com/v1/public/yql?q=";
$url .= rawurlencode($query);
$url .= "&format=json&env=store://datatables.org/alltableswithkeys";
function get_data($url) {
$ch = curl_init();
$timeout = 5;
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$data = get_data($url);
// decode the data and get the first result set.
$info = json_decode($data);
foreach( $info['suggestion']['data'] as $i ) {
echo $i;
}
?>
我从API调用中得到的结果是
cbfunc({

我正在尝试迭代建议对象，并尝试打印建议对象的数据属性。
我得到以下错误：
Fatal error: Cannot use object of type stdClass as array
这可能会解决您的问题：
foreach( $info['query']['results']['toplevel']['CompleteSuggestion'] as $i ) {
echo $i['suggestion']['data'];
echo "<br>";
}
好吧，它正在返回由javascript回调函数cbfunc(JSON_RESPONSE_DATA);包装的数据。。。。您可以从开始删除cbfunc(，从结束删除);，并执行print_r(json_decode(REST_OF_THE_RESPONSE, true));。。。瞧！。。。你得到了数组。。。
希望这能有所帮助。
要数组输出，您需要将true参数作为第二个参数。否则它将返回对象。请参阅：json_decode
// decode the data and get the first result set.
$info = json_decode($data, true);
//var_dump($info);
foreach( $info['suggestion']['data'] as $i ) {
echo $i;
}
尝试使用json_decode($data, true);。请参阅手册：json_encode（）。
第二个参数当为TRUE时，返回的对象将被转换为关联数组。
