如何遍历此数组并在每行中打印一个结果。这是由谷歌搜索API返回的。
这对我有用
print_r($rez->responseData);
但这不是
print_r($rez->responseData->results); nor this print_r($rez->responseData['results']);
下面是数组
stdClass Object

这是生成此内容的代码。
<?php
/**
* google_search_api()
* Query Google AJAX Search API
*
* @param array $args URL arguments. For most endpoints only "q" (query) is required.
* @param string $referer Referer to use in the HTTP header (must be valid).
* @param string $endpoint API endpoint. Defaults to 'web' (web search).
* @return object or NULL on failure
*/
function google_search_api($args, $referer = 'http://localhost/test/', $endpoint = 'web'){
$url = "http://ajax.googleapis.com/ajax/services/search/".$endpoint;
if ( !array_key_exists('v', $args) )
$args['v'] = '1.0';
$url .= '?'.http_build_query($args, '', '&');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// note that the referer *must* be set
curl_setopt($ch, CURLOPT_REFERER, $referer);
$body = curl_exec($ch);
curl_close($ch);
//decode and return the response
return json_decode($body);
}
print_r($rez->responseData);
答案 0 :(得分：2)
类似的东西：
$obj = new obj(); // your object
function printLies($obj)
{
foreach ($obj as $elem)
{
if (is_array($elem) || is_object($elem))
{
printLies($obj);
}
else
{
echo $elem . '<br />';
}
}
}
或者我不明白这个问题？也许你的意思是这个？
$obj = new obj(); // your object
foreach ($obj->result as $result)
{
print_r($result);
}
