retrieve google image search using foreach - image

Question

I used the following function to get google search images
function get_images($query){
$url = 'http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=';
$url .= urlencode($query);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($curl);
curl_close($curl);
//decoding request
$result = json_decode($data, true);
return $result;
}
It works good when I output all results using print_r()
$images = get_images("porsche");
print_r($images);
But when I want to get a specific value using foreach()
foreach ($images->responseData->results as $result) {
echo $result->url;
}
I got an error:
Notice: Trying to get property of non-object
How can I get any specific value separetly using foreach()?

Try this :
<?php
function get_images($query){
$url = 'http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=';
$url .= urlencode($query);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($curl);
curl_close($curl);
//decoding request
$result = json_decode($data, true);
return $result;
}
$images = get_images("porsche");
//print_r($images);
foreach ($images['responseData']['results'] as $result) {
echo $result['url']. "<br>";
}
?>
