Accéder aux propriétés de l'objet? API Google

Question

<?PHP 

$ip = $_SERVER['REMOTE_ADDR']; 
$searchterm = str_replace(' ', '%20', $_POST["searchterm"]); 


if(isset($_POST["submit"])){ 
// The request also includes the userip parameter which provides the end 
// user's IP address. Doing so will help distinguish this legitimate 
// server-side traffic from traffic which doesn't come from an end-user. 
$url = "https://ajax.googleapis.com/ajax/services/search/web?v=1.0&" 
    . "q=".$searchterm."&userip=".$ip; 

// sendRequest 
// note how referer is set manually 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_REFERER, bla.myserver.net); 
$body = curl_exec($ch); 
curl_close($ch); 

// now, process the JSON string 
$json = json_decode($body); 
// now have some fun with the results... 
} 

?> 

<form method="POST" action="<?PHP $_SERVER["PHP_SELF"]; ?>"> 
<p><input type="text" name="searchterm"></p> 
<p><input type="submit" name="submit"></p> 
</form> 

<?PHP 

if(isset($_POST["submit"])){ 

print_r($json); 


$jsonNew = $json->{'results'}; 
print_r($jsonNew); 
} 

?> 

La sortie pour la variable $ json est

Je veux accéder à une propriété d'un objet, mais cela ne fonctionne pas:

$jsonNew = $json->{'results'}; 
print_r($jsonNew); 

Et par la façon dont il doesn ne lancez pas d'erreur ou d'avertissement. Cela ne montre rien. Des idées?

Je l'ai recherché sur Google, mais je ne trouve pas d'informations supplémentaires sur l'API de recherche Google et sur l'utilisation du résultat de la requête de recherche.

Answer 1

Vous pouvez accéder à l'élément requis en tant que $ json-> responseData-> results [$ x]. où $ x est le numéro de l'élément.

Ou vous pouvez aussi tout simplement par boucle la chose entière comme

for($x=0;$x<count($json->responseData->results);$x++){ 

    echo "</br>URL: "; 
    echo $json->responseData->results[$x]->url; 
    echo "</br>VisibleURL: "; 
    echo $json->responseData->results[$x]->visibleUrl; 
    echo "</br>Title: "; 
    echo $json->responseData->results[$x]->title; 
    echo "</br>Content: "; 
    echo $json->responseData->results[$x]->content; 
    echo "</br>"; 

}
