使用Google API进行域索引检查

Question

I am trying to build website where a user can enter his website and check his indexed pages in google. Just like we do by site:domain.com

I am using a google API, here is the link to API (I know it's deprecated)

http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=

when I use a code like

<?php  

function getGoogleCount($domain) {
    $content = file_get_contents('http://ajax.googleapis.com/ajax/services/' .
        'search/web?v=1.0&filter=0&q=site:' . urlencode($domain));
    $data = json_decode($content);
    return ($data->responseData->cursor->estimatedResultCount);
}

echo getGoogleCount('stackoverflow.com');

?>

good as far as I want to know about the result counts But the next thing I want is to list all the results on my website. I am unable to grab the results because when we write

$data->responseData->cursor->estimatedResultCount

It goes straight But when we try to get results. I don't know how to do, just to print the idea

$data->responseData->results->[url & title & content here]

Because here results is an array. and I don't know how can I store info in an array in this case.

Have been searching for a long time but can't find anything related.....

Thanks in advance...

The easiest way is to use:

$data = json_decode($content, true);

That will convert objects to normal associative arrays which are probably easier to handle. Then you access your values by something like this:

$results = $data['responseData']['results']; //array
$googleCount = $data['responseData']['cursor']['estimatedResultCount'];

Then with the results you can do something like this:

foreach ($results as $result) {
    echo $result['title'].' -> '.$result['url'] . '<br />';
}

But of course if you don't like associative arrays and you prefer objects, you could do it also this way:

$data = json_decode($content);
foreach ($data->responseData->results as $result) {
    echo $result->title .' -> '.$result->url.'<br />';
}

If you want to check which properties has the $result, just use print_r or var_dump.
