使用 PHP 以 HTML 格式返回 Google 图片搜索结果 [英] Return Google Image Search Results in HTML using PHP

问题描述

我知道如何使用 Google API 在 AJAX 中返回图像结果，但我希望能够为特定查询返回图像，然后将它们输出到我页面上的 HTML 中.

I know how we can use the Google API to return image results in AJAX, but I want to be able to return images for a specific query and then output them in to HTML on my page.

例如:

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

返回带有关键字 sausages 前 10 个结果的信息和图像的结果.

Returns results with infomation and images about the top 10 results for the keyword sausages.

如何在 HTML 中使用 PHP 查询此 url 以输出我页面上图像的图像和标题.

How can I query this url to output the images and titles of the images on my page using PHP in HTML.

我在函数顶部使用以下内容返回标题:

I am using the following at the top of the function to return the title:

$tit = get_the_title();

然后我在这里附加它:

$json = get_url_contents('http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q='.$tit.'');

但它不会识别标题

推荐答案

function get_url_contents($url) {
    $crl = curl_init();

    curl_setopt($crl, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)');
    curl_setopt($crl, CURLOPT_URL, $url);
    curl_setopt($crl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($crl, CURLOPT_CONNECTTIMEOUT, 5);

    $ret = curl_exec($crl);
    curl_close($crl);
    return $ret;
}

$json = get_url_contents('http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=sausages');

$data = json_decode($json);

foreach ($data->responseData->results as $result) {
    $results[] = array('url' => $result->url, 'alt' => $result->title);
}

print_r($results);

输出:

Array
(
    [0] => Array
        (
            [url] => http://upload.wikimedia.org/wikipedia/commons/thumb/c/c4/Salchicha_oaxaque%25C3%25B1a.png/220px-Salchicha_oaxaque%25C3%25B1a.png
            [alt] => Sausage - Wikipedia, the free encyclopedia
        )

    [1] => Array
        (
            [url] => http://upload.wikimedia.org/wikipedia/commons/c/c1/Reunion_sausages_dsc07796.jpg

        )

    [2] => Array
        (
            [url] => http://1.bp.blogspot.com/-zDyoLPoM1Zg/ULXDPba_2iI/AAAAAAAAAAs/QzfNNmDFmzc/s1600/shop_sausages.jpg
            [alt] => Maik's Yummy German Sausage
        )

    [3] => Array
        (
            [url] => http://sparseuropeansausage.com/images/sausage-web/sausagesBiggrilling2.jpg
            [alt] => Spar's European Sausage Shop
        )

)

显示图像:

<?php foreach($results as $image): ?>
    <img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>"/><br/>
<?php endforeach; ?>

<小时>

评论后

$url = 'http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=' . get_the_title(); 

$json = get_url_contents($url);
