返回谷歌图片搜索结果中的HTML使用PHP [英] Return Google Image Search Results in HTML using PHP

问题描述

我知道我们如何利用谷歌API在AJAX返回的图像效果，但我希望能够到我的网页上为特定的查询返回的图像，然后将它们输出到HTML。

例如：

<一个href=\"http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=sausages\">http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=sausages

返回的结果与前10个结果关键字香肠信息来源和图像。

我怎样可以查询这个网址来输出图像的图片和标题在HTML中使用PHP我的网页上。

我使用的函数的顶部下面，返回标题

  $针锋相对= get_the_title（）;
 

然后我在这里apending是：

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

但它不会承认标题

解决方案

 函数get_url_contents（$网址）{
    $ CRL = curl_init（）;    curl_setopt（$ CRL，CURLOPT_USERAGENT，Mozilla的/ 4.0（兼容; MSIE 6.0; Windows NT的5.1; .NET CLR 1.1.4322）'）;
    curl_setopt（$ CRL，CURLOPT_URL，$网址）;
    curl_setopt（$ CRL，CURLOPT_RETURNTRANSFER，1）;
    curl_setopt（$ CRL，CURLOPT_CONNECTTIMEOUT，5）;    $ RET = curl_exec（$ CRL）;
    curl_close（$ CRL）;
    返回$ RET;
}$ JSON = get_url_contents（'http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=sausages'）;$数据= json_de code（$ JSON）;的foreach（$数据 - ＆GT; responseData-＆GT;结果$结果）{
    $结果[] =阵列（'URL'=＆GT; $ result-＆GT; URL，ALT =＆GT; $ result-＆GT;标题）;
}的print_r（$结果）;
 

输出：

显示图像：

＆LT; PHP endforeach; ？＆GT;

的意见后，编辑：

  $ URL ='http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=。 get_the_title（）;$ JSON = get_url_contents（$网址）;
 

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.

For example:

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

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

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

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

$tit = get_the_title();

Then I am apending it here:

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

But it won't recognize the title

解决方案

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);

Output:

Array
(
    [0] => Array
        (
            [url] => http://upload.wikimedia.org/wikipedia/commons/thumb/c/c4/Salchicha_oaxaque%25C3%25B1a.png/220px-Salchicha_oaxaque%25C3%25B1a.png

        )

    [1] => Array

            [alt] => Spar's European Sausage Shop
        )

)

Showing the images:

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

Edit after comments:

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

$json = get_url_contents($url);
