You could use the PHP Simple HTML DOM libraryfor this:
您可以为此使用PHP Simple HTML DOM 库：
<?php
include "simple_html_dom.php";
$search_query = "ENTER YOUR SEARCH QUERY HERE";
$search_query = urlencode( $search_query );
$html = file_get_html( "https://www.google.com/search?q=$search_query&tbm=isch" );
$image_container = $html->find('div#rcnt', 0);
$images = $image_container->find('img');
$image_count = 10; //Enter the amount of images to be shown
$i = 0;
foreach($images as $image){
if($i == $image_count) break;
$i++;
// DO with the image whatever you want here (the image element is '$image'):
echo $image;
}
This will print a specific number of images (number is set in '$image_count').
这将打印特定数量的图像（数量在 '$image_count' 中设置）。

i am not very much sure about this ,but still google gives a nice documentation about this.
我对此不太确定，但谷歌仍然提供了一个很好的文档。
$url = "https://ajax.googleapis.com/ajax/services/search/images?" .
"v=1.0&q=barack%20obama&userip=INSERT-USER-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, /* Enter the URL of your site here */);
$body = curl_exec($ch);
curl_close($ch);
// now, process the JSON string
$json = json_decode($body);
// now have some fun with the results...
this is from the official Google's developer guide regarding image searching. for more reference you can have a reference of the same here.
这是来自官方谷歌关于图像搜索的开发人员指南。如需更多参考，您可以在此处获得相同的参考。

in $url you must set the search keywords.
在 $url 中，您必须设置搜索关键字。
