使用SimpleHTMLDom獲得大圖片THROU谷歌搜索

Question

我需要證明被搜查由谷歌THROU simple_html_dom.php

include_once("simple_html_dom.php"); 
     $key="alexis"; 
     $html = new simple_html_dom(); 
     $html=file_get_html('http://images.google.com/images?as_q='. $key .'&hl=en&imgtbs=z&btnG=Search+Images&as_epq=&as_oq=&as_eq=&imgtype=&imgsz=m&imgw=&imgh=&imgar=&as_filetype=&imgc=&as_sitesearch=&as_rights=&safe=images&as_st=y'); 
foreach($html->find('a') as $element) { 
preg_match('#(?:http://)?(http(s?)://([^\s]*)\.(jpg|gif|png))#', $element->href, $imagelink); 
echo $imagelink['1']; 
} 

結果有多大的圖像：

Answer 1

include_once("simple_html_dom.php"); 
     $key="alexis"; 
     $html = new simple_html_dom(); 
     $html=file_get_html('http://images.google.com/images?as_q='. $key .'&hl=en&imgtbs=z&btnG=Search+Images&as_epq=&as_oq=&as_eq=&imgtype=&imgsz=m&imgw=&imgh=&imgar=&as_filetype=&imgc=&as_sitesearch=&as_rights=&safe=images&as_st=y'); 
foreach($html->find('a') as $element) { 
if(preg_match('#(?:http://)?(http(s?)://([^\s]*)\.(jpg|gif|png))#', $element->href, $imagelink)){ 
    echo $imagelink[1]; 
    break; 
} 
} 

Answer 2

add a break;後與echo行：

... 
echo $imagelink['1']; 
break; 
}
