直接上代码，免的自己忘记了

<?php
echo "Hello World!";
$url = "http://www.youdao.com/w/ok/#keyfrom=dict2.top";//要爬取的网址
//$url = "https://www.runoob.com/html/html-links.html";//要爬取的网址
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt ($ch,  CURLOPT_HEADER,false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
	//设置用户代理(后缀为.top的网址不加这个获取不到内容。)
	curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.172 Safari/537.22");

	//关闭直接输出
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	//加入重定向处理
	curl_setopt($ch, CURLOPT_FOLLOWLOCATION ,1); 
    $response = curl_exec($ch);	
	
	echo curl_errno($ch);	
	
	echo($response);
	curl_close($ch);
?>

先获取到了全部内容，在弄指定的内容。好像要用正则表达式，这个也是十窍通了九窍，一窍不通…
