PHP 捲曲

什麼是curl

curl是利用URL語法在命令列方式下工作的開源檔案傳輸工具。

PHP 的用處

使用PHP的cURL函式庫可以簡單有效地去抓網頁。你只需要執行一個腳本，然後分析一下你所抓取的網頁，然後就可以以程式的方式得到你想要的資料了。無論是你想從一個連結上取部分數據，或是取一個XML檔案並把其導入資料庫，那怕就是簡單的獲取網頁內容，cURL 是一個功能強大的PHP庫。

demo1

<code><span><span><?php </span><span>//1.初始化，创建一个新cURL资源 </span><span>$ch</span> = curl_init();
    <span>//2.设置URL和相应的选项</span>
    curl_setopt(<span>$ch</span>, CURLOPT_URL, <span>"http://www.lampbrother.net/"</span>) 
    curl_setopt(<span>$ch</span>, CURLOPT_HEADER, <span>0</span>); 
    <span>//3.抓取URL并把它传递给浏览器 </span><span>$data</span> = curl_exec(<span>$ch</span>); 
    <span>//4.显示获得的数据</span>
    var_dump(<span>$data</span>);
    <span>//5.关闭cURL资源，并且释放系统资源 </span>
    curl_close(<span>$ch</span>);
<span>?></span></span></span></code>

demo2 post資料

<code>﹤?php
<span>$phoneNumber</span>　=　<span>'13812345678'</span>;
<span>$message</span>　=　<span>'This　message　was　generated　by　curl　and　php'</span>;
<span>$curlPost</span>　=　<span>'pNUMBER='</span>　.　urlencode(<span>$phoneNumber</span>)　.　<span>'&MESSAGE='</span>　.　urlencode(<span>$message</span>)　.　<span>'&SUBMIT=Send'</span>;
<span>$ch</span>　=　curl_init();
curl_setopt(<span>$ch</span>,　CURLOPT_URL,　<span>'http://www.lxvoip.com/sendSMS.php'</span>);
curl_setopt(<span>$ch</span>,　CURLOPT_HEADER,　<span>1</span>);
curl_setopt(<span>$ch</span>,　CURLOPT_RETURNTRANSFER,　<span>1</span>);
curl_setopt(<span>$ch</span>,　CURLOPT_POST,　<span>1</span>);
curl_setopt(<span>$ch</span>,　CURLOPT_POSTFIELDS,　<span>$curlPost</span>);
<span>$data</span>　=　curl_<span>exec</span>();
curl_close(<span>$ch</span>);

demo3 使用代理伺服器

<code>﹤?php　
<span>$ch</span>　=　curl_init();
curl_setopt(<span>$ch</span>,　CURLOPT_URL,　<span>'http://www.cmx8.cn'</span>);
curl_setopt(<span>$ch</span>,　CURLOPT_HEADER,　<span>1</span>);
curl_setopt(<span>$ch</span>,　CURLOPT_RETURNTRANSFER,　<span>1</span>);
curl_setopt(<span>$ch</span>,　CURLOPT_HTTPPROXYTUNNEL,　<span>1</span>);
curl_setopt(<span>$ch</span>,　CURLOPT_PROXY,　<span>'proxy.lxvoip.com:1080'</span>);
curl_setopt(<span>$ch</span>,　CURLOPT_PROXYUSERPWD,　<span>'user:password'</span>);
<span>$data</span>　=　curl_<span>exec</span>();
curl_close(<span>$ch</span>);
