什么是curl
curl是利用URL语法在命令行方式下工作的开源文件传输工具。
PHP 的用处
使用PHP的cURL库可以简单和有效地去抓网页。你只需要运行一个脚本，然后分析一下你所抓取的网页，然后就可以以程序的方式得到你想要的数据了。无论是你想从从一个链接上取部分数据，或是取一个XML

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>$ch</span>);<span>?></span></span></code>
demo2 post数据
<code>﹤?php<span>$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>$ch</span>);?﹥</code>
demo3 使用代理服务器
<code>﹤?php <span>$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>);?﹥</code>
‘).addClass(‘pre-numbering’).hide(); $(this).addClass(‘has-numbering’).parent().append($numbering); for (i = 1; i <= lines; i++) { $numbering.append($('
‘).text(i)); }; $numbering.fadeIn(1700); }); }); </script>以上就介绍了PHP curl，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
