php读取html并截取字符串的简单代码

前端之家收集整理的这篇文章主要介绍了php读取html并截取字符串的简单代码前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

代码如下:
PHP
$title='编程之家';
$hello='jb51.cc!';
$file=file_get_contents('http://www.baidu.com');
$file=iconv("gbk//IGNORE","utf-8",$file);
//echo $file;
echo strpos($file,''); <BR>echo substr($file,strpos($file,'<title>')+7,''-strpos($file,'')+7)); <BR>$file=str_replace(array('<a href="https://www.jb51.cc/tag/baidu/" target="_blank" class="keywords">百度</a>一下','{hello}'),array($title,$hello),$file); <BR>?> <BR></div><BR>下面是渝海用的小偷程序<a href="https://www.jb51.cc/tag/daima/" target="_blank" class="keywords">代码</a>。大家可以多看下。编程之家提供多款小偷程序。<BR><div class="codetitle"><span><a style="CURSOR: pointer" data="14502" class="copybut" id="copybut14502" onclick="doCopy('code14502')"><U></U></a> <a href="https://www.jb51.cc/tag/daima/" target="_blank" class="keywords">代码</a>如下:</div><div class="codebody" id="code14<a href="https://www.jb51.cc/tag/502/" target="_blank" class="keywords">502</a>"><BR><?<a href="https://www.jb51.cc/tag/PHP/" target="_blank" class="keywords">PHP</a> <BR>function _url($Date){ <BR>$ch = curl_init(); <BR>$timeout = 5; <BR>curl_setopt ($ch,CURLOPT_URL,"$Date"); <BR>curl_setopt ($ch,CURLOPT_RETURNTRANSFER,1); <BR>curl_setopt ($ch,CURLOPT_USERAGENT,"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)"); <BR>curl_setopt ($ch,CURLOPT_CONNECTTIMEOUT,$timeout); <BR>$contents = curl_exec($ch); <BR>curl_close($ch); <BR>return $contents; <BR>} <BR>$url="//www.jb51.cc"; <BR>$contents.=_url($url); <BR>echo $contents; //<a href="https://www.jb51.cc/tag/shuchu/" target="_blank" class="keywords">输出</a><a href="https://www.jb51.cc/tag/neirong/" target="_blank" class="keywords">内容</a> <BR>?><BR></div></P><i class="glyphicon glyphicon-link"></i> 原文链接:https://www.f2er.com/php/28912.html</div> <div class="topcard-tags"><a href="https://www.f2er.com/tag/phpp/" class="tag_link" target="_blank">php</a><a href="https://www.f2er.com/tag/jiequzifuchuan/" class="tag_link" target="_blank">截取字符串</a></div> <ul class="list-group"> <li class="list-group-item"><a href="https://www.f2er.com/php/28913.html" title="php 获取客户端的真实ip">上一篇:php 获取客户端的真实ip</a><a href="https://www.f2er.com/php/28911.html" title="PHP MYSQL乱码问题,使用SET NAMES utf8校正" class="text-muted pull-right">下一篇:PHP MYSQL乱码问题,使用SET NAMES </a> </li> </ul> </div> </div> </div> <!-- row end --> <div class="row row-sm"> <div class="col-sm-12 col-md-12 col-lg-12"> <div class="card"> <ins class="adsbygoogle" style="display:block" data-ad-format="autorelaxed" data-ad-client="ca-pub-4605373693034661" data-ad-slot="9144498553"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script></div> </div> </div> <div class="row row-sm"> <div class="col-sm-12 col-md-12 col-lg-12"> <div class="card"> <div class="title"><h1>猜你在找的PHP相关文章</h1></div> <div class="list_con"> <a href="https://www.f2er.com/php/997740.html" title="Hessian通讯协议【附PHP源代码】"><img class="lazy" src="https://www.f2er.com/images/np.jpg" data-original="https://www.f2er.com/res/2021/02-22/19/361df348b2385424b031f281e9807f35.png" title="" width="160" height="90" style="float:right;margin-left:30px;display:none;" /><div class="title">Hessian通讯协议【附PHP源代码】</div> <div class="summary">Hessian开源的远程通讯,采用二进制 RPC的协议,基于 HTTP 传输。可以实现PHP调用Java,Pyt...</div> <time class="summary">作者:前端之家 时间:2021-02-22</time> </a> </div> <div class="list_con"> <a href="https://www.f2er.com/php/997739.html" title="初识Mongodb总结"><img class="lazy" src="https://www.f2er.com/images/np.jpg" data-original="https://www.f2er.com/res/2021/02-22/19/b4d39ef6acdce4fc3ef2fe713961a4c2.png" title="" width="160" height="90" style="float:right;margin-left:30px;display:none;" /><div class="title">初识Mongodb总结</div> <div class="summary">初识Mongodb的一些总结,在Mac Os X下真实搭建mongodb环境,以及分享个Mongodb管理工具,学习...</div> <time class="summary">作者:前端之家 时间:2021-02-22</time> </a> </div> <div class="list_con"> <a href="https://www.f2er.com/php/997738.html" title="初识Mongodb之[CURD]-PHP版"><img class="lazy" src="https://www.f2er.com/images/np.jpg" data-original="https://www.f2er.com/res/2021/02-22/19/d009a8111c246e74506457f4b9a3356b.png" title="" width="160" height="90" style="float:right;margin-left:30px;display:none;" /><div class="title">初识Mongodb之[CURD]-PHP版</div> <div class="summary">边看边操作,这样才能记得牢,实践是检验真理的唯一标准.光看不练假把式,光练不看傻把式,边看...</div> <time class="summary">作者:前端之家 时间:2021-02-22</time> </a> </div> <div class="list_con"> <a href="https://www.f2er.com/php/997665.html" title="php学习日志 - echo&print"><img class="lazy" src="https://www.f2er.com/images/np.jpg" data-original="https://www.f2er.com/res/2021/02-21/08/daa4210b68d9838740e9ea77a21307fa.png" title="" width="160" height="90" style="float:right;margin-left:30px;display:none;" /><div class="title">php学习日志 - echo&print</div> <div class="summary">在php中,结果输出一共有两种方式:echo和print,下面将对两种方式做一个比较。 echo与pri...</div> <time class="summary">作者:前端之家 时间:2021-02-21</time> </a> </div> <div class="list_con"> <a href="https://www.f2er.com/php/997664.html" title="The mbstring extension is missing.
