好吧，我想你想在网页内搜索非常像cntrl + f提供。所以这可以通过使用java脚本完成。对于演示，生成一个html文件，粘贴下面的代码并检查它将如何工作。

<html> 
    <head> 
    </head> 
    <body> 
    my name is amit yadav, type amit to search 
    <script>

     var dupeRange = null; 
     var TestRange = null; 
     var win = null; 
     var nom = navigator.appName.toLowerCase(); 
     var agt = navigator.userAgent.toLowerCase(); 
     var is_major = parseInt(navigator.appVersion); 
     var is_minor = parseFloat(navigator.appVersion); 
     var is_ie  = (agt.indexOf("msie") != -1); 
     var is_ie4up = (is_ie && (is_major >= 4)); 
     var is_not_moz = (agt.indexOf('netscape')!=-1) 
     var is_nav  = (nom.indexOf('netscape')!=-1); 
     var is_nav4 = (is_nav && (is_major == 4)); 
     var is_mac  = (agt.indexOf("mac")!=-1); 
     var is_gecko = (agt.indexOf('gecko') != -1); 
     var is_opera = (agt.indexOf("opera") != -1); 


     // GECKO REVISION 

     var is_rev=0 
     if (is_gecko) { 
      temp = agt.split("rv:")

看到你的答案很好..我可以知道如何使用mysql吗？谢谢 – pcs 2015-05-20 10:11:35

你可以在想要搜索的字段上使用'like'运算符 – 2015-06-11 07:51:33

您需要用自己的索引（MySQL的），你自己的爬虫（这也许应该还是指数的结果），或者你可以从谷歌受益：

不，我不想使用谷歌。 – Someone 2012-01-09 07:53:01

好吧，我会提醒你重新考虑，因为你想在这里重新发明轮子，但是你可以看看unix grep命令 – landons 2012-01-09 07:55:45

最快，最简单，最脏的方法是使用php EXEC命令和GREP。它不是一个好主意，虽然（可怕的安全性）。

更好的方法是使用预先构建的搜索缓存。 Zend framework有一个search module，很容易使用。

使用cURL下载网页，然后将其放入一个文本文件。从那里使用本机功能找到你正在寻找的东西:)

如果文件是物理上存在于服务器上，你可以使用像file_get_contents（实际上与mySQL无关）的函数。

如果要抓取网站的内容，可以使用cURL或HttpRequest。
