Homephp教程php手册取得页面所有不重复连接的函数

函数|页面|重复

  由于需要我做了个函数,实现取得页面连接放到数组
  思路:1,取得静态+不带参数的:
  htm html asp php jsp cgi
  a,包含绝对路径的处理:直接取得
  preg_match_all ()?
  b,包含相对路径的,路径得到处理参数:
  根据情况(. 或 .. )处理得到绝对路径
  2,取得带参数的:
  3,经过筛选:选择了一些可以读的后缀比如asp,php,html等
  连接重复的进行删除。
  4,直接运行代码就把 落伍者论坛 » 网站建设专栏
  第一页面的连接拿下来到数组$e中,$e[o][0]为第一个连接;$e[o][1]为第2个
  
  
Code:

  $e=clinchgeturl("http://im286.com/forumdisplay.php?fid=1");
  
  var_dump($e);
  function clinchgeturl($url)
  {
  
  //$url="http://127.0.0.1/1.htm";
  //$rootpath="http://fsrootpathfsfsf/yyyyyy/";
  //var_dump($rrr);
  if(eregi('(.)*[\.](.)*',$url)){
   $roopath=split("\/",$url);
   $rootpath="http://".$roopath[2]."/";
   $nnn=count($roopath)-1;for($yu=3;$yu   // var_dump($rootpath); //http: ,'',127.0.0.1,xnml,index.php
   }
   else{$rootpath=$url;//var_dump($rootpath);
  }
  if(isset($url)){
  echo "$url 有下列裢接:

  $fcontents = file($url);
