　　参考别人想法变成自己的想法，你会发现慢慢下来以后你就拥有了临时解决很多问题的思路与方法。
复制代码 代码如下:
<?php
/*
功能:获取页面内容,存储下来阅读; lost63
*/
Class GetUrl{
var $url; //地址
var $result; //结果
var $content; //内容
var $list; //列表
function GetUrl($url){
$this->url=$url;
$this->GetContent();
$this->GetList();
$this->FileSave();
//print_r($this->list[2]);
}
private function GetContent(){
$this->result=fopen($this->url,r);
while(!feof($this->result)){
$this->content.=fgets($this->result,9999);
}
}
private function GetList(){
preg_match_all(/<a(.*?)href=(.*?)>(.*?)<\/a>/,$this->content,$this->list);
$this->list[2]=array_unique($this->list[2]); //移除相同的值
while(list($key,$value)=each($this->list[2])){
if(strpos($value,.html)==0strpos($value,jiaocheng)==0){
unset($this->list[2][$key]);
}else{
$this->list[2][$key]=substr($value,0,strpos($value,.html))..html; //去掉不需要的标签
}
}
}
private function FileSave(){
foreach($this->list[2] as $value){
$this->url=$value; //重新赋值
$this->content=null;
$this->GetContent(); //提取内容
preg_match_all(/<title>(.*?)<\/title>/,$this->content,$files); //取标题
$filename=$files[1][0]..html; //存储名
$content=$this->str_cut($this->content,
$file=fopen($filename,w);
fwrite($file,$content);
fclose($file);
echo $filename.保存 OK<br>\n;
}
}
function str_cut($str ,$start, $end) {
$content = strstr( $str, $start );
$content = substr( $content, strlen( $start ), strpos( $content, $end ) - strlen( $start ) );
return $content;
}
}
$w=new GetUrl(
?>
