现在比较狂的网页病毒代码,常常让你的网站饱受网页病毒代码困扰,我公司服务器也碰到同样的问题了,早上烦躁中写了一个清除网页病毒的php程序,原理是每次访问是都会调用这种程序,读取一个index文件是否有毒如果有就把执行程序把病毒替换掉就OK了,只是临时的办法了,希望高手出更高级的方法处理吧.

 Class clear_virus{
  public $index  ='b.html';
  public $filepath =array('b.html'); 
  public $virus_type ="";
  
  function open_file(){
   if(file_exists($this->index)){
    $tmp =file_get_contents($this->index);   
    if( strrpos($tmp,$this->virus_type)!== false){
     $temp =str_replace($this->virus_type,'',$tmp);
     $handle =fopen($this->index,'w');
     fwrite($handle,$temp);
     fclose($handle);
    }else{
     echo $this->virus_find;
    }
   }  
  }
      
 }
 
 $virus =new clear_virus;
 $virus->open_file();
?>
