The example in this article describes the PHP web page virus removal class. Share it with everyone for your reference. The details are as follows:

I believe that many people’s web pages are often added with some Trojan addresses in the background of php, asp, html, js and other files for no reason, causing a lot of trouble! I used to have a website like this, so I wrote this code out of anger. Although the article is a bit of a waste of resources, it is still better than cleaning it manually. Now I will talk about the principle of virus removal through the program.

First we need to read the $checkFile file. This article is to determine whether an article is infected. If so, all files in the txt file path in the $savafile variable will be executed and cleared according to your infecFile virus list.

Copy code The code is as follows:

Class clear_virus{
//public $content;
public $infectFile ='virus.txt';//Virus file list file
public $savefile ="save.txt";//List of files to view viruses
public $timep ='time.txt'; //Some records of virus removal time
public $checkFile ='e.php';//Here are the settings
public $run =0;
public $virus_type;
public $replace ;
public $filepath ;
public $tag =0;
 
function open_file(){
$this->read_virus();
$this->check_File();
if($this->run){
$this->update_time();
$this->read_file() ;
foreach($this->filepath as $tmppath){
If(file_exists($tmppath)){
$tmp_file =file_get_contents($tmppath);
            print_r( $this->virus_type);                                           for( $i=0;$ivirus_type);$i++ ){
If( strrpos($tmp_file,$this->virus_type[$i])!== false){
              $tmp_file =str_replace($this->virus_type[$i],'',$tmp_file);
              $this->tag =1;                                                                                                                                                     }
If( $this->tag ){
            $handle =fopen($tmppath,'w');
              fwrite($handle,$tmp_file);
             fclose($handle);
            unset($tmp_file);                                                                                                        
}else{
; ;
                                                              }  
}
}

function check_File(){
if(file_exists($this->checkFile) ){
$temp =file_get_contents($this->checkFile) ;
echo $temp;
foreach( $this->virus_type as $v_tmp ){
If( strrpos($temp,$v_tmp)!== false ){
$this->run =1;
        break;
        }
}  
echo $this->run;
                                                                                                                                                                                            unset($temp);               }else{
$this->show_error(5);
}
}

function update_time(){
if(file_exists($this->timep) ){
$tmp_time =date("Y-m-d H:i:s").chr(13).'|';
$tmp_fp =fopen($this->timep,'a+');
fwrite($tmp_fp,$tmp_time);
fclose($tmp_fp);
}
 
}


function read_File(){
if(file_exists($this->savefile) ){
$this->content =file($this->savefile);
if(is_array($this->content)){
$this->filepath =$this->content;
}else{
$this->show_error(3);
}
}else{
$this->show_error(4);
}  
}


function read_virus(){
if(file_exists($this->infectFile) ){
$this->replace =file($this->infectFile);
if(is_array($this->replace)){
$this->virus_type=$this->replace; $this->virus_type=$this->replace;
}else{
$this->show_error(1);
}
}else{
$this->show_error(2);
}  
}


function show_error($number){
$array = array(
'1'=>'The virus file cannot be read!',
'2'=>'The virus file list does not exist!',
'3'=>'The file list is no longer saved',
'4'=>'The scanned files are not saved',
'5'=>$this->$checkFile.'Does not exist, please set the virus infection file'
);
echo $array[$number];
}
     
}
$virus =new clear_virus;
$virus->open_file();
?>
