网页病毒清除办法
你的网页是不是经常被无故的在php,asp,html,js 等文件后台加上一些木马地址呢?我以前有个站就是这样,所以一恨之下写了这段代码,文章虽然有一点浪费资源了,但是总比我们手动清除要好吧,下面我为讲讲程序的清除病毒的原理吧.
首先们要读取 $checkFile 文件这个文章是判断一个文章 是否被感染了,如果是就会执行$savafile变量里面的txt文件路径的所有文件,进行按你infecFile病毒列表清除一次.
Class clear_virus{
//public $content;
public $infectFile ='virus.txt';//病毒文件列表文件
public $savefile ="save.txt";//所在查看病毒的文件列表
public $timep ='time.txt';//些记录清除病毒时间
public $checkFile ='e.php';//这里是设置
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( $i=0;$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;
}else{
$this->show_error(1);
}
}else{
$this->show_error(2);
}
}
function show_error($number){
$array = array(
'1'=>'病毒文件未不能读取!',
'2'=>'病毒文件列表不存在!',
'3'=>'文件列表不存了',
'4'=>'查杀的文件不存',
'5'=>$this->$checkFile.'不存在了,请设置病毒感染文件'
);
echo $array[$number];
}
}
$virus =new clear_virus;
$virus->open_file();
?>

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

HTML defines the web structure, CSS is responsible for style and layout, and JavaScript gives dynamic interaction. The three perform their duties in web development and jointly build a colorful website.

React combines JSX and HTML to improve user experience. 1) JSX embeds HTML to make development more intuitive. 2) The virtual DOM mechanism optimizes performance and reduces DOM operations. 3) Component-based management UI to improve maintainability. 4) State management and event processing enhance interactivity.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
