本文实例讲述了PHP实现批量删除挂马文件及批量替换页面内容的方法。分享给大家供大家参考，具体如下：
PHP;">
read())) {
if($v == "." || $v == "..") continue;
$file = $d->path."/".$v;
if(is_dir($file)) {
echo "$file ";
$body = file_get_contents($file);
if($isreg == 1){
$body2 = preg_replace($sstr,$body);
}else{
$body2 = str_replace($sstr,$body);
}
if($body != $body2 && $body2 != ''){
tofile($file,$body2);
echo ' OK';
}else{
echo ' NO';
}
echo ' ';
}
}
}
$d->close();
}
function hx_dealdir($dir){
global $sstr,$arrext;
if ($dh = opendir($dir)) {
while (false !== ($file = readdir($dh))) {
if(filetype($dir.'/'.$file)=='file'){
$ext=substr(strrchr($file,$arrext) ){
echo "$file ";
$body = file_get_contents($dir.'/'.$file);
if($isreg == 1){
$body2 = preg_replace($sstr,$body);
}
if($body != $body2 && $body2 != ''){
tofile($dir.'/'.$file,$body2);
echo ' OK';
}else{
echo ' NO';
}
echo ' ';
}
}
}
closedir($dh);
}
}
//把生成文件的过程写出函数
function tofile($file_name,$file_content){
if (is_file ($file_name)){
@unlink ($file_name);
}
$handle = fopen ($file_name,"w");
if (!is_writable ($file_name)){
return false;
}
if (!fwrite ($handle,$file_content)){
return false;
}
fclose ($handle); //关闭指针
return $file_name;
}
?>
