遍历目录更改文件内容

Question

状况描述：
        我的一个网站被攻击，每个html页面都有恶意js代码
解决目标：
        手工去删除每个页面的恶意代码太费时，现在我想通过程序去遍历网站的目录及文件，遇到.html、.htm、.js类型的文件时打开并删除里面的代码
我在网上找的一个遍历文件的代码：这段代码可以遍历文件，但是没记住路径，导致我要改文件时不知道怎么打开文件，请各位帮帮忙，我PHP并不熟，只会最基础最基础的。<?php
function tree($directory) 
{ 
$mydir=dir($directory); 
echo "<ul>\n"; 
while($file=$mydir->read()){ 
if((is_dir("$directory/$file")) AND ($file!=".") AND ($file!="..")) 
{echo "<li><font color=\"#ff00cc\"><b>$file</b></font></li>\n"; 
tree("$directory/$file"); 
} 
else{
    $a = explode('.',$file);
    if($a[1] == 'html' || $a[1] == 'htm')
   {
        //修改文件的代码，待写
            echo "<li>$file</li>\n"; 
        }    
} 
}
echo "</ul>\n"; 
$mydir->close(); 
} 
//开始运行echo "<h2>目录为粉红色</h2><br>\n"; 
tree("./"); 
?>

<?php
class listDirClass {
    var $dirPath;
    function openDir($dirPath) {
        $this->dirPath = $dirPath;
        if (is_dir($dirPath)) {
            $dir = opendir($dirPath);
            return $dir;
        }else {
            die("$dirPath is Not a Directory");
        }
    }
    function closeDir($dir) {
        closedir($dir);
    }
    function listDir($dir) {
        echo '<ol>';
        while($file = @readdir($dir)) {
            if($file!='.' && $file!='..') { // filter . and ..
                $dd  = $this->dirPath;  //
                $dd  = $dd.'/'.$file;
                echo "<li>$file</li>";
            }
            if(is_dir($dd) && $file!='.' && $file!='..') { // is_dir 参数需要完整的路径
                $subDir = $this->openDir($dd);
                $this->listDir($subDir);
                $this->closeDir($subDir);
            }
        }
        echo '</ol>';
        return true;
    }
}$dirOpt = new listDirClass();
$dirOpt->dirPath = 'D:\minzheng\DBUnity\obj';
$dir = $dirOpt->openDir($dirOpt->dirPath);
$dirOpt->listDir($dir);
$dirOpt->closeDir($dir);?>

function explorer($dir)
{
    $list  = array();
    $files = array();
    $dirs  = array();    $dp = opendir($dir);    $list['name'] = $dir;    while ($file = readdir($dp))
    {
        if ($file != '.' && $file != '..')
        {
            $path = $dir . '/' . $file;
            if(is_dir($path))
            {
                $dirs[] = explorer($path);
            }
            else
            {
                $files[] = $path;
            }
        }
    }    closedir($dp);    $list['files'] = $files;
    $list['dirs'] = $dirs;    return $list;
}print_r(explorer('C:\Program Files\PHP'));
