突然发现这代码我写过n遍了，真不爽。。。

<?php

$dirname = "ooxx";
$pattern = 'google';
$replace = 'baidu';
$DontReplace = true;

replace_rec($dirname);

function replace_rec($dirname, $layer = 0){ 
    global $DontReplace;
    static $cnt = 0;
    $dir = scandir($dirname);
    natcasesort($dir);
    foreach($dir as $item){
        if($item == '.' || $item == '..') continue;
        $path = "$dirname/$item";
        if(is_dir($path)){
            replace_rec($path, $layer+1);
        }else if(is_file($path)){
            $str = file_get_contents($path);
            if(strpos($str, $pattern) === false) continue;
            if($DontReplace == false){
                $str = str_replace($pattern, $replace, $str);
                file_put_contents($path, $str);
            }   
            $cnt++;
            for($i = 0; $i < $layer; $i++) echo '  '; echo "$cnt: $path\n";
        }else{
            echo "UNKNOWN TYPE\n";
        }   
    }   
}
?>
