数据库备份的另一种方式，开拓思路。

<?php
$from_dir="D:/MySQL/data/dedecms";
$date = date("Ymd");
$to_dir="D:/bak/dd_" . $date;

 if(xCopy($from_dir,$to_dir,1)){
    echo '备份完成';
 }
function xCopy($source, $destination, $child){
    //$child = 1 包括子目录
    if(!is_dir($source)){
    echo("Error:the $source is not a direction!");
    return 0;
    }
    if(!is_dir($destination)){
    mkdir($destination,0777);
    }
    
    $handle=dir($source);
    while($entry=$handle->read()) {
        if(($entry!=".")&&($entry!="..")){
            if(is_dir($source."/".$entry)){
                if($child)    xCopy($source."/".$entry,$destination."/".$entry,$child);
            }else{
                copy($source."/".$entry,$destination."/".$entry);
            }
        }
    }
    return true;
