function move_d($source,$target){
if(is_dir($source)){
$dest_name=basename($source);
if(!mkdir($target.$dest_name)){
return false;
}
$d=dir($source);
while(($entry=$d->read())!==false){
if(is_dir($source.$entry)){
if($entry=="."||$entry==".."){
continue;
}else{
move_d("$source$entry//","$target$dest_name//");
}
}else{
if(!copy("$source$entry","$target$dest_name//$entry")){
return false;
}
}
}
}else{
if(!copy("$source$entry","$target$dest_name//")){
return false;
