上面我們講到了,Deletefile()函數,下面我們接著講Createfolder()函數

function Createfolder($path,$nname){
 if(is_dir($path) && is_writable($path)){//是否為目錄且可寫
  if(preg_match("/^\w{1,255}$/i",$nname)){//判斷文件的合法性
   echo mkdir($path."/".$nname,0777)?'Create Folder success':'Create Folder Fail';//0777是設置文件可讀寫
  }else{
   echo "Folder Error";
  }
 }else{
  echo "Can't Create Error file not is_writable or not dir";
 }}

這個函數的功能是實現文件夾的建,

Past($path,$nname,$cpath)函數

function Past($currentpath,$currentfilename,$filepote){ //1:文件要被粘貼到的位置2:當前文件{夾}名3:文件{夾}所在的物理地址  
  $str = substr($currentfilename,-1,1);
  if(substr($currentfilename,-1,1)=="|"){
   $currentfilename = str_replace("|","",$currentfilename);
   $filepote   = str_replace("|","",$filepote);
  }
  if(is_dir($currentpath) && is_writable($currentpath) && is_dir($filepote) && is_writable($filepote)){
   //@mkdir($currentpath."/".$currentfilename);
   $t=full_copy($filepote,$currentpath."/".$currentfilename)?'t':'f';//full_copy函數下面接,是進行遞歸讀取文件夾
  }else if(is_file($filepote) && file_exists($filepote)){
   if(file_exists($currentpath.$currentfilename)){ echo ('file exists! plase rename it!');exit;}
    echo copy($filepote,$currentpath.$currentfilename)?'success':'errror';  
}  if( $str =="|" && $t='t' ){ 
   deldir($filepote);
  }
}

function full_copy( $source, $target )//這個函數來自php官方站,功能是進行文件夾遞歸拷貝文件
    {

        if ( is_dir( $source ) )
        {
            @mkdir( $target ); 
            $d = dir( $source );
            while ( FALSE !== ( $entry = $d->read() ) )
            {
            if ( $entry == '.' || $entry == '..' )
                {
                        continue;
                }
                $Entry = $source . '/' . $entry;
                if ( is_dir( $Entry ) )
                {
                   full_copy( $Entry, $target . '/' . $entry );
                    continue;
                }
                copy( $Entry, $target . '/' . $entry );
            }
            $d->close();
        }else {
            copy( $source, $target );
        }
    }
