มีวิธีการ copy file ทั้ง folder ด้วย php ไหมครับ ปกติเวลาจะ copy file ก็จะใช้คำสั่ง copy(file_tmp,path) มันจะมาไฟล์เดียว

<?php
function dir_copy($srcdir, $dstdir, $offset = '', $verbose = false) 
{ 
    // A function to copy files from one directory to another one, including subdirectories and 
    // nonexisting or newer files. Function returns number of files copied. 
    // This function is PHP implementation of Windows xcopy  A:\dir1\* B:\dir2 /D /E /F /H /R /Y 
    // Syntaxis: [$returnstring =] dircopy($sourcedirectory, $destinationdirectory [, $offset] [, $verbose]); 
    // Example: $num = dircopy('A:\dir1', 'B:\dir2', 1); 

    // Original by SkyEye.  Remake by AngelKiha. 
    // Linux compatibility by marajax. 
    // ([danbrown AT php DOT net): *NIX-compatibility noted by Belandi.] 
    // Offset count added for the possibilty that it somehow miscounts your files.  This is NOT required. 
    // Remake returns an explodable string with comma differentiables, in the order of: 
    // Number copied files, Number of files which failed to copy, Total size (in bytes) of the copied files, 
    // and the files which fail to copy.  Example: 5,2,150000,\SOMEPATH\SOMEFILE.EXT|\SOMEPATH\SOMEOTHERFILE.EXT 
    // If you feel adventurous, or have an error reporting system that can log the failed copy files, they can be 
    // exploded using the | differentiable, after exploding the result string. 
    //
