How should this copy() able to skip a file

Posted on 2010-09-17

Hi experts,

I got this function smartCopy from php.net which works like charm but I really need to add a feature there that I dont know how to and I really need help with this.

So, here is how I applied to my script ... It is working great, copying all files in 'temp' folder to the folder beneath
smartCopy('./temp/', './', $options=array('folderPermission'=>0755,'filePermission'=>0755));

I wonder if you would modify the function for me so I can skip a file (or perhaps more) to not to be copied .. for example 'config.php' ... so perhaps the function can be modified and used like this:
smartCopy('./temp/', './', $options=array('folderPermission'=>0755,'filePermission'=>0755), $skipFile=array('config.php'));
So while copying all files it will skip 'config.php' ...

Thanks...

And below is the function codes :
function smartCopy($source, $dest, $options=array('folderPermission'=>0755,'filePermission'=>0755))
{ 
        $result=false;

        if (is_file($source)) {
            if ($dest[strlen($dest)-1]=='/') {
                if (!file_exists($dest)) {
                    cmfcDirectory::makeAll($dest,$options['folderPermission'],true);
                }
                $__dest=$dest."/".basename($source);
            } else {
                $__dest=$dest;
            }
            $result=copy($source, $__dest);
            chmod($__dest,$options['filePermission']);
           
        } elseif (is_dir($source)) {
            if ($dest[strlen($dest)-1]=='/') {
                if ($source[strlen($source)-1]=='/') {
                    //Copy only contents
                } else {
                    //Change parent itself and its contents
                    $dest=$dest.basename($source);
                    @mkdir($dest);
                    chmod($dest,$options['filePermission']);
                }
            } else {
                if ($source[strlen($source)-1]=='/') {
                    //Copy parent directory with new name and all its content
                    @mkdir($dest,$options['folderPermission']);
                    chmod($dest,$options['filePermission']);
                } else {
                    //Copy parent directory with new name and all its content
                    @mkdir($dest,$options['folderPermission']);
                    chmod($dest,$options['filePermission']);
                }
            }

            $dirHandle=opendir($source);
            while($file=readdir($dirHandle))
            {
                if($file!="." && $file!="..")
                {
                     if(!is_dir($source."/".$file)) {
                        $__dest=$dest."/".$file;
                    } else {
                        $__dest=$dest."/".$file;
                    }
                    //echo "$source/$file ||| $__dest<br />";
                    $result=smartCopy($source."/".$file, $__dest, $options);
                }
            }
            closedir($dirHandle);
        } else {
            $result=false;
        }
        return $result;

here is it...

This line does all the magic:

if (is_file($source) && (!in_array(pathinfo($source, PATHINFO_BASENAME), $options['Skip_File'])) )

I attached the full functional example, just execute the CopyDemo.php and see it do the Work, copying the content from Folder1 to Folder2, and skip the files specified.

and the function must be used like this:


$source	 = 'Folder1';
$dest	 = 'Folder2';
$options = array('folderPermission'=>0755,'filePermission'=>0755,'Skip_File' => array('DontCopyMe.txt', 'DontCopyMe1.txt', 'DontCopyMe2.txt', 'DontCopyMe3.txt'));

smartCopy($source, $dest, $options)

@knight00:

Your Solution is almost Ok, but it have a error in this part:

if (is_file($source) && !in_array($source,$skipFile))


You should use the pathinfo() function, in order to get just the file name from $source and compare it to the list of files to skip, in other way your script will only work when you are copying files in the same folder where the script is being executed or when full paths are specified in $skipFile.

So, take care, that is a mistake.

You're right ... actually I tried solution from @knight00 too but it just copy everything just like the original function.
So, thanks a lot for the help... really appreciated.
