Question

I have a one core php file in which i want to get file name in a particular folder with order like,
I have many files but each file name like filename_0,filename_1,filename_2 like this so when ever i fetch file name in folder that is not proper order and i am getting filename_0,filename_2,filename_1..

    $dir_path="/var/lib/myproject";
        $folder=dir("$dir_path");
                    $j=0;$allfilename='';
                    while($folderEntry=$folder->read())
                    {
                        if($folderEntry == '.' || $folderEntry == '..' )
                        {
                        continue;
                        }else{
echo "Path of directory is>>>>>>>>".$folderEntry;
                        $allfilename[]=$folderEntry;
                        $j++;
                        }
                    }
  $folder->close();

i can fetch file name but not getting order so any order loke incremented filename_0 to continue file name …..
so can any one any idea how to get file name with ascending order.

You can always natsort the filename array.

natsort($allfilename);

Note here natural sort is necessary as you might want to consider filename_1 is before filename_100. Another option is using sort function.

sort($allfilename, SORT_NATURAL);
