ordering a file list

[elesueur]

Hi,

I'm using :

while(false !== ($filename = readdir($dir))) {
     echo 'blah blah';
}

On my windows system, folders are listed first, and files afterwards.

On my freebsd server, folders are listed at the bottom.

Is there anyway to order the list?

Put them all into a multidim array and then order by parts.

$test=
array (
  array (
    'dir' => '/home',
    'file' => 'file.php'
  ),
  array (
    'dir' => '/home/bubblenut',
    'file' => 'another.php'
  ),
  array (
    'dir' => '/home',
    'file' => 'another.php'
  )
);
for($i=0;$i<count($test);$i++) {
  $dir[]=&$test[$i]['dir'];
  $file[]=&$test[$i]['file'];
}
array_multisort($dir, SORT_ASC, SORT_STRING, $file, SORT_ASC, SORT_STRING, $test);

$test is now

Array
(
  [0] => Array
    (
      ['dir'] => '/home',
      ['file'] => 'another.php'
    ),
  [1] => Array
    (
      ['dir'] => '/home',
      ['file'] => 'file.php'
    )
  [2] => Array
    (
      ['dir'] => '/home/bubblenut',
      ['file'] => 'another.php'
    )
)

of course you'd populate the arrays as you read from the directory. This may be a little overkill for what you want but I've just discovered it for a problem I was having (here)with sorting multi-dim arrays.

would that be faster than doing two consecutive directory reads, and just doing this:

while(false !== ($filename = readdir($dir))) {
     if(is_dir($path.'/'.$filename) {
          echo $filename;
     }
}
while(false !== ($filename = readdir($dir))) {
     if(!is_dir($path.'/'.$filename) {
          echo $filename;
     }
}

?? I guess its a matter of speed, and cleanliness.
Your way doesn't do the same job twice, my way is simple 🙂
