Directory traverse/sorting problem

[nucleardreamer]

Hi guys, I seem to be having a problem with this function that spits out directories. There is a numeric prefix that is on every directory, so it automatically sorts these by the numbers, not the name of the actual folder I want to display. So to sort correctly I did the following (and I know it works right because the array is the same but sorted different) but every time I do it, it gives me a 500 error and the error.log tails that the header is prematurely broken, I dont know whats causing it!

 

One thing that is possibly (or more likely) is that the directory names are somehow different, there is a space somewhere i don't know... something?!

 

//example foldername: -20090101N-TestFolder

// I want it to sort by TestFolder not the starting date of the name.

 

function traverseDirTree($base,$fileFunc,$dirFunc=null,$afterDirFunc=null){

        // this is the spot where the prefix ends

        $scan_index=11;

        // puts the dir from $base into an array

        $subdirectories = scandir($base);

 

    // breaks the array apart, putting the original prefix at the end, and stores a temp array

foreach($subdirectories as $myscan){

if ($myscan != "." && $myscan != "..") {

$newScan = substr($myscan,$scan_index).substr($myscan,0,$scan_index);

$scan_temp[]=$newScan;

}

}

// sort the temp dir, and empty the original array

sort($scan_temp);

$subdirectories = array();

 

// put the prefix back in the beginning after its sorted

foreach($scan_temp as $scan){

    $newScan = substr($scan,(0-$scan_index),$scan_index).substr($scan,0,(0-$scan_index));

    $subdirectories[]=$newScan;

}

 

// this traverses the directory, looking for files and subdirectories, then running the script again for every subdir

foreach ($subdirectories as $subdirectory){

if ($subdirectory != "." && $subdirectory != "..") {

$path=$base.$subdirectory;

if (is_file($path)){

  if ($fileFunc!==null) $fileFunc($path);

}else{

  if ($dirFunc!==null) $dirFunc($path);

  if (($subdirectory!='.') && ($subdirectory!='..')){

traverseDirTree($path.'/',$fileFunc,$dirFunc,$afterDirFunc);

  }

  if ($afterDirFunc!==null) $afterDirFunc($path);

}

    }

  }

}
