readdir() sort in php

[shady]

I'm having great difficulty sorting an array in php. Can anybody help me please:

echo "  var pixList=new Array();\n";
$dir=opendir($albums_root_dir."/".$album_dir);
$i=0;
while($entry=readdir($dir)) if(is_image($albums_root_dir."/".$album_dir."/".$entry)){

  echo "  pixList[".$i."]=".get_MAImage($albums_root_dir."/".$album_dir."/".$entry,$max_miniature_width,$max_miniature_height,'').";\n";
  echo "  pixList[".($i++)."].imageFile='".$entry."'\n;";
