$arr = array("a", "new", "advanced", "operating", "system", "for", "PC", "MAC", "and", "Linux");
  
$chunks = array_chunk($arr, 3);
 
for ($row = 0; $row < count($chunks); $row++) {
  echo "\n--- Chunk : $row" . "\n";
  for ($col = 0; $col < count($chunks[$row]); $col++) 
        echo $chunks[$row][$col] . "\n";
}
