Solution in PHP (judge verdict: Wrong Answer)

<?php
if (basename(__FILE__) == basename($_SERVER['PHP_SELF'])) {
  while ($line = fgets(STDIN)) {
      $array = explode(' ', $line);
      sort($array);
      foreach ($array as $val) {
        echo $val . ' ';
      }
//      echo implode(' ', $array);
  }
