            echo '<span style="color: red;font-weight:bold;">' . str_repeat("--", $level) . $subPath . '</span>';

五、选择排序


<"htmlcode">

<"htmlcode">

<?php
function quickSort($arr) {
  $len = count($arr);
 
  if($len <= 1) return $arr;
 
  $base_num = $arr[0];
  $left_array = [];
  $right_array = [];
  for($i=1; $i<$len; $i++) {
    if($base_num > $arr[$i]) {
      $left_array[] = $arr[$i];
    } else {
      $right_array[] = $arr[$i];
    }
  }
  $left_array = self::quickSort($left_array);
  $right_array = self::quickSort($right_array);
  return array_merge($left_array, array($base_num), $right_array);
}
