PHP - 按字母排序数组，但将具有0值的数组移到最后

Question

I have those 2 functions and I need to build a new one that will

• first sort the array by Name

• and then move the values with ['countValue'] = 0 to the end

  public function sortOptionsByName($a, $b)
  {
      $x = trim($a['label']);
      $y = trim($b['label']);
  
      if ($x == '') return 1;
      if ($y == '') return -1;
  
      if (is_numeric($x) && is_numeric($y)){
          if ($x == $y)
              return 0;
          return ($x > $y ? 1 : -1);
      }
      else {
          return strcasecmp($x, $y);
      }
  }
  
  
  public function sortOptionsByCounts($a, $b)
  {
      if ($a['countValue'] == $b['countValue']) {
          return 0;
      }
  
      return ($a['countValue'] < $b['countValue'] ? 1 : -1);
  }
  

Something like...

public function sortOptionsByCountsAndByName($a, $b)
{
    if ($a['countValue'] == 0 &&  $b['countValue'] == 0) {
        return -2
    }
    else {
        $this->sortOptionsByName($a, $b)
    }        
}

First compare values with zero. PHP casts boolean to integer, so you can just subtract to get -1, 0 , 1. And then compare another value when thw 1st comparing returns 0

public function sortOptionsByCountsAndByName($a, $b)
{
    $res = ($a['countValue'] == 0) - ($b['countValue'] == 0);
    return ($res ? $res : $this->sortOptionsByName($a, $b));
}
