Question

大家好，我过去几个小时一直在努力解决这个问题我有这个数组

Array ( 
        [0] => Array ( [countThis_id] => 1 [icon] => add.gif [url] => add.php)
        [1] => Array ( [countThis_id] => 1 [icon] => add.gif [url] => add.php)
        [2] => Array ( [countThis_id] => 2 [icon] => add.gif [url] => add.php)
        [3] => Array ( [countThis_id] => 2 [icon] => add.gif [url] => add.php)
        [4] => Array ( [countThis_id] => 5 [icon] => add.gif [url] => add.php)
        [5] => Array ( [countThis_id] => 6 [icon] => add.gif [url] => add.php)
        [6] => Array ( [countThis_id] => 7 [icon] => add.gif [url] => add.php)
        [7] => Array ( [countThis_id] => 7 [icon] => add.gif [url] => add.php)     
      )

所以我想在这里做的是在某些条件下计算匹配的[countThis_id] 例如：

      count first = if  [countThis_id] == 2 
      count second = if  [countThis_id] == 1 
      count the rest ignoring the matchs

继承人我想要的最终结果

Array ( 
    [0] => Array ( [countThis_id] => 1 [icon] => add.gif [url] => add.php)
    [1] => Array ( [countThis_id] => 1 [icon] => add.gif [url] => add.php)
    [2] => Array ( [countThis_id] => 2 [icon] => add.gif [url] => add.php)
    [3] => Array ( [countThis_id] => 2 [icon] => add.gif [url] => add.php)
    [4] => Array ( [countThis_id] => 5 [icon] => add.gif [url] => add.php)
    [5] => Array ( [countThis_id] => 6 [icon] => add.gif [url] => add.php)
    [6] => Array ( [countThis_id] => 7 [icon] => add.gif [url] => add.php)
    [7] => Array ( [countThis_id] => 7 [icon] => add.gif [url] => add.php)   
    [8] => Array ( [count_1] => 2 [count_2] => 2 [the_Rest] => 4)   
  )

任何想法？谢谢你

$result = array('count_1' => 0, 'count_2'=>0, 'the_Rest'=>0);
foreach($array as $arr){
   if($arr['countThis_id'] == 2){
     $result['count_1']++;
   }
   else if($arr['countThis_id'] == 1){
     $result['count_1']++;
   }
   else {
     $result['the_rest']++;
   }
}

array_push($array, $result);
var_dump($array);

对于排序，您可以使用array_multisort()
