Question

我有一个类似

的数组

Array
(
    [0] => Array
        (
            [id] => 21
            [time] => FOUR_DAY
            [zones] => 25
        )

    [1] => Array
        (
            [id] => 20
            [time] => THREE_DAY
            [zones] => 2
        )
    [2] => Array
        (
            [id] => 22
            [time] => ONE_DAY
            [zones] => 2
        )
    [3] => Array
        (
            [id] => 24
            [time] => ONE_DAY
            [zones] => 2
        )
)

我需要的是

1-按时间排序＆＃39;字段，使用

$time = array('ONE_DAY','TWO_DAYS','THREE_DAYS','FOUR_DAYS','FIVE_DAYS');

2-然后按照以下区域对上述结果进行排序＆＃39;按照ASC顺序。

预期产出：

Array
(
    [0] => Array
        (
            [id] => 22
            [time] => ONE_DAY
            [zones] => 2
        )

    [1] => Array
        (
            [id] => 24
            [time] => ONE_DAY
            [zones] => 2
        )
    [2] => Array
        (
            [id] => 20
            [time] => THREE_DAY
            [zones] => 2
        )
    [3] => Array
        (
            [id] => 21
            [time] => FOUR_DAY
            [zones] => 25
        )
)

请帮我一个好的选择。我曾经尝试过usort的时间＆＃39;字段和multi_sort函数。但卡住了。在此先感谢!!

Answer 1

您应该使用usort来完成这项工作。

尝试类似：

$sorted = usort($notSorted, function($a, $b) {
    //array of times to compare
    $time = array('ONE_DAY','TWO_DAYS','THREE_DAYS','FOUR_DAYS','FIVE_DAYS');

    //check index of time in $times array
    $aKey = array_search($a['time'], $times);
    $bKey = array_search($b['time'], $times);

    //if the same - then compare by zones;
    if($aKey == $bkey) {
       return $a['zones'] - $b['zones'];
    //else compare by time's indexes
    } else {
      return ($aKey-$bKey);
    }
});

未通过测试显示出这个想法。

在PHP手册中查看usort的详细信息

Answer 2

  $order = array("ONE_DAY","TWO_DAY","THREE_DAY","FOUR_DAY");

  $test[4] =array("id"=>21,"time"=>"FOUR_DAY","zones"=>25);
  $test[1] =array("id"=>20,"time"=>"THREE_DAY","zones"=> 2);
  $test[2] =array("id"=>22,"time"=>"ONE_DAY","zones"=>2);
  $test[3] =array("id"=>24,"time"=>"ONE_DAY","zones"=>2);      

  $newarray=array();
  foreach($test as $kk=>$t){
    $newarray[$kk]=$t["time"];      
  }      

  $final=array();      
  foreach($order as $key=>$f){  
   $mykey=array_keys($newarray,$f);


   if(is_array($mykey)){
      foreach($mykey as $key){
        $final[]=$test[$key];
      }
   }   

  }  

  echo "<pre>";
  print_r($final);
  echo "</pre>";

Answer 3

全部谢谢!!我终于找到了解决问题的方法由于 $ time 具有预定义值，因此替换为

$time = array('ONE_DAY','TWO_DAYS','THREE_DAYS','FOUR_DAYS','FIVE_DAYS');

AS

$time = array(1=>'ONE_DAY',2=>'TWO_DAYS',3=>'THREE_DAYS',4=>'FOUR_DAYS',5=>'FIVE_DAYS');

使用 array_multisort 代替 usort

    `foreach($myArray as $key=>$response){`enter code here`
       $sortNumber = array_search($response['time'],$time);
       $myArray [$key]['numericTimes'] = ($sortNumber)?$sortNumber:"NULL";
       $sortByTime[$key] = array_search($response['time'],$time);
       $sortBtZone[$key] = $response['zones'];
     }`    
array_multisort($sortByTime, SORT_ASC, $sortBtZone, SORT_ASC, $myArray);

希望这在某些方面对某人有帮助!!
谢谢！

PHP使用外部数组按不同条件进行多种排序
