Php 一步完成数组计数、求和和和顺序

我有一个表示足球比赛“结果”的数组（team1——用数字表示的名称和team1_积分，表示该队从这场比赛中获得的分数（3分表示胜利，1分表示平局，0分表示失败）

代码如下：

  array (size=9)
  0 => 
    array (size=2)
      'team1' => string '2' (length=1)
      'team1_points' => string '0' (length=1)
  1 => 
    array (size=2)
      'team1' => string '2' (length=1)
      'team1_points' => string '0' (length=1)
  2 => 
    array (size=2)
      'team1' => string '2' (length=1)
      'team1_points' => string '0' (length=1)
  3 => 
    array (size=2)
      'team1' => string '14' (length=2)
      'team1_points' => string '0' (length=1)
  4 => 
    array (size=2)
      'team1' => string '14' (length=2)
      'team1_points' => string '3' (length=1)
  5 => 
    array (size=2)
      'team1' => string '1' (length=1)
      'team1_points' => string '3' (length=1)
  6 => 
    array (size=2)
      'team1' => string '13' (length=2)
      'team1_points' => string '1' (length=1)
  7 => 
    array (size=2)
      'team1' => string '5' (length=1)
      'team1_points' => string '1' (length=1)
  8 => 
    array (size=2)
      'team1' => string '7' (length=1)
      'team1_points' => string '0' (length=1)

正如您所看到的，一些团队1正在重复，例如'team1'=>'2'是否有3次，id=“14”的团队是否有2次'team1'=>'14'等

我需要根据team1列对相同的团队进行分组（具有相同id的团队，例如2或14等，并创建一个新的别名列，名为team_1_出现次数tht将保存数组中该团队的数量，以及一个列，例如team1_总积分，该列将汇总所有team1_积分（3,1或0）

然后按团队订购1\u总积分\u列描述

所以，最后我需要这样的东西：

team1 | team1_occurrences | team1_total_points
----------------------------------------------
14    | 2                 | 3
----------------------------------------------
2     | 3                 | 0

我从while循环创建的数组只包含两列team1和team1\u points（结果是问题开头的var\u转储：

$matches_array[] = array(
     'team1'=> $team_1_id,
     'team1_points'=> $team1_points
);

我想我需要以某种方式使用php函数数组\u计数\u值并创建一个新列，但我不知道如何创建

提前感谢您提供解决此问题的建议。

您可以试试

$array = array(
        0 => array('team1' => '2','team1_points' => '1'),
        1 => array('team1' => '2','team1_points' => '1'),
        2 => array('team1' => '2','team1_points' => '0'),
        3 => array('team1' => '14','team1_points' => '0'),
        4 => array('team1' => '14','team1_points' => '3'),
        5 => array('team1' => '1','team1_points' => '3'),
        6 => array('team1' => '13','team1_points' => '1'),
        7 => array('team1' => '5','team1_points' => '1'),
        8 => array('team1' => '7','team1_points' => '1'));



$list = array();

array_map(function($var){}, $array);
foreach ( $array as $value ) {
    $key = $value['team1'];

    if (array_key_exists($key, $list)) {
        $list[$key]['team1_points'] += $value['team1_points'];
        $list[$key]['team_1_occurrences'] ++;
    } else {
        $list[$key] = $value;
        $list[$key]['team_1_occurrences'] = 1;
    }
}

usort($list ,function($a, $b){ $a = $a['team1_points'] ; $b = $b['team1_points'] ; return ($a == $b) ? 0 : (($a < $b) ? 1 : -1 ) ;});
var_dump($list);

现在，你这样做有什么问题吗？等等，我会用我当前的代码更新我的问题，让它更清楚。再说一遍，问题是什么？还有，你是从数据库获取数据吗？如果是这样，那么在数据库级做这些事情会更容易，也更有效。好的，更新了。我的问题是我不知道acc应该使用哪些函数完成我需要的。因此，我在这里征求一些建议。不，我正在为WP使用pods框架，它们有一个bug，所以我不能使用count或sum，因为它总是在t.prefix等前面加前缀。说来话长。我现在需要使用数组来绕过它。@Derfder如果您需要任何改进，请告诉我。到目前为止，它似乎有效。我认为例如，“team\u 1\u事件数”=>int 0应该是“team\u 1\u事件数”=>int 1。您认为为每个事件添加1可以解决问题吗？更新的代码给了我一个错误：警告：array\u key\u exists（）期望参数2为array:（.有什么建议如何修复它吗？不管怎样，我忘了包含$list-array（）；现在它可以工作了。但是，如何根据点而不是发生次数对其进行排序，有时在变量转储中，它是'team1_points'=>string'3'（长度=1），有时只是'team1_points'=>int 3。为什么？
