Question

我有一系列球员和得分，阵列看起来像： -

$a = array(
    array('date' => '09-04-2018','item' => 'player 1', 'score' => '1'),
    array('date' => '09-04-2018','item' => 'player 2', 'score' => '2'),
    array('date' => '10-04-2018','item' => 'player 1', 'score' => '1'),
    array('date' => '10-04-2018','item' => 'player 2', 'score' => '2'),
    array('date' => '16-04-2018','item' => 'player 1', 'score' => '3'),
    array('date' => '16-04-2018','item' => 'player 2', 'score' => '4'),
    array('date' => '17-04-2018','item' => 'player 1', 'score' => '3'),
    array('date' => '17-04-2018','item' => 'player 2', 'score' => '4')
);

为简单起见，我只展示了2名玩家＆＃34;玩家1＆＃34;和＆＃34;球员2＆＃34;实际上有多个玩家

我想显示一个表，但可以选择按日，周或月显示分数，我需要将其放入数组中，以便将其传递给数据表。

所以一周的新数组看起来像： -

$c = array(
    array('date' => '15','item' => 'player 1', 'score' => '2'),
    array('date' => '15','item' => 'player 2', 'score' => '4'),
    array('date' => '16','item' => 'player 1', 'score' => '6'),
    array('date' => '16','item' => 'player 2', 'score' => '8')
);

我可以根据日期添加分数，但这是添加所有玩家而不是将每个玩家分开。

这是我到目前为止： -

<?php 
$view = 0;
$a = array(
    array('date' => '09-04-2018','item' => 'player 1', 'score' => '1'),
    array('date' => '09-04-2018','item' => 'player 2', 'score' => '2'),
    array('date' => '10-04-2018','item' => 'player 1', 'score' => '1'),
    array('date' => '10-04-2018','item' => 'player 2', 'score' => '2'),
    array('date' => '16-04-2018','item' => 'player 1', 'score' => '3'),
    array('date' => '16-04-2018','item' => 'player 2', 'score' => '4'),
    array('date' => '17-04-2018','item' => 'player 1', 'score' => '3'),
    array('date' => '17-04-2018','item' => 'player 2', 'score' => '4')
);

$c =[];
foreach ($a as $i => $b)
{
    $date = new DateTime($b['date']);
    $player = $b['item'];
    $score = $b['score'];

    $key = $i;

    if ($view == 1) //$view - 0 = day, 1 = week, 2 = month
    {
        $key = array_search($date, array_column($c, 'date'));
        if ($key !== false)
        {
            $score= $c[$key]['score'] + $score;
        }
        else
        {
            $key = count($c);
        }
    }
    $c[$key]['date'] = $date->format("W");
    $c[$key]['item'] = $player;
    $c[$key]['score'] = $score;
  }

echo '<pre>';
print_r($c);
echo '<pre>';

 ?>

我认为这会帮助你这将创建一个带有播放器的新阵列 - ＆gt;周 - ＆gt;分数很容易被吸引或回应＆＃34;因为它是＆＃34;。

//Week example

Foreach($arr as $val){
    $res[$val['item']][date("W", strtotime($val['date']))][] = $val['score'];
}
Var_dump($res);

通过更改日期功能，您可以使其以不同方式构建阵列假设您想要月份，请更改＆＃34; W＆＃34;到n，m，M或F. https://3v4l.org/MUjYV

编辑：
这应输出总和。

Foreach($res as $player => $time){
    Foreach($time as $timeperiod => $score){
        Echo $player. " ". $timeperiod ." " .  array_sum($score) ."\n";
    }
}

周

相同的代码只是日期字符不同。

显示周或月的项目总计
