Question

我这里有一个非常奇怪的问题。很抱歉这些丑陋的冗余部件，但它只适用于原型设计。在两个块中，我计算给定工作时间的秒数。第一个版本是第一个版本并且工作，但不是那么强大。所以第二个块解决了鲁棒性问题。重要的是 $hours[$row["gamemaster"]] = $hours[$row["gamemaster"]] + $worktime;

在两个块中，整数$ worktime以秒为单位。但现在问题是，在第二个块中，工作时间的总和不起作用。它处于同一级别，代码的其他部分没有变化。

预期值是每个游戏管理员的工作时间总和。在第一个块中，打印值是预期的时间，在第二个块中没有任何反应。我的大问号是，总和的计算完全相同，只有之前工作时间的计算是不同的。如果我在第二个块中只添加正常整数，如$hours[$row["gamemaster"]] = $hours[$row["gamemaster"]] + 1;则没有任何反应，但对于第一个块，还有像$hours[$row["gamemaster"]] = $hours[$row["gamemaster"]] + "p";这样奇怪的东西。

第一块：

if($row["no_game"]==0) {
    $worktime = strtotime($row["additional"]);
    $worktime = $worktime + 5400;

    $hours[$row["gamemaster"]] = $hours[$row["gamemaster"]] + $worktime;
  }
  else {
    $worktime = strtotime($row["additional"]);

    $hours[$row["gamemaster"]] = $hours[$row["gamemaster"]] + $worktime;
  }

以小时为单位输出第一个块：
[关键]：[价值]
费利克斯：8778047400
玛丽：2926018800

第二块：

  if($row["no_game"]==0) {
    $str_time = $row["additional"];
    $str_time = preg_replace("/^([\d]{1,2})\:([\d]{2})$/", "00:$1:$2", $str_time);
    sscanf($str_time, "%d:%d:%d", $hours, $minutes, $seconds);
    $time_seconds = $hours * 3600 + $minutes * 60 + $seconds;
    $worktime = $time_seconds + 5400;

    $hours[$row["gamemaster"]] = $hours[$row["gamemaster"]] + $worktime;
  }
  else {
    $str_time = $row["additional"];
    $str_time = preg_replace("/^([\d]{1,2})\:([\d]{2})$/", "00:$1:$2", $str_time);
    sscanf($str_time, "%d:%d:%d", $hours, $minutes, $seconds);
    $worktime = $hours * 3600 + $minutes * 60 + $seconds;

    $hours[$row["gamemaster"]] = $hours[$row["gamemaster"]] + $worktime;
  }

输出第二个块$ $：什么都没有，就像在数组中写的一样

更新1：我将第二个块的代码减少到

    $str_time = $row["additional"];
    $str_time = preg_replace("/^([\d]{1,2})\:([\d]{2})$/", "00:$1:$2", $str_time);
    sscanf($str_time, "%d:%d:%d", $hours, $minutes, $seconds);
    $time_seconds = $hours * 3600 + $minutes * 60 + $seconds;
    $worktime = $time_seconds + 5400;Update 1:

    $worktime = $time_seconds + 5400;
    $hours[$row["gamemaster"]] = $hours[$row["gamemaster"]] + $worktime;

数据集上有8次迭代，每次迭代的$ worktime输出为：
1：7200
2：5400
3：5400
4：7200
5：7200
6：7200
7：5400
8：5400

但是在几小时内仍然没有进入。

问题是您正在覆盖$hours来电中的sscanf变量。

$rows = [
    ['gamemaster' => 1, 'additional' => '00:30:00', 'no_game' => 0],
    ['gamemaster' => 2, 'additional' => '00:10:30', 'no_game' => 0],
    ['gamemaster' => 3, 'additional' => '00:20:00', 'no_game' => 0],
    ['gamemaster' => 1, 'additional' => '00:40:40', 'no_game' => 1],
    ['gamemaster' => 2, 'additional' => '00:15:00', 'no_game' => 1],
    ['gamemaster' => 3, 'additional' => '00:00:30', 'no_game' => 1],
    ['gamemaster' => 1, 'additional' => '00:00:10', 'no_game' => 0],
    ['gamemaster' => 2, 'additional' => '00:20:30', 'no_game' => 0],
    ['gamemaster' => 3, 'additional' => '00:00:00', 'no_game' => 0],
    ['gamemaster' => 1, 'additional' => '00:05:00', 'no_game' => 1],
    ['gamemaster' => 2, 'additional' => '00:09:40', 'no_game' => 1],
    ['gamemaster' => 3, 'additional' => '00:18:30', 'no_game' => 1],
    ['gamemaster' => 1, 'additional' => '00:34:30', 'no_game' => 0],
    ['gamemaster' => 2, 'additional' => '00:59:59', 'no_game' => 0],
    ['gamemaster' => 3, 'additional' => '00:40:00', 'no_game' => 0]
];

$result = array();

foreach ($rows as $row) {
    $str_time = preg_replace('/^([\d]{1,2})\:([\d]{2})$/', "00:$1:$2", $row['additional']);
    sscanf($str_time, '%d:%d:%d', $hours, $minutes, $seconds);
    $worktime = $hours * 3600 + $minutes * 60 + $seconds;
    if (!$row['no_game']) {
        $worktime += 5400;
    }
    if (!isset($hours[$row['gamemaster']])) {
        $result[$row['gamemaster']] = 0;
    }
    $result[$row['gamemaster']] += $worktime;
}

var_dump($result);

PHP关联数组，同一级别的相同代码不起作用
