将分钟添加到日期时间无法正常工作

Question

我正在处理Yii2。在其中，我试图将数据插入 3 个不同的阶段。即我正在一个一个地使用 3 个查询来插入不同类型的数据。数据插入是完美的，但日期时间不是。由于我想连续添加数据，所以我添加了for loop。但是它插入的日期时间总是相同的。请参阅下面的代码

for ($i = 0; $i <= 60; $i++) 
{
  $dt = date('Y-m-d H:i:s');
 $model401->data_date_time = date('Y-m-d H:i:s', strtotime('+5 minutes', strtotime($dt)));
 $model402->data_date_time = date('Y-m-d H:i:s', strtotime('+10 minutes', strtotime($dt)));
 $model403->data_date_time = date('Y-m-d H:i:s', strtotime('+15 minutes', strtotime($dt)));
.
.
.
.
.
.
}

保存在数据库中的日期时间是相同的，即

2020-04-25 11:11:57首次记录日期

2020-04-25 11:16:57第二个记录日期

2020-04-25 11:21:57第三个记录日期

2020-04-25 11:11:57第四次记录日期

2020-04-25 11:16:57第五个记录日期

2020-04-25 11:21:57第六次记录日期

            $model403->save();


        }

    }
    }

您可以看到第一个到第三个和第四个到第六个日期时间是相同的。如何准确设置日期时间？

任何帮助将不胜感激。

自定义这个：

$dt = date('Y-m-d H:i:s');
echo $dt . '<br>'; //now
$min5Later = strtotime('+5 minutes', strtotime($dt));//5 min later from $dt
$min5LaterFormat = date('Y-m-d H:i:s', $min5Later);

$min10Later = strtotime('+10 minutes', strtotime($dt));//10 min later from $dt
$min10LaterFormat = date('Y-m-d H:i:s', $min10Later);

$min15Later = strtotime('+15 minutes', strtotime($dt));//15 min later from $dt
$min15LaterFormat = date('Y-m-d H:i:s', $min15Later);

for ($i = 0; $i <= 2; $i++) {
    $min5Later = strtotime('+5 minutes', strtotime($min5LaterFormat));//5 min later from $min5later
    $min5LaterFormat = date('Y-m-d H:i:s', $min5Later);
    $min10Later = strtotime('+10 minutes', strtotime($min10LaterFormat));//10 min later from $min10later
    $min10LaterFormat = date('Y-m-d H:i:s', $min10Later);
    $min15Later = strtotime('+15 minutes', strtotime($min15LaterFormat));//15 min later from $min15later
    $min15LaterFormat = date('Y-m-d H:i:s', $min15Later);

 echo $min5LaterFormat . ' | ';
 echo $min10LaterFormat . ' | ';
 echo $min15LaterFormat . ' | <br>';
}

输出：
