在 PHP 中为给定小时添加 15 分钟间隔

Question

我有一个集合，其中包含像这样的商店的开盘和关门时间：

"Monday" => array:2 [▶]
"Tuesday" => array:2 [▼
"open_at" => "09:00"
"close_at" => "18:00"
]
"Wednesday" => array:2 [▶]
"Thursday" => array:2 [▶]
"Friday" => array:2 [▶]
"Saturday" => array:2 [▶]
"Sonday" => array:2 [▶]

我想在店主决定的每一天时间间隔(约会(中添加。假设每 15 分钟。我想得到这样的东西：

"Tuesday" => array:2 [▼
"open_at" => "09:00"
2  => "09:15"
3  => "09:30"
.... all in between...
31  => "17:30"
32  => "17:45"
"close_at" => "18:00"
]

我的问题是数据类型是字符串。 我试图用碳解析它(我正在使用拉拉维尔(，但我得到错误：

Trailing Data. Data Missing

我尝试使用纯PHP，但我惊讶于(strtotime('00:15:00')等于1576023300而不是54000秒。

无论如何，我继续这样做：

if($weekdays[ $index] === 'Tuesday') {
$open = strtotime($day->open_at);
$close = strtotime($day->close_at);
$interval = array();
// I get 15 minutes in seconds: (strtotime('00:15:00')) == 1576023300 
for ($i=$open; $i < $close; $i + 1576023300) { 
$interval[$i] = gmdate("H:i", $i);
}
};

但我不明白。而这种来回和前进，加上循环和if()功能非常容易出错。

我的问题是：

(

• strtotime('00：15：00'(等于1576023300而不是54000秒是否正确？
• 有没有更聪明/神奇的方法可以在给定的小时内增加 15 分钟，直到它到达结束小时？

Answer 1

您可以使用DateTime和DateInterval类来做到这一点。

if ($weekdays[$index] === 'Tuesday') {
$tuesday = [
'open_at' => $day->open_at, // 09:00
'close_at' => $day->close_at, // 18:00
];
$interval = (new DateTime($day->open_at))->add(new DateInterval('PT15M'))->format('H:i'); // adds 15 mins to 09:00
$i = 2; //index
while ($interval < '18:00') {
$tuesday[$i] = $interval;
$interval = (new DateTime($interval))->add(new DateInterval('PT15M'))->format('H:i');
$i++;
}
};

最后你可以订购$tuesday：asort($tuesday);.

Answer 2

希望这能解决您对问题的回答:)

$str_time = "00:15:00";
$str_time = preg_replace("/^([d]{1,2}):([d]{2})$/", "00:$1:$2", $str_time);
sscanf($str_time, "%d:%d:%d", $hours, $minutes, $seconds);
$time_seconds = $hours * 3600 + $minutes * 60 + $seconds;

Answer 3

这是一个相当简单的实现(只有 2 天用于测试目的(。这会将所有开始时间(包括open_at(添加到带有数字索引的数组中，以便更轻松地迭代它们：

$days = array('Monday'  => array('open_at' => '09:00', 'close_at' => '18:00'),
'Tuesday' => array('open_at' => '11:00', 'close_at' => '14:00')
);
foreach ($days as &$day) {
$time = new DateTime($day['open_at']);
$close = new DateTime($day['close_at']);
while ($time < $close) {
$day[] = $time->format('H:i');
$time->modify('+15 minutes');
}
}
print_r($days);

输出：

[Monday] => Array

[open_at] => 09:00
