Question

我有一个字符串，它将dateTime作为一个GROUP从数据库中获取，所以我得到类似这样的东西

2017-10-20 05:00:00,2017-10-20 09:00:00,2017-10-20 07:00:00,2017-10-20 13:30:00,2017-10-20 16:00:00,2017-10-20 13:00:00,2017-10-20 06:00:00,2017-10-20 09:30:00,2017-10-20 10:30:00,2017-10-20 15:30:00,2017-10-20 17:00:00

请注意，所有日期都相同，即2017-10-20。因为我不需要担心不同的日期。我想要的只是简单地从这个字符串中提取时间，并像这样很好地打印它

05:00, 09:00, 07:00, 13:30, 16:00 //and so on

我不想要秒，这是不必要的。

我尝试使用PHP的strtotime（）函数，但它失败并改为00:00:00。

有什么想法吗？我使用Laravel作为模板引擎。

Answer 1

在您的SQL语句中执行此操作。

SELECT TIME_FORMAT(`dateColumn`, '%H:%i') FROM ...

Answer 2

一步一步：

$dateTimes = '2017-10-20 05:00:00,2017-10-20 09:00:00,2017-10-20 07:00:00,2017-10-20 13:30:00,2017-10-20 16:00:00,2017-10-20 13:00:00,2017-10-20 06:00:00,2017-10-20 09:30:00,2017-10-20 10:30:00,2017-10-20 15:30:00,2017-10-20 17:00:00';
$dateTimesArray = explode(',', $dateTimes);
$timesArray = [];
foreach($dateTimesArray as $dateTime) {
    $timesArray[] = date('H:i', strtotime($dateTime));
}
$times = join(',', $timesArray);

<?php
$tGroup = "2017-10-20 05:00:00,2017-10-20 09:00:00,2017-10-20 07:00:00,2017-10-20 13:30:00,2017-10-20 16:00:00,2017-10-20 13:00:00,2017-10-20 06:00:00,2017-10-20 09:30:00,2017-10-20 10:30:00,2017-10-20 15:30:00,2017-10-20 17:00:00";

$retVal = "";
$dates = explode(",", $tGroup);
foreach ($dates as $date) {
    $time = date('H:i', strtotime($date));

    // use this if you want to print AM/PM format
    //$time = date('h:i A', strtotime($date));

    $retVal .= $time . ", ";
}
echo trim($retVal," ,");
