php - 在时间戳和日期时间之间转换

Question

我试过这段代码，它会给我正确的日期，但时间不正确:

function convert_datetime($str) { 

    list($date, $time) = explode(' ', $str); 
    list($year, $month, $day) = explode('-', $date); 
    list($hour, $minute) = explode(':', $time); 
    $timestamp = mktime($hour, $minute, $year, $month, $day); 
    return $timestamp; 
}  
    if(isset($_POST['submit']))
    {
    $datetime=$_POST['startdate'].' '.$_POST['start_hour'].":".$_POST['start_minute'];
    $timestamp=convert_datetime($datetime);
    echo "DateTime:".$datetime;
    echo " ";
    echo "Timestamp:".$timestamp;
    echo " ";
    $dateandtime = date("Y-m-d H:i", $timestamp);
    echo "converted:".$dateandtime;
    }

输入:2013-1-21 21:51我会把这个拿出来

DateTime:2013-1-21 21:51 Timestamp:1358807073 converted:2013-01-21 22:24

所以顺序不正确。在时间部分我遇到了问题。如何解决这个问题？

使用Datetime .它更容易也更准确:

$datetime = DateTime::createFromFormat("Y-m-d H:i", '2013-1-21 21:51');
echo 'Timestamp: ' . $datetime->getTimestamp() . PHP_EOL;
echo 'Datetime: ' . $datetime->format("Y-m-d H:i") . PHP_EOL;

Confirmed working
