我想使用时间函数time()来输出患者的预期等待时间。

我目前有以下字段;

 PatientID   Forename  Surname   Illness   Priority    Waiting Time 

如何将时间函数合并到PHP中以获取以下计算的当前时间;

 waiting time would be (the clock time - the arrival time)

在数据库中,您应该使用time()功能节省时间。这对排序和其他更好。 如果您想查看格式的日期,请使用date('G:ia', $time);

祝你好运。

您应该将epoch/unix时间存储在数据库中:

$the_time = time();

您可以将所有不同的时间戳存储为epoch/unix次,然后轻松将其转换为日期:

date( 'G:ia', $the_time );

您还可以使用epoch/unix次来轻松确定两个不同时间之间的距离:

$the_time_1 = "1363903644";
$the_time_2 = "1363900644";

$time_diff = $the_time_1 - $the_time_2;
$hours = $time_diff / 3600; // 60 * 60 = number of seconds in an hour
echo $hours . ' hours';

回应您处理等候时间的功能请求:

$the_time_1 = "1363903644";
$the_time_2 = "1362900644";

echo waiting_time( $the_time_1, $the_time_2 );

function waiting_time( $time_1, $time_2 ) {

    $time_diff  = $time_1 - $time_2;
    $days       = floor( $time_diff / 86400 ); // 60 * 60 * 24 = number of seconds in a day
    $time_diff -= $days * 86400;
    $hours      = floor( $time_diff / 3600 ); // 60 * 60 = number of seconds in a hour
    $time_diff -= $hours * 3600;
    $mins       = floor( $time_diff / 60 ); // 60 = number of seconds in a minute

    return( $days . ' days, ' . $hours . ' hours, ' . $mins . ' minutes' );

}
