我有一个时间"7:00 am"，需要将其划分为$hour、$min和$ampm。有没有一种简单的方法可以把它分成3个变量？
$a = preg_split('/[: ]/', '7:00 am');
$hour = $a[0][0];
$minute = $a[1][0];
$ampm = $a[2][0];
$yourtime = "7:00 am";
preg_match("/([0-9]{1,2}):([0-9]{1,2}) ([a-zA-Z]+)/", $yourtime, $match);
$hour = $match[1];
$min = $match[2];
$ampm = $match[3];
$time = '7:00 am';
list ($time, $ampm) = explode(' ', $time);
list ($hour, $min) = explode(':', $time);
sscanf( "7:00 am", "%d:%d %s", $hour, $min, $ampm );
$time = '7:00 am';
$hour = date("g",$time);
$min = date("i",$time);
$ampm = date("a",$time);
