carbonを使う

use Carbon\Carbon;

使い方

$current = Carbon::now();
// get today - 2015-12-19 00:00:00
$today = Carbon::today();
// get yesterday - 2015-12-18 00:00:00
$yesterday = Carbon::yesterday();
// get tomorrow - 2015-12-20 00:00:00
$tomorrow = Carbon::tomorrow();
Carbon::createFromDate($year, $month, $day, $tz);
Carbon::createFromTime($hour, $minute, $second, $tz);
Carbon::create($year, $month, $day, $hour, $minute, $second, $tz);
$dt = Carbon::now();
$dt->year   = 2015;
$dt->month  = 04;
$dt->day    = 21;
$dt->hour   = 22;
$dt->minute = 32;
$dt->second = 5;
echo $dt->toDateString();               // 2015-12-19
echo $dt->toTimeString();               // 10:10:16
echo $dt->toDateTimeString();           // 2015-12-19 10:10:16
