usort($value['year'], function ($a, $b) { if ($a->date == $b->date) return 0; return $a->date < $b->date ? -1 : 1; }); usort($value['year'], function ($a, $b) { if ($a->month == $b->month) return 0; return $a->month < $b->month ? -1 : 1; });
the following code job. strtotime parses text date unix timestamp.
usort($array, function($v1, $v2) { $d1 = strlen($v1->manudate) === 4 ? '01-01-' . $v1->manudate : $v1->manudate; $d2 = strlen($v2->manudate) === 4 ? '01-01-' . $v2->manudate : $v2->manudate; return strtotime($d1) - strtotime($d2); });
