我正在比較 2 個(gè)數(shù)組，但在應(yīng)用 array_diff 后，它以對象形式返回結(jié)果?？纯聪旅娴拇a和結(jié)果<?php $schedule = ['Monday'=>['12:00','01:20'],'Tuesday'=>['04:00','12:00','20:00']]; $booked_slots = ['Monday'=>['12:00'],'Tuesday'=>['20:00']]; $diff = []; foreach ($schedule as $day => $times) { $day_wise_slots = isset($booked_slots[$day]) ? $booked_slots[$day] : []; $diff[$day] = array_diff($times, $day_wise_slots); } echo json_encode($diff);?>結(jié)果：{"星期一":{"1":"01:20"},"星期二":["04:00","12:00"]}所需輸出：{“星期一”：[“01:20”]，“星期二”：[“04:00”，“12:00”]}

array_diff保留原始數(shù)組的鍵。您需要重新初始化數(shù)組，以使 json 中沒有數(shù)組鍵。您可以使用array_values來獲取重新初始化的數(shù)組鍵
<?php
$schedule = ['Monday'=>['12:00','01:20'],'Tuesday'=>['04:00','12:00','20:00']];
$booked_slots = ['Monday'=>['12:00'],'Tuesday'=>['20:00']];
$diff = [];
foreach ($schedule as $day => $times) {
$day_wise_slots = isset($booked_slots[$day]) ? $booked_slots[$day] : [];
$diff[$day] = array_values(array_diff($times, $day_wise_slots));
}
echo json_encode($diff);
?>
