Php 从繁忙时间数组中获取可用时间
我有一个php的预定时间数组，如下所示：Php 从繁忙时间数组中获取可用时间,php,laravel,Php,Laravel,我有一个php的预定时间数组，如下所示： 打印（$data） 现在，我想找到每天可用时间的详细信息。 为了检查这一点，让我们考虑营业时间是从 07:00 00 < /代码>到代码> 20:00时> /p> 现在，我想通过过滤上述所有预定时间来查找这些小时之间的可用时间，即07:00:00到20:00:00 $available_hour = => Array( [2019-09-26] => Array( [

外汇（$x为$value）
{
如果（数组键存在（$value['start\u date'，$res））
{
end（$res[$value['start_date']]）；//将内部指针移动到数组的末尾
$key=key（$res[$value['start_date']]）；

}
如果（！empty（$res[$value['start_date'][$key]['start']））
{
如果（$value['end_time']>='07:00:00'&&$value['end_time']]$value['end_time']；
}
}
}
其他的
{
如果（$value['start\u date']>='07:00:00'&&$value['start\u date']]“07:00:00”，'end'=>$value['start\u time']；
结束（$res[$value['start_date']]）；
$key=key（$res[$value['start_date']]）；
$res[$value['start\u date'][++$key]=['start'=>$value['end\u time']]；
}
}
}
foreach（$res作为$key=>$result）
{
foreach（$k=>v的结果）
{
如果（！array_key_存在（'end'，$v））
{
未设置（$result[$k]）；
}
}
$new[$key]=$result；
}
最后的结果将是

id107:00:0020:00:00startend使用数组function@Usira你能帮我写代码吗？不需要这个函数，只需在数组中循环并创建新的数组就行了。这不起作用，而且没有提到业务周期意味着开始时间是07:00:00和20:00:00。只需更改第一个预定时段的开始时间（2019-09-26）例如，您可以查看此链接，而不是07:00:00至08:00:00，您的代码将失败。您可以告诉我您在哪里包含了营业时间，即上午7点至晚上8点。请检查此代码，我已将第一个开始时间更新为上午8点，然后为什么它仍然显示9-12点的可用时间，而不是显示上午7点至上午8点的可用时间我想你需要把循环时间限制在早上7点到晚上8点之间，而不是从第一个数组元素开始计时啊，是的，你也需要先排序时间，对吗？我想你对这个问题不是很了解。所有数组都是预定的时间。这意味着2019-09-26一个大厅（假设上午7点开门，晚上8点关门）从上述时间开始预订。表示该大厅已预订7-9、12-14、16-17和19-20。这表示该大厅仍可预订9-12、14-16和17-19。但是，如果该大厅已预订8-9、12-14、16-17和19-20，则您的代码在本例中无法在此检查。当此时间仍然为0时，您的结果中不会显示7-8我有空，因为大厅早上7点开门
