问题描述
Ex->
Start time = 2015-10-21 09:00:00
end time = 2015-10-21 19:45:00
根据我的示例-开始时间为上午9点到晚上7-45pm
so as per my example - start time is 9 am to 7-45pm
所以我希望有20分钟的时段。在PHP中，例如
so i want possible slot of 20 min. in php like
9:00-9:20，9-20至9-40等。而且还预订了 ex 12：00-12：20，2:40至2:60 ，则该价格将不包含在此列表中。
9:00 - 9:20 , 9-20 to 9-40 etc. but also for ex 12:00-12:20 , 2:40 to 2:60 booked then it will not included in this list.
我想腾出20分钟的时间。是的，但是它还会过滤alr
I want to make 20 min slot. yes but it will also filter alr
使用php中的时差，我有开始时间和结束时间。
Using the time difference in php i have start time and end time.
然后我要检查从开始时间到结束时间可能有20分钟的时间段
And then i want to check that how many 20 min slot possible from start and end time
=>
IN SHOT 1 to 2 or 3-5 is break time then it will not consider.
推荐答案
这将满足您的需求。但是，应为数组元素保留特定格式，以便于计算。
This will do what you need. But specific format should be kept for array elements, for easy calculations.
<?php
$start_time = '2015-10-21 09:00:00'; //start time as string
$end_time = '2015-10-21 19:45:00'; //end time as string
$booked = array('12:20-12:40','13:00-13:20'); //booked slots as arrays
$start = DateTime::createFromFormat('Y-m-d H:i:s',$start_time); //create date time objects
$end = DateTime::createFromFormat('Y-m-d H:i:s',$end_time); //create date time objects
$count = 0; //number of slots
$out = array(); //array of slots
for($i = $start; $i<$end;) //for loop
{
$avoid = false; //booked slot?
$time1 = $i->format('H:i'); //take hour and minute
$i->modify("+20 minutes"); //add 20 minutes
$time2 = $i->format('H:i'); //take hour and minute
$slot = $time1."-".$time2; //create a format 12:40-13:00 etc
for($k=0;$k<sizeof($booked);$k++) //if booked hour
{
if($booked[$k] == $slot) //check
$avoid = true; //yes. booked
}
if(!$avoid && $i<$end) //if not booked and less than end time
{
$count++; //add count
$slots = ['start'=>$time1, 'stop'=>$time2]; //add count
array_push($out,$slots); //add slot to array
}
}
var_dump($out); //array out
echo $count ." of slots available";
如果使用预订的日期时间作为数组，请使用以下代码。
If you use booked datetime as array, use below code.
<?php
$start_time = '2015-10-21 09:00:00'; //start time as string
$end_time = '2015-10-21 19:45:00'; //end time as string
$booked = ['2015-10-21 12:20:00','2015-10-21 12:40:00', '2015-10-21 13:00:00','2015-10-21 13:20:00'];
//booked slots as arrays
$start = DateTime::createFromFormat('Y-m-d H:i:s',$start_time); //create date time objects
$end = DateTime::createFromFormat('Y-m-d H:i:s',$end_time); //create date time objects
$time1 = $start;
$count = 0; //number of slots
$out = array(); //array of slots
for($i = $start; $i<$end;) //for loop
{
$avoid = false;
$t1 = date_timestamp_get($i);
$t2 = $t1+(20*60);
for($k=0;$k<sizeof($booked);$k+=2) //if booked hour
{
$st = DateTime::createFromFormat('Y-m-d H:i:s',$booked[$k]);
$en = DateTime::createFromFormat('Y-m-d H:i:s',$booked[$k+1]);
if( $t1 >= date_timestamp_get($st) && $t2 <= date_timestamp_get($en) )
$avoid = true; //yes. booked
}
$slots =[ $i->format('H:i'),$i->modify("+20 minutes")->format('H:i')];
if(!$avoid && $i<$end) //if not booked and less than end time
{
$count++;
array_push($out,$slots); //add slot to array
}
}
var_dump($out); //array out
echo $count ." of slots available";
