我正在寻找一些关于找到最接近的startTime(推荐的startTime)的最佳方法的建议。
到目前为止我得到了什么:
<?php
$array = array( array("meeting_id" => "1812",
"startTime" => "2016-10-07 14:30:00",
"endTime" => "2016-10-07 14:35:00"),
array("meeting_id" => "1812",
"startTime" => "2016-10-07 14:35:00",
"endTime" => "2016-10-07 14:40:00"),
array("meeting_id" => "1812",
"startTime" => "2016-10-07 14:40:00",
"endTime" => "2016-10-07 14:45:00"),
array("meeting_id" => "1813",
"startTime" => "2016-10-07 15:05:00",
"endTime" => "2016-10-07 15:10:00"),
array("meeting_id" => "1813",
"startTime" => "2016-10-07 15:10:00",
"endTime" => "2016-10-07 15:15:00"),
array("meeting_id" => "1813",
"startTime" => "2016-10-07 15:20:00",
"endTime" => "2016-10-07 15:25:00"),
);
arsort($array);
$firstTime = $array[0];
foreach($array as $key){
if($firstTime["startTime"] > $key["endTime"]){
// Do something in here.
}
}
print_r($array);
?>
印刷阵列:
Array
(
[5] => Array
(
[meeting_id] => 1813
[startTime] => 2016-10-07 15:20:00
[endTime] => 2016-10-07 15:25:00
)
[4] => Array
(
[meeting_id] => 1813
[startTime] => 2016-10-07 15:10:00
[endTime] => 2016-10-07 15:15:00
)
[3] => Array
(
[meeting_id] => 1813
[startTime] => 2016-10-07 15:05:00
[endTime] => 2016-10-07 15:10:00
)
[2] => Array
(
[meeting_id] => 1812
[startTime] => 2016-10-07 14:40:00
[endTime] => 2016-10-07 14:45:00
)
[1] => Array
(
[meeting_id] => 1812
[startTime] => 2016-10-07 14:35:00
[endTime] => 2016-10-07 14:40:00
)
[0] => Array
(
[meeting_id] => 1812
[startTime] => 2016-10-07 14:30:00
[endTime] => 2016-10-07 14:35:00
)
)
我希望它如何运作:

以下函数将您的数组作为第一个参数,会议ID作为第二个参数,然后将最近的会议返回到ID不是$id
的最早会议:
function get_nearest_meeting($meetings, $id)
{
// Start by sorting the meetings:
function sorter($a, $b)
{
return strtotime($a['startTime']) - strtotime($b['startTime']);
}
usort($meetings, 'sorter');
foreach( $meetings as $meeting )
{
if( $meeting['meeting_id'] == $id)
{
$earliest = strtotime( $meeting['endTime'] );
break;
}
}
// Now loop over again and get the next meeting:
foreach( $meetings as $meeting )
{
if( $meeting['meeting_id'] != $id && strtotime($meeting['startTime']) > $earliest)
{
return $meeting;
}
}
}
给出以下输入(存储在$meetings
中):
Array
(
[0] => Array
(
[errors] => 0
[meeting_id] => 1812
[id] => 31305
[startTime] => 2016-10-07 14:00:00
[endTime] => 2016-10-07 14:10:00
[grade_id] => 87
)
[1] => Array
(
[errors] => 0
[meeting_id] => 1813
[id] => 31305
[startTime] => 2016-10-07 14:10:00
[endTime] => 2016-10-07 14:20:00

)
[2] => Array

[endTime] => 2016-10-07 14:30:00
[grade_id] => 87
)
[4] => Array
(
[errors] => 0
[meeting_id] => 1813
[id] => 31305
[startTime] => 2016-10-07 14:20:00
[endTime] => 2016-10-07 14:30:00
[grade_id] => 87
)
[5] => Array
(

[startTime] => 2016-10-07 14:30:00
[endTime] => 2016-10-07 14:40:00
[grade_id] => 87
)
[6] => Array
(
[errors] => 0
[meeting_id] => 1812
[id] => 31305
[startTime] => 2016-10-07 14:30:00
[endTime] => 2016-10-07 14:40:00
[grade_id] => 87
)
[7] => Array
(
[errors] => 0
[meeting_id] => 1813
[id] => 31305
[startTime] => 2016-10-07 14:30:00
[endTime] => 2016-10-07 14:40:00
[grade_id] => 87
)
[8] => Array
(
[errors] => 0
[meeting_id] => 1815
[id] => 31305
[startTime] => 2016-10-07 14:40:00
[endTime] => 2016-10-07 14:50:00
[grade_id] => 87
)
[9] => Array
(
[errors] => 0
[meeting_id] => 1813
[id] => 31305
[startTime] => 2016-10-07 14:40:00
[endTime] => 2016-10-07 14:50:00
[grade_id] => 87
)
)
并且这样称呼它:
get_nearest_meeting($meetings, 1812);
我们最终得到以下结果:
Array
(
[errors] => 0
[meeting_id] => 1813
[id] => 31305
[startTime] => 2016-10-07 14:10:00
[endTime] => 2016-10-07 14:20:00
[grade_id] => 87
)
