如何分割的基础上一定值的阵列？ [英] How to split an array based on a certain value?

问题描述

我现在有相似的下面基于位置的信息（这是已经按时间排序）的阵列。第一个键/值事件，重新presents的旅程的开始（00），正在运行的旅程（01）的旅程（10）的结束。

I currently have an array of location based information similar to below (which is already sorted by time). The first key/value is event which represents the start of a journey (00), a running journey (01) and an end of a journey (10).

Array ( 
[0] => Array ( [event] => 00 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[1] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[2] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[3] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[4] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[5] => Array ( [event] => 10 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[6] => Array ( [event] => 00 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[7] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[8] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[9] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[10] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[11] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[12] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[13] => Array ( [event] => 10 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[14] => Array ( [event] => 00 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[15] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[16] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[17] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[18] => Array ( [event] => 10 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
)

我怎样才能在阵列进一步分裂，因此创造了每一段旅程一个新的数组，所以我会这样结束了：

How can I split the array even further so it creates a new array for every journey so I would end up with this:

Array (
[0] => Array (
[0] => Array ( [event] => 00 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[1] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[2] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[3] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[4] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[5] => Array ( [event] => 10 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
)
[1] => Array (
[0] => Array ( [event] => 00 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[1] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[2] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[3] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[4] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[5] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[6] => Array ( [event] => 01 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
[7] => Array ( [event] => 10 [time] => 1329293878 [lat] => 66.66666 [lon] => 11.11111 )
)
...
)

我还没有尝试任何事情（除了谷歌搜索），因为我真的不知道从哪里开始。

I haven't tried anything yet (except for googling) as I don't really know where to start.

推荐答案

您需要自定义，像这样的解决方案：

you need a custom solution like so:

 $outputArray = array(); $currentArray = array();
 foreach($inputArray as $key=>$subArray) {
   if($subArray['event']==00) {
      $outputArray[] = $currentArray;
      $currentArray = array($subArray);
   } else {
      $currentArray[] = $subArray;
   }
 }
 $outputArray[] = $currentArray;
 array_shift($outputArray);

放在$ inputArray然后全身而退$ outputArray。尽情享受吧！

put in $inputArray and then get out $outputArray. Enjoy!
