Php 如果长度小于，则取消设置数组元素

我有以下数组：

Array
(
    [1] => Array
        (
            [team1_id] => 2
            [agegroup_id] => 18
            [team2_id] => 3
            [team_ground] => Adeilade
            [matchdate] => 2016-04-01
            [matchtime] => 9:00 AM
        )

    [2] => Array
        (
            [team1_id] => 3
            [agegroup_id] => 18
            [team2_id] => 2
            [team_ground] => Adeilade
            [matchdate] => 2016-04-13
            [matchtime] => 10:00 AM
        )

    [3] => Array
        (
            [team1_id] => 2
            [agegroup_id] => 18
            [team2_id] => 3
            [team_ground] => Adeilade
            [matchdate] => 2016-04-20
            [matchtime] => 2:00 PM
        )

    [4] => Array
        (
            [team1_id] => 3
            [agegroup_id] => 18
            [team2_id] => 2
            [team_ground] => Adeilade
            [matchdate] => 04/07/2016
            [matchtime] => 5:00 PM
        )

    [6] => Array
        (
            [team1_id] => 9
            [agegroup_id] => 36
            [team2_id] => 4
            [team_ground] => Motera Stadium
            [matchdate] => 2016-04-13
            [matchtime] => 9:00 AM
        )

    [7] => Array
        (
            [team1_id] => 4
            [agegroup_id] => 36
            [team2_id] => 9
            [team_ground] => Motera Stadium
            [matchdate] => 2016-04-13
            [matchtime] => 5:00 PM
        )

    [9] => Array
        (
            [team1_id] => 1
            [agegroup_id] => 37
            [team2_id] => 8
            [team_ground] => Eden Garden
            [matchdate] => 2016-04-18
            [matchtime] => 7:00 PM
        )

    [10] => Array
        (
            [team1_id] => 8
            [agegroup_id] => 37
            [team2_id] => 1
            [team_ground] => Eden Garden
            [matchdate] => 2016-04-25
            [matchtime] => 8:00 PM
        )

    [11] => Array
        (
            [team1_id] => 1
            [agegroup_id] => 37
            [team2_id] => 8
            [team_ground] => Eden Garden
            [matchdate] => 04/26/2016
            [matchtime] => 8:00 PM
        )

    [0] => Array
        (
            [agegroup_id] => 18
        )

    [5] => Array
        (
            [agegroup_id] => 36
        )

    [8] => Array
        (
            [agegroup_id] => 37
        )

)

若数组只有一个元素，那个么我必须取消设置它。在本例中，我想在PHP中取消设置数组索引0,5,8。当数组的元素较少时，如何取消设置数组索引？

您只需使用此处的数组过滤器即可

$result = array_filter($your_array,function($v){ return count($v) > 1;});
print_r($result);

您还可以使用简单的foreach：

foreach ($array as $key => $value)
  {
     if(sizeOf($array[$key]) < 2)
         unset($array[$key]);
  }

这是一张有效的
