Php 是否可以使用数组_split按日期拆分数据库结果？

我不知道这能不能做到。我从数据库返回了1000多行，并希望在返回后使用array_split按日期对它们进行拆分。日期以unix时间戳的形式显示

我想做的是按日期分页这些结果。如果可以做到这一点，有人能给我举个小例子，或者给我指出我需要走的方向吗

您需要选择将格式从时间戳转换为日期字符串的新字段，并按其排序

循环遍历结果集，当日期与上一个值不同时，创建一个子数组

PHP代码和SQL（PS：您必须首先按“创建日期”进行订购）

PS:

groupby

函数并不能真正对整个数据集进行分组

$sql = " SELECT *, DATE_FORMAT(create_timestamp, '%Y-%m-%d') as create_date FROM some_table order by create_date asc";

$result = mysqli_query($dblink, $sql);

$grouped = group_by($result, 'create_date');


function group_by($inArray, $keyName) {
    if (is_array($inArray) && count($inArray)>0) {
        $cabinet = array();
        $tempBox = array();
        $prevoius_value = $inArray[0][$keyName];
        for($b=0;$b<count($inArray);$b++){
            $box = $inArray[$b];
            if ($prevoius_value != $box[$keyName]){
                array_push($cabinet, $tempBox);
                $tempBox = array();
                $prevoius_value = $box[$keyName];
            }
            array_push($tempBox, $box);
        }
         array_push($cabinet, $tempBox);
         return $cabinet;
    }
}

1.试着在DB端做。2.举例说明

$result = array(
    [0] => array(
        'id' => 1,
        'name' => 'One',
        'create_timestamp' => '123456789',
        'create_date' => '2014-04-02'
    ),

    [1] => array(
        'id' => 1,
        'name' => 'Two',
        'create_timestamp' => '123456789',
        'create_date' => '2014-04-03'
    ),

    [2] => array(
        'id' => 1,
        'name' => 'Three',
        'create_timestamp' => '123456789',
        'create_date' => '2014-04-03'
    ),

    [3] => array(
        'id' => 1,
        'name' => 'Four',
        'create_timestamp' => '123456789',
        'create_date' => '2014-04-04'
    ),
);

$grouped = array(
    [0] => array(
        [0] => array(
            'id' => 1,
            'name' => 'One',
            'create_timestamp' => '123456789',
            'create_date' => '2014-04-02'
        )
    ),

    [1] => array(
        [0] => array(
            'id' => 2,
            'name' => 'Two',
            'create_timestamp' => '123456789',
            'create_date' => '2014-04-03'
        ),

        [1] => array(
            'id' => 3,
            'name' => 'Three',
            'create_timestamp' => '123456789',
            'create_date' => '2014-04-03'
        )
    ),

    [2] => array(
        [0] => array(
            'id' => 4,
            'name' => 'Four',
            'create_timestamp' => '123456789',
            'create_date' => '2014-04-04'
        )
    ),
);
