我需要数组如下所示请帮帮我，

Array

    [2] => Array
    (
        [Date] => 2014-06-29
        [Tables] => Array
            (

                    )
                )

            )   
    )
)

我已使用以下代码在CODEIGNITER Framework中获取结果php，

我试过这样，

function example（）{

    $oldArray = $this->db->query("Select StartTime,EndTime,date(StartTime) as Date,BookingId,TableId from tblbooking")->result_array();



    foreach ($oldArray as $row){

        $data = $row['Date'];
        $newArray[$row['Date']][$row['TableId']][] = array('TableId' => $row['TableId'],'Date' => $row['Date'],'BookingId' => $row['BookingId']);

    }

    foreach($newArray as $index => $back){

            foreach($back as $index2 => $back2){
                $t3[] = array( 'Date' => $index,'Tables' => $back);
            }
    }

    print_r($t3);
}

但是我无法获得上面的数组列表所以请帮帮我

未经测试，但有类似的事情。

首先，将数组排序为日期顺序，并将日期中的tableid顺序排序（您可以在获取数组数据的SQL查询中执行此操作）。

然后循环跟踪日期/表格的变化，设置日期/表格的计数器。

<?php

$Out = array();
$prev_date = '';
$prev_table = '';
$day = -1;
$table = -1;

// Sort the array into date order, and table order within date
usort($some_array, "cmp");

foreach($some_array AS $some_array_item)
{
    if ($some_array_item['Date'] != $prev_date)
    {
        $day++;
        $Out[$day] = array();
        $Out[$day]['Date'] = $some_array_item['Date'];
        $Out[$day]['Tables'] = array();
        $table = -1;
        $prev_date = $some_array_item['Date'];
        $prev_table = '';
    }
    if ($some_array_item['TableId'] != $prev_table)
    {
        $table++;
        $Out[$day]['Tables'][$table]['TableId'] = $some_array_item['TableId'];
        $Out[$day]['Tables'][$table]['Reservations'] = array();
        $prev_table = $some_array_item['TableId'];
    }
    $Out[$day]['Tables'][$table]['Reservations'][] = array('BookingId'=>$some_array_item['BookingId']);
}

function cmp($a, $b)
{
    if ($a['Date'] == $b['Date']) 
    {
        if ($a['Date']['TableId'] == $b['Date']['TableId']) 
        {
            return 0;
        }
        return ($a['Date']['TableId'] < $b['Date']['TableId']) ? -1 : 1;
    }
    return ($a['Date'] < $b['Date']) ? -1 : 1;
}

?>
