Question

我在下面的查询中使用了ID为键值的数组结果，

$this->db->select('gp.id, gp.lot_no, SUM(gb.weight) AS weight, SUM(gb.staple) AS staple, SUM(gb.mic) AS mic, SUM(gb.strength) AS strength, SUM(gb.trash) AS trash, gb.color_grade');
            $this->db->from(GIN_BALES . ' gb');
            $this->db->join(GIN_PROCESS . ' gp', 'gp.id=gb.process_id'); 
            $this->db->where('gb.sold_status', 0);
            $this->db->where('gp.ginner_id', $this->prscr_id);
            $this->db->where('gp.program', $program_id);
            $this->db->group_by('gp.id');
            $lot_details = $this->db->get()->result();

但是我得到如下数组结果，并且数组键的值为0.1。我想要ID为561,562的数组键。

Array
(
    [0] => stdClass Object
        (
            [id] => 561
            [lot_no] => 1
            [weight] => 16230
            [staple] => 3600
            [mic] => 0
            [strength] => 0
            [trash] => 0
            [color_grade] => 0
        )

    [1] => stdClass Object
        (
            [id] => 562
            [lot_no] => 2
            [weight] => 15523
            [staple] => 3600
            [mic] => 0
            [strength] => 0
            [trash] => 0
            [color_grade] => 0
        )
)

任何人都可以为该查询问题提供解决方案吗？

Answer 1

这是一支班轮，

// null will take id as key and whole array as value
$temp = array_column($temp, null, "id");

参考：array_column。

Demo。

输出：

Array
(
    [561] => stdClass Object
        (
            [id] => 561
            [lot_no] => 1
            [weight] => 16230
            [staple] => 3600
            [mic] => 0
            [strength] => 0
            [trash] => 0
            [color_grade] => 0
        )

    [562] => stdClass Object
        (
            [id] => 562
            [lot_no] => 2
            [weight] => 15523
            [staple] => 3600
            [mic] => 0
            [strength] => 0
            [trash] => 0
            [color_grade] => 0
        )

)

您还可以通过使用ID index将结果存储到新数组中来获得所需的结果，例如：

<?php
$lot_details = $this->db->get()->result(); // your result
$newArray = array(); // initialize
foreach ($lot_details as $key => $value) {
    $newArray[$value->id] = $value; // store in a new array
}
print_r($newArray);
?>

获取键值为id而不是数组键为0,1的数组结果
