php - 无法在 codeigniter View 中显示逗号分隔值

Question

我有这个数组我没有得到 area_tutor 因为它有带逗号的值

Array
(
    [0] => stdClass Object
        (
            [tuitor_id] => 288
            [mobile_tuitor] => 0123456789
            [alt_mobile_tuitor] => 
            [fullname_tuitor] => 
            [gender_tuitor] => male
            [city_tutor] => 2
            [area_tutor] => 7,8,9
        )

    [1] => stdClass Object
        (
            [tuitor_id] => 287
            [mobile_tuitor] => 2568798456
            [alt_mobile_tuitor] => 
            [fullname_tuitor] => sumit test new filed
            [gender_tuitor] => male
            [city_tutor] => 1
            [area_tutor] => 3
        )

    [2] => stdClass Object
        (
            [tuitor_id] => 285
            [mobile_tuitor] => 1452587658
            [alt_mobile_tuitor] => 0789578469
            [fullname_tuitor] => Sumit Nair
            [gender_tuitor] => male
            [city_tutor] => 1
            [area_tutor] => 1,2,3,4
        )

    [3] => stdClass Object
        (
            [tuitor_id] => 273
            [mobile_tuitor] => 0954652478
            [alt_mobile_tuitor] => 
            [fullname_tuitor] => vbvbbb
            [gender_tuitor] => female
            [city_tutor] => 1
            [area_tutor] => 3
        )

    [4] => stdClass Object
        (
            [tuitor_id] => 225
            [profile_title] => 
            [mobile_tuitor] => 4557821212
            [alt_mobile_tuitor] => 5445587112
            [fullname_tuitor] => xyz
            [gender_tuitor] => male
            [city_tutor] => 4
            [area_tutor] => 14
        )

)

其中 area_tutor 有带逗号的值，我在从 foeach 循环中检索时没有得到我只得到 area_tutor 的第一个元素，这就是我用 foreach 循环循环的方式

$this->db->select('*')->from('tuitor');
$this->db->order_by("tuitor_id", "desc");
$this->db->join('city_tuitor', 'tuitor.city_tutor = city_tuitor.city_id', 'left');
$this->db->join('area_tuitor', 'tuitor.area_tutor = area_tuitor.area_id', 'left');

$query=$this->db->get();
return $result = $query->result();

现在看来我只是循环遍历 foreach 循环

如果我像这样打印我得到我得到上面的数组 打印_r($结果)；

但是当我当时试图回显值时，我只得到 area_tutor 的第一个值

 <?php  foreach($result as $r) { ?>
    echo $r->tuitor_id; 
    echo $r->mobile_tuitor;
    echo $r->city_tutor;
    echo $r->area_tutor;
    <?php } ?>

请帮助我如何获取 area_tutor 的所有值

尝试打印值的简单方法..

<?php 
$result = $query->result_array();
foreach($result as $key=>$val)
{
    echo $val['tuitor_id'];
    echo $val['mobile_tuitor'];
    echo $val['city_tutor'];
    echo $val['area_tutor'];
}
?>
