[英]Get spesified column from result_array in codeigniter
I'm about using CodeIgniter for my first project. 我打算在第一个项目中使用CodeIgniter。 I have tried to get data from database.
我试图从数据库中获取数据。
$test = $this->komponen_model->get_participants_id()->result_array();
print_r($test)
Array (
[0] => Array ( [id] => 1 )
[1] => Array ( [id] => 4 )
[2] => Array ( [id] => 7 )
)
And I got this. 我知道了。 So, I need to call each element by:
因此,我需要通过以下方式调用每个元素:
foreach ($test as $ts){
echo $ts['id'];
}
My question is, can I make the array shorten. 我的问题是,我可以使数组缩短吗? Just like:
就像:
Array (
[0] => 1
[1] => 4
[2] => 7
)
I will be appreciated for anyone's advise. 如有任何建议,我将不胜感激。
Use array_column
使用
array_column
$test = array_column($test,'id');
foreach ($test as $ts){
echo $ts;
}
