获取 CodeIgniter ActiveRecord 结果中每一行的关联数组

Question

In CodeIgniter there is a function query->row_array which will give you an associative array of your result, mapping column names to values. However this function only works if there is a single row as a result.

What I need is a function which will return an associative array for each row in the query result.

I am currently doing:

$arr = array ();
foreach ($query->result() as $row) {
  array_push ($arr, array("col1" => $row->col1, "col2" => $row->col2, ...));
}
return $arr;

Not only is this annoying to read and write, but it also doesn't scale as I add more columns to this table. I have similar code in several places, and I wish I could replace it with something that is cleaner.

I was hoping for something like:

$arr = array ();
foreach ($query->result() as $row) {
  array_push ($arr, $row->to_array());
}
return $arr;

Is there something like that? Or even better:

return $query->result_array ();

Answer 1

Try

$query = $this->db->query("YOUR QUERY");

foreach ($query->result_array() as $row)
{
   echo $row['title'];
   echo $row['name'];
   echo $row['body'];
}

Answer 2

Use this method,

$query = $this->db->get_where('table', array('table_id' => $id));

        $queryArr = $query->result();        

        foreach ($queryArr[0] as $key=>$val)
        {
            $row[$key]=$val;
        }

print_r($row); //$row will give associative array

Answer 3

you can use result_array() see the original documentation http://ellislab.com/codeigniter/user-guide/database/results.html

Sample code.

$query = $this->db->query("YOUR QUERY");foreach ($query->result_array() as $row){ echo $row['title'];   echo $row['name'];   echo $row['body'];}

Answer 4

$this->db->row();

or

$query->row();
