如何在笨

Question

返回查詢結果作爲一個數組我有表（TAG）.. 我想選擇在此表中的所有標籤，並返回它作爲一個數組，其中TAG_ID =指數 和TAG_NAME =值 這樣的陣列

array(
      3 => 'Hazel Grouse', 
      4 => 'Common Quail', 
      5 => 'Common Pheasant', 
      6 => 'Northern Shoveler', 
      7 => 'Greylag Goose', 
      8 => 'Barnacle Goose', 
      9 => 'Lesser Spotted Woodpecker', 
      10 => 'Eurasian Pygmy-Owl', 
      11 => 'Dunlin', 
      13 => 'Black Scoter', 
) 

標籤返回這樣多d陣列

Array 
(
    [0] => Array 
     (
      [tag_id] => 3 
      [tag_name] => Hazel Grouse 
     ) 

    [1] => Array 
     (
      [tag_id] => 4 
      [tag_name] => Common Quail 
     ) 

這是查詢代碼

function get_alltags() { 
     $this->db->select('tag_id'); 
     $this->db->select('tag_name'); 
     $result = $this->db->get('d_tag'); 
    return $result->result_array(); 
    } 
    $alltags = $this->tag->get_alltags(); 
     echo "<pre>"; 
     print_r($alltags); 
     echo "</pre>"; 
     exit; 

Answer 1

你可以這樣做

$result=array(); 
$alltags = $this->tag->get_alltags(); 
foreach($alltags as $k => $v){ 
$result[$v['tag_id']]=$v['tag_name'];} 
echo "<pre>"; 
print_r($result);
