Create associative array from 2 columns in PHP and MySQL

Question

Can I make an associative array from two columns? I want column A as key and column B as value.

-------------
| id | name  |
-------------
| 1  | sky   |
-------------
| 2  | space |

I want a function that make result like this:

$ary=array('1'=>'sky','2'=>'space', ... );

Is any php function exist about this matter?

I'm using php, mysql and codeigniter.

Answer 1

$ary = array();
while ($row = $stmt->fetch_assoc()) {
    $ary[$row['id']] = $row['name'];
}

Answer 2

Even though you are using codeigniter, you are not required to use codeigniter's libraries. If you are willing to implement a PDO implementation you can do something like this in native PHP:

$stmt = $db->query("select id, name from mytable");
$results  = $stmt->fetchAll(PDO::FETCH_KEY_PAIR);

There would be less overhead this way than with some other implementations, but it depends if you want to use PDO.

Answer 3

foreach($rows as $key => $value){
    $arr[$key] = $value;
}
