Question

I have table like this:

random_num
----------
0
15
12
...

and I have query SELECT random_num FROM table_name;.

I want to fetch array in way like:

$row[0] = 0;
$row[1] = 15;
$row[2] = 12;
etc..

But PHP lets me only to fetch it in this way:

$row[0]['random_num'] = 0;
etc..

How to fetch it as I want?

Answer 1

You can use array_map

//PHP >= 5.3 
$row = array_map(function($n) {
   return $row['random_num'];
}, $row);

//PHP < 5.3
function map($n) {
  return $n['random_num'];
}

$row = array_map('map', $row);


//EDIT
$row = array_map('implode', $row) //thanks to hakre
