fetch data primary key value as the index for the associative array

Question

After executing a fetch query I get a result array:

[row_choice] => Array
  (
    [0] => Array
      (
        [id] => 277410
        [text_value] =         


        

Answer 1

You should create a new array variable as below.

$recArr = array();

while ($records = mysqli_fetch_array($query)) {
    $recArr[$records['id']] = $records;
}

var_dump($recArr);

Good luck.

Answer 2

It isn't possible directly from the SQL query: but you can retrieve all your data, then re-map the array

Using PHP 5.5's array_column() you can do something like:

$myarray['row_choice'] = array_combine(
    array_column($myarray['row_choice'], 'id'),
    $myarray['row_choice']
);

else for earlier versions of PHP, use array_map() instead

$myarray['row_choice'] = array_combine(
    array_map(
        function($value) {
            return $value['id'];
        },
        $myarray['row_choice']
    ),
    $myarray['row_choice']
);
