Question

how get each single column data from php multidimensional into single column array?

like $_test = = array(
    array(
        'id' => 1001,
        'first_name' => 'kalpesh',
        'last_name' => 'gamit',
    ),
    array(
        'id' => 1002,
        'first_name' => 'kartik',
        'last_name' => 'patel',
    ),
    array(
        'id' => 2002,
        'first_name' => 'smith',
        'last_name' => 'Jones',
    ),
    array(
        'id' => 4004,
        'first_name' => 'patel',
        'last_name' => 'Doe',
    )
);

want result like id OR first_name only without use loop like while, foreach, for etc

Array
(
    [0] => 1001
    [1] => 1002
    [2] => 2002
    [3] => 4004
)

update your script like below and check it please but it will work only in PHP 5.5 greater than version only...

 $_test = = array(
    array(
        'id' => 1001,
        'first_name' => 'kalpesh',
        'last_name' => 'gamit',
    ),
    array(
        'id' => 1002,
        'first_name' => 'kartik',
        'last_name' => 'patel',
    ),
    array(
        'id' => 2002,
        'first_name' => 'smith',
        'last_name' => 'Jones',
    ),
    array(
        'id' => 4004,
        'first_name' => 'patel',
        'last_name' => 'Doe',
    )
);

$ids_only = array_column($records, 'id');
print_r($ids_only);

Results for ID

Array
(
    [0] => 1001
    [1] => 1002
    [2] => 2002
    [3] => 4004
)

Results for first_name

$first_name = array_column($records, 'id');
print_r($first_name);
Array
(
    [0] => Kalpesh
    [1] => kartik
    [2] => smith
    [3] => patel
)

run above php script and please check....

You could use array_map:

$id_list = array_map(function($var) {
  return $var['id'];
}, $_test);
