I have a problem to understand why this doesn't work. I have recursive function who check if value in multidimensional array exists.
Then I have `get_teams()` function from which I want to return only unique values. I check for unique values with my `find_value()` function but it still return all the values.. Can someone explain me what happens? Thanks in advance

```
function find_value( $array, $searched_val ) {
    foreach ( $array as $key => $val ) {
        if ( $val === $searched_val ) {
            return true;
        }

        if ( is_array( $val ) ) {
            return find_value( $val, $searched_val );
        }
    }
    return 0;
}

get_teams();

function get_teams() {
    $people = get_data( 'some/file.json' );
    $teams = [];

    foreach ( $people as $person ) {
        if (  ! find_value( $teams, $person['team'] ) ) {
            $teams[] = [ 'text' => $person['team'] ];
        }
    }
    return $teams;
}

```

This is sample input

```
Array
(
[0] => Array
    (
        [id] => 1
        [name] => Friedrich Robel
        [team] => WordPress
        [position] => Frontend Developer
        [salary] => 4400
    )

[1] => Array
    (
        [id] => 2
        [name] => Mr. Christop Veum
        [team] => HTML
        [position] => Manager
        [salary] => 1200
    )

[2] => Array
    (
        [id] => 3
        [name] => Demarco Rippin
        [team] => HTML
        [position] => QA
        [salary] => 4400
    )

[3] => Array
    (
        [id] => 4
        [name] => Felicia Farrell
        [team] => HTML
        [position] => QA
        [salary] => 1200
    )

[4] => Array
    (
        [id] => 5
        [name] => Torrance Fritsch
        [team] => HTML
        [position] => Assistant Manager
        [salary] => 2500
    )

[5] => Array
    (
        [id] => 6
        [name] => Erica Daugherty
        [team] => Mail
        [position] => Assistant Manager
        [salary] => 500
    )
)

```

And I want this output 

```
 Array
(
[0] => WordPress,
[1] => HTML,
[2] => Mail
)

```
