How I can in laravel map function continue loop?

I have code:

return collect($response->rows ?? [])->map(function (array $userRow) {
        if ($userRow[0] == 'Returning Visitor') {
            return [
                $userRow[1] => [
                    'type' => $userRow[0],
                    'sessions' => (int) $userRow[2],
                ]
            ];
        } else {
            return false;
        }
});

And output:

Collection {#986 ▼
   #items: array:4 [▼
     0 => false
     1 => false
     2 => array:1 [▶]
     3 => array:1 [▶]
    ]
}

I don't need params with false, I need continue it or delete. How I can resolve this?

You can add a reject function after the map to remove all values that are false.

return collect($response->rows ?? [])
    ->map(function (array $userRow) {
        if ($userRow[0] == 'Returning Visitor') {
            return [
                $userRow[1] => [
                    'type' => $userRow[0],
                    'sessions' => (int) $userRow[2],
                ]
            ];
        } else {
            return false;
        }
    })
    ->reject(function ($value) {
        return $value === false;
    });

You can use filter() or reject() (inverse of filter) to filter your collection, then map as you need. Something like this:

return collect($response->rows ?? [])->filter(function (array $userRow) {
    return $userRow[0] == 'Returning Visitor';
})->map(function (array $userRow) {
    return [
        $userRow[1] => [
            'type'     => $userRow[0],
            'sessions' => (int) $userRow[2],
        ]
    ];
});
