Display array values only

I am a beginner in PHP and I am currently studying the arrays, and I have a silly question.

When I print my arrays, it comes this way

Array (
  [0] => Array ( [0] => 10 )
  [1] => Array ( [0] => 20 )
  [2] => Array ( [0] => 30 )
  [3] => Array ( [0] => 40 )
  [4] => Array ( [0] => 50 )
)

My interest is that only the numbers are displayed.

10, 20, 30, 40 50

Php code

while (($linha = fgetcsv($file)) !== FALSE)
{

  $carros[] = $linha;
  //print_r($linha);

}

fclose($file);
print_r($carros);

All help will be welcome

    Where does this array come from? Your question is very confusing.

Well, based only on the Array you showed in the question, to display only the values you can use for or foreach:

$arr = Array (
    0 => Array ( 0 => 10 ),
    1 => Array ( 0 => 20 ),
    2 => Array ( 0 => 30 ),
    3 => Array ( 0 => 40 ),
    4 => Array ( 0 => 50 )
);
foreach($arr as $value){
    echo $value[0]. " ";
}

Use the php native function 

array_values($array);
