I need to check the value of one of the fields in an array but I can not.

var_dump($array_exemplo);

array(1) {
   [0]=>
   array(3) {
     ["primeiro"]=>
        string(1) "1"
     ["segundo"]=>
        string(1) "2"
     ["terceiro"]=>
        string(1) "3"
   }
}

var_dump($array_exemplo["segundo"]);

You have an array inside another so you can not pretend you do not have this array .

$array_exemplo = array(
    0 => array(
        "primeiro" => "1",
        "segundo" => "2",
        "terceiro" => "3"
    )
);
var_dump($array_exemplo);
var_dump($array_exemplo[0]);
var_dump($array_exemplo[0]["segundo"]);
