The following code that I present to you right below is to upload a file ". CSV" and send the data to Mysql, but the post method is not sending anything to the function . PHP, and I get the message "empty".

<!DOCTYPE html>

Upload Stock

<form action="" method="POST" enctype="multipart/form-data">
    <div align="center">
        <p>Upload CSV: <input type="file" name="file"></p>
        <p><input type="submit" name="submit" value="Importar"></p>
    </div>

</form>

<?php
    include "APIConnecting.php";

    if (isset($_POST["submit"])) {
        if ($_FILES['file']['name']) {
            $arquivo = explode(";", $_FILES['file']['name']);
            if ($arquivo[1] == "csv") {
                $handle = fopen($_FILES['file']['tmp_name'], "r");
                while ($dados = fgetcsv($handle, 50)){
                    $item1 = mysqli_real_escape_string($con, $dados[0]);
                    $item2 = mysqli_real_escape_string($con, $dados[1]);
                    $sql = "INSERT INTO estoque (Chassi, Navio) VALUES ('$item1', '$item2')";
                    mysqli_query($con, $sql);
                }
                fclose($handle);
            }

        }
    }else{echo "vazio";}
?>

At line 4 where you check for the POST you could put the File field to ensure that it is sending a file.
In Line 6 you put ; (semicolon) the right one would . (point) to catch extension.

Changing only that, I tested it here and it worked. The Code went like this:

if (isset($_FILES['file'])) { 
    if ($_FILES['file']['name']) {
        $arquivo = explode(".", $_FILES['file']['name']);
        if ($arquivo[1] == "csv") {
            $handle = fopen($_FILES['file']['tmp_name'], "r");
            while ($dados = fgetcsv($handle, 50)){
                $item1 = mysqli_real_escape_string($con, $dados[0]);
                $item2 = mysqli_real_escape_string($con, $dados[1]);
                $sql = "INSERT INTO estoque (Chassi, Navio) VALUES ('$item1', '$item2')";
                if(mysqli_query($con, $sql)){
                  echo "Salvo com Sucesso.";
                }
            }
            fclose($handle);
        }

    }
}else{echo "vazio";}
