How do I upload php file correctly when it has special characters or accents?

Question

Hello, I am trying to upload an audio file in php, the problem is that the file should be moved to a name with accentuation, til, for example. Example: Save the file named Sebastião.mp3, but php at the time of moving the file upload moves with the name of Sebastiã£o.mp3

look at the upload.php file

$target_dir = "../../mp3/";
$nomeF="Sebastião"; <- aqui eu pego no banco de dados o nome...
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$target_file2=utf8_encode($target_dir).$nomeF.utf8_encode(".mp3"); <- tentei codificar o arquivo mas nao deu resultado
ou
$target_file2=$target_dir.$nomeF.".mp3";
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
if ($_FILES["fileToUpload"]["size"] > 59900000) {
        $uploadOk = 0;
    }
    // Allow certain file formats
    if($imageFileType != "mp3" ) {
        $uploadOk = 0;
    }
    // Check if $uploadOk is set to 0 by an error
    if ($uploadOk == 0) {

    } else {
        if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file2)) {

        } else {

        }
    }

However, as I said, the file saved wrong. Someone knows what to do?

Answer 1

An interesting approach is to create a hash using MD5 to be the file name in your directory and save it in the database linking to the real name (with accents and special characters)

echo md5('apple');
//1f3870be274f6c49b3e31a0c6728957f

I see as a safe and organized way.
