What’s wrong with that code?

Question

all right?

I am a beginner in PHP and I am "side" in a simple code, in which I have seen numerous answers here in the forum, and I did exactly as it is in the answers (until CTRL+C CTRL+V) and it doesn’t work.

Is the following:

I need to capture the content of a variable (for $_GET[]) and delete that content from the database.

The capture is perfect. Really it recognizes the content, stores in the variable and tals... (I did several tests and gave right). But what’s tying me up is that you can’t delete the comic book.

The Code is this:

    <?php 

require_once "dbconfigurator.php";

$id = $_GET['emaillead'];

if(isset($id)) {

    $apaga = "DELETE FROM leads WHERE codlead=" . $id;

    $apagando = mysqli_query($apaga) or die ('Erro ao Apagar Email');

    $fechando = mysqli_close($conexaobd);

    echo "<h1>Sentiremos sua falta!</h1><br><h3>O email " . $id . " foi excluido de nosso banco de dados!</h3>";
    } else {
        echo "Email não encontrado!";
        }



?>

I need to know where the error is because it finds the contents of the variable, but does not delete from the bank. The dbconfigurator.php file is correct, because the same is used in the capture.php file and the same makes the insertion in the database perfectly.

I stand by!!
