这个条件意味着什么？

Question

I'm studying a condition and I don't understand because one of the conditionals is set to true by default, without setting a variable before, does anyone tell me what this means?

$pagina= Pagina::findOrFail($datos->idpagina);
switch ($datos->tipodato)
{
    case 'logo':
    if(true)  //??
    {
        $datos->logo = urldecode($datos->logo);
        $datos->logo = str_replace(' ', '+', $datos->logo);
        $datos->logo = str_replace("data:image/png;base64,","",$datos->logo);
        $datos->logo = str_replace("data:image/jpg;base64,","",$datos->logo);
        $datos->logo = str_replace("data:image/jpeg;base64,","",$datos->logo);
        $pagina->logo =$datos->logo;
    }
    else
    {
        $pagina->logo =$datos->logo;
    }


    $nombreimagen="img".$datos->idpagina.".png";
    file_put_contents(public_path()."/imagenes/{$nombreimagen}",
        base64_decode($datos->logo));
    $pagina->archivologo=$nombreimagen;

    break;

It means that the code inside the if-statement always be executed and the code inside the else-block will never be.

A common reason is that it once was a condition based on a variable, but a programmer has inactivated it, but kept the else statement to make it easier to restore.
