Select prioritized and ordered by field

Question

Well I have a schedule schedule table and I need to display the announcer who is live at the moment, I’m picking up via php the dates and playing in select but several times leaves or disorderly or does not leave for sure I will try to summarize what I have to facilitate. Remembering that you can have the same schedule on different days, so ORDER BY FIELD will give priority to $today.

 <?php
 $diasemana = array('Domingo', 'Segunda', 'Terca', 'Quarta', 'Quinta', 'Sexta', 'Sabado');
 $data = date('Y-m-d');
 $diasemana_numero = date('w', strtotime($data));
 $hoje = $diasemana[$diasemana_numero];

 $hora = date("H");
 $minuto = date("i");
 $horaatual = $hora."h".$minuto;
 try {
    $sql = "SELECT * FROM programacao WHERE horafinal >= '$horaatual' ORDER BY FIELD(dias,'$hoje','De Segunda a Sexta','De Segunda a Sabado'), horafinal ASC LIMIT 1";

I don’t know if this in logic or programming even the error, if anyone has any better idea also accept suggestions.
