One solution I found to your problem is this:

You have array() of hours that have already been chosen as the query response through mysqli_fetch_array() , which in the example I set as $horas_cadastradas , in your case would be:

$horas_cadastradas = mysqli_fetch_array($query);

You have the total hours matrix, which in the example I set to $horas_totais .

Using the foreach() loop in the $horas_totais array and using the in_array() function to check if the time exists in the $horas_cadastradas array:

$horas_cadastradas = array("18:00","19:00","20:00");
$horas_totais = array("9:00","10:00","11:00","12:00","13:00","14:00","15:00","16:00","17:00","18:00","19:00","20:00","21:00","22:00","23:00");
foreach ($horas_totais as $hora) {
    if(in_array($hora,$horas_cadastradas)){
        echo '"Horário Indisponível"<br>';
    }else{
        echo $hora."<br>";
    }
}

We were able to get to the result of:

9:00
10:00
11:00
12:00
13:00
14:00
15:00
16:00
17:00
"Horário Indisponível"
"Horário Indisponível"
"Horário Indisponível"
21:00
22:00
23:00

♦ Function reference in_array ()

while creation array() :

while ($dados_do_mysql = mysqli_fetch_array($query)){
    $horas_cadastradas[]=$dados_do_mysql['hora'];
}
