Radio schedule php - php

Question

I am making a radio scheduler. It should show which program is on now.
<?php header('Access-Control-Allow-Origin: *'); ?>

$query = "SELECT time_end FROM shows WHERE day='$day' AND time_start='$hour'";
$result = mysql_query($query);
$query = "SELECT * FROM shows WHERE day='$day' AND time_start='$hour'";
$result = mysql_query($query);
if (mysql_num_rows($result)==0) {

Obviously, it shows shows that exactly last one hour. But now I have shows that start at 12 and end at 16. I don't know where to start or how to do it. How can I get the script to show a radio show between 12 and 16? I have the beginning and end time in the table als time_start and time_stop.

Answer 1

Try changing your second SQL line to this:
$query = "SELECT * FROM Shows WHERE day='$day' AND time_start<=$hour AND time_stop>$hour";
$result = mysql_query($query);
You can completely remove the first SQL query and keep all the other code the same. It uses SQL comparison operators that will return the radio show if the current hour is between the start and end hours. Using your example (12-16 hours), 12:15 and 15:50 would return the show, but 11:55 and 16:05 would not.
Edit: Please ensure that time_start and time_stop are SQL Int type, and that $hour is an Int. The comparison operators can't compare strings.
