php show event if server date/time is between two time values - php

Question

I'm not trying to do this with MySQL as I see is common. I am merely trying to create a PHP Script that will display information like this using the servers time and date as a reference:
Monday 2:30am to Tuesday 2:29am - Content A
Tuesday 2:30am to Wednesday 2:29am - Content B
Wednesday 2:30am to Thursday 2:29am - Content C
and so on....
Until every day of the week in covered, for some reason I can't seem to nail this and there doesn't seem to be and examples to build from. Is this for some reason not possible?
Edit
I've used the following code and it's proving to not be as reliable as it should be.
function isInTimeWindow($dayName, $startHour, $startMinute, $endHour, $endMinute)
{
$dayName = ucfirst($dayName);
list($dayNow, $timeNow) = explode('|', date('l|Hi'));
return (
ucfirst($dayName) == $dayNow and
$timeNow >= sprintf('%02d%02d', $startHour, $startMinute) and
$timeNow <= sprintf('%02d%02d', $endHour, $endMinute)
);
}
// tuesdays during day
if(isInTimeWindow('tuesday', 02, 30, 23, 00)) {
?>
CONTENT
<?php } ?>

Answer 1

you could use date(l) php manual date() function function to get the actual weekday in words (Monday, Tuesday, ... ) so you can check the weekday.
Use mktime function php manual mktime() function to convert your times ( Monday, 2:30am for example ) into timestamps and check if it is between current time by using time function php manual time() function
EDIT: Here's an example:
$today_start = mktime(2, 30, 0, date('m'), date('d'), date('Y'));
$today_end = mktime(2, 29, 0, date('m'), (date('d') + 1), date('Y'));
if ( $today_start < time() && $today_end > time() )
// code
mktime works like this: mktime( hour, minutes, seconds, month, day, year )

Answer 2

So long as you're happy using the server's time rather than the client's time this can be done using the getdate() function.
For example, if you just wanted to do it based on day of the week:
<?php
$now = getdate();
switch($now['wday']) {
case 0:
?>
Content A
<?
break;
etc.
Edit: here is how to do it in more detail:
getdate() provides you with information about the hour and minute parts too.
You could have a function like :
// Get's the 0-indexed day of the week offset so each "day" starts and 2:30am
function get_offset_day() {
$now = getdate();
if ($now['hours']*60 + $now['minutes'] < 150) { // less 2h 30m after midnight => still "yesterday"
$answer = $now['wday']-1;
}
else {
$answer = $now['wday'];
}
if ($answer < 0) return 6;
return $answer;
}
