how to run code after a specific time - php

Question

I'm trying to display some content based on a hour.
This hour is coming from DB as string field.
If the current time match or passed the time from DB, a certain content should be displayed else it's the default content
What i've tried so far :
$time = strtotime($p_objetct->getHour());
//we check if this has already passed to
//retrieve corresponding content else we display default content
if ($time >= date("h:i:sa")) {
echo 'time to display new content !';
}else{
echo 'display content default';
}
This code is not working well as you can guess 'cause if I want to display new content at 20:00:00, the 1st condition is true when the current time is 08:00:00..
I've also tried that
$time = strtotime(p_objetct->getHour());
$selection = floor((date('G',$time) / 2));
switch ($selection) {
case 0:
echo 'time between 0-2!';
break;
case 1:
echo 'time between 2-4!';
break;
case 2:
echo 'time between 4-6!';
break;
case 3:
echo 'time between 6-8!';
break;
case 4:
echo 'time between 8-10!';
break;
case 5:
echo 'time between 10-12!';
break;
case 6:
echo 'time between 12-14!';
break;
case 7:
echo 'time between 14-16!';
break;
case 8:
echo 'time between 16-18!';
break;
case 9:
echo 'time between 18-20!';
break;
case 10:
echo 'time between 20-22!';
break;
case 11:
echo 'time between 22-24!';
break;
}
But this wasnt the good approach because i cant guess in which case the time from DB will be..
Any ideas are welcomed !
Edit :
I have 2 contents (new and default).
The new content should be display from time from DB until 00:00:00 then it should be the default one

If you get only the hour in 24h format from your $p_objetct->getHour() method you can simply compare it to date('H');.
If you wat exact matches you can use:
<?php
$hourToCheck = $p_objetct->getHour();
$currentHour = date('H'); // As of PHP manual "H" returns the hour in 24h format
$contentToDisplay = "What ever you wanna display as default.";
if ($hourToCheck === $currentHour) {
$contentToDisplay = "Your matching content.";
}
If you need it as a lower bound time feel free to use and change this snippet:
<?php
$hourToCheck = $p_objetct->getHour();
$currentHour = date('H'); // As of PHP manual "H" returns the hour in 24h format
$contentToDisplay = "What ever you wanna display as default.";
if ($hourToCheck <= $currentHour) {
$contentToDisplay = "Your matching content 1.";
}

You could try to set a variable with a name based on time, matching an existing file with that name and require it with php. Like this:
<?php
$time = date('H',time());
$name_of_content_to_require = false;
switch ($time) {
case 0:
$name_of_content_to_require = '0-2';
break;
case 1:
$name_of_content_to_require = '2-4';
break;
case 2:
$name_of_content_to_require = '4-6';
break;
case 3:
$name_of_content_to_require = '6-8';
break;
case 4:
$name_of_content_to_require = '8-10';
break;
case 5:
$name_of_content_to_require = '10-12';
break;
case 6:
$name_of_content_to_require = '12-14';
break;
case 7:
$name_of_content_to_require = '14-16';
break;
case 8:
$name_of_content_to_require = '16-18';
break;
case 9:
$name_of_content_to_require = '18-20';
break;
case 10:
$name_of_content_to_require = '20-22';
break;
case 11:
$name_of_content_to_require = '22-24';
break;
}
if( $name_of_content_to_require ) {
require_once __DIR__ . $name_of_content_to_require . '.php';
} else {
die('with some error, or throw an exception');
}
