Is current date within specified date/time range in PHP - php

Question

I am creating a website that allow deliveries only within certain delivery time frames.
Here is an example of exactly what I'm looking for:
FakeCompany delivers on Wednesday and allows customers to place orders between Friday and Tuesday with a cutoff time of 11 PM on Tuesday night.
I need to figure out when the customer logs in if ordering is allowed (between Friday - Tuesday 11 PM). I also need to know how much longer they have to order.
I know the PHP date('N') function that Friday is 5:
date('N', strtotime('Friday'));
and Tuesday is 1:
date('N', strtotime('Tuesday'));
These time ranges may change, so I need a simple solution.
Here is what I started with, and now I'm lost on how to do this.
//Set today and get from database start / end days and end time
$today = (int)date('N');
$startDay = (int)date('N', strtotime('Friday'));
$endDay = (int)date('N', strtotime('Tuesday'));
$endDayTime = '11:00:00';
//If today is before start date
if($today >= $startDay && $today <= $endDay){
//This works only if the end date is not the following week
//It also needs to be before end day time!
}
I think I need to get the date of the week based on the DAY (Friday) and convert that to this weeks Friday if Friday has not passed or next weeks Friday and do the same with end date.
Then I need to know if today is between those dates / times.

Answer 1

$now = new DateTime();
$tuesday = new DateTime('last Tuesday');
$friday = new DateTime('Friday 11pm');
if ($tuesday < $now && $now < $friday) {
$interval = $friday->diff($now);
echo $interval->format('%d day %h hours %i minutes left to order');
}
else {
echo "you can't order now";
}

Here is a function to check that today is an approved day then if its tuesday also make sure it is before 11pm:
/*
Acceptable days:
5 - friday
6 - saturday
7 - sunday
1 - monday
2 - tuesday
*/
//Can they order today?
if(in_array(date('N'),array(1,2,5,6,7))){
//if today is tuesday is it before 11pm?
if(date('N') == 2){
if(date('H')<23){
//23 = 11pm in 24 hour time
//Then can order
}
else{
//Then CANT order
}
}
//Its not tuesday so we dont care what time it is they can order
}

Answer 3

for the end day I think you could do it like this:
$endDay = (int)date('N', strtotime('Friday') + 3 * 24 * 3600 + 23 * 3600);
strtotime('Friday') to get friday and add 3 days of 24 hours to it, and it'll be Tuesday 0 am. Then you add 23 hours time to it as it finish at 11pm.
$today = (int)date('N');
$startDay = (int)date('N', strtotime('Friday'));
$endDay = (int)date('N', strtotime('Friday') + 3 * 24 * 3600 + 23 * 3600);
//If today is before start date
if($today >= $startDay && $today <= $endDay){
//now it works
}

Answer 4

Here is exactly what I am looking for.
The dates provided may not be this week or even this month, so we need to figure out based on the date what the day of the week was and set the date on this week or next week to same day depending on today (kinda confusing).
