 Designing a 'Restaurant System' using Php

Hope that helps You could just buy a few clearance 42" tvs which all display a syndication feed of the orders. Have the checkout app provide the syndication feed (be online or local, whatever). Would be cheaper than dev costs of implementing a sync and print system and much cooler. ;-)
As for your question about using PHP, it's possible and seems reasonable. Symfony could be used for the checkout app, but for printing in the kitchen you'll probably want to use shell scripts (or php as a shell script).

Online Hotel Booking System, Simultaneous Booking?

may help you . Use a locking construct (probably on the database level in this case) to ensure that only one confirmation will go through at once. You should always do this if it's possible to have a race condition like this. That way you will always know who was first, and you can tell the other user that they were too slow to confirm.
Another thing you might want to add is a payment time limit. In many systems, when you confirm something, you will have a certain amount of time to make a payment to get the reservation. If you don't pay within that time, the confirmation will expire and the room will once again be available.

To fix this issue trying to implement asynchronous methods in my repository classes code :
public async Task<Booking> CreateBookingAsync(Booking inBooking) {
Booking booking = new Booking();
...
await AddAsync(booking);
return booking;
}
[Route("api/PostBooking")]
[HttpPost]
public async Task<IHttpActionResult> PostBooking(BookingSystemServiceBookingViewModel inBooking)
{
...
uw.Services.AddBooking(await uw.Bookings.CreateBookingAsync(booking), inBooking.service.ServiceId);
uw.Complete();
return Ok();
}
public Booking CreateBooking(Booking inBooking) {
Booking booking = new Booking();
...
Add(booking);
return booking;
}
[Route("api/PostBooking")]
[HttpPost]
public async Task<IHttpActionResult> PostBooking(BookingSystemServiceBookingViewModel inBooking)
{
...
uw.Services.AddBooking(uw.Bookings.CreateBooking(booking), inBooking.service.ServiceId);
await uw.CompleteAsync();
return Ok();
}

 ColdFusion - Booking System - Booking Disappears

around this issue Issue - Race Conditions The problem is your current code is subject to race conditions. When multiple threads try and read and write a shared resource at the same time, only one of them can win. This is what happens when "John" an "Bob" try and sign up at the exact same time: code :
SELECT COUNT(*) AS EnrollmentsFound
FROM Enrollment
WHERE courseId = @courseId
AND studentId = @studentId
if ((select count(*) from Enrollment where courseId = @courseId) < @maxCapacity)
begin
insert into Enrollment (courseId, studentId )
values (@courseId, @studentId)
end
<!--- Exclusive lock to prevent race conditions / Access ONLY --->
<cflock name="Student_Enrollment_Add" type="exclusive" timeout="5000">
<cfquery name="getEnrollments" ...>
SELECT COUNT(*) AS EnrollmentsFound
FROM Enrollment
WHERE courseId = <cfqueryparam value="#form.courseId#" cfsqltype="cf_sql_integer">
</cfquery>
<cfif getEnrollments.EnrollmentsFound lt maxCapacity>
<cfquery ...>
INSERT INTO Enrollment ( .... )
VALUES ( .... )
</cfquery>
</cfif>
</cflock>
