Stored Procedure didn't execute all the data - php

Question

I got a problem while executing my stored procedure in web service that I create in PHP language. If I execute the SP below directly in SQL Server Management Studio, it works perfectly. But when I execute the SP from my web service with PHP, it only executes some of the data in the looping I made in SP.
I got a service table as a master room data. In that SP below, I would like to check is the room available in a date range that I input to stored procedure one by one.
For example, I got 6 rooms in service table, and I want to check it one by one in looping with cursor. When I execute the SP in web service, it only execute 4 rooms in looping, but if I execute the SP in management studio directly, it works perfectly.
Can somebody help me to solve this problem?
Thank you.
Create Procedure GetAvailableRoom
#Date1 Datetime,
#Date2 Datetime,
#UserID Varchar(15)
AS
Begin
Delete From Room_Availability Where UserID = #UserID
Declare #KL Varchar(50)
Declare Cursor_RA Cursor For SELECT Service_Code FROM Services Where Status = 'ROOM' Order By Service_Code
Open Cursor_RA
Fetch Next From Cursor_RA Into #KL
While ##FETCH_STATUS = 0
Begin
print #KL
Declare #MyDate DateTime
Set #MyDate = #Date1
Declare #Diff Int
Set #Diff = DateDiff(Day, #Date1, #Date2)
Declare #Counter Int
Set #Counter = 0
print #MyDate
print #Diff
print #Counter
While (#Counter <= #Diff)
Begin
Print 'My Date is ' + Convert(Varchar, format(#MyDate,'yyyy-MM-dd'))
if exists(SELECT #KL, format(#MyDate,'yyyy-MM-dd 00:0:00'), Customers.Name + ' | ' + Customers.HP, #UserID
FROM Reservation INNER JOIN Reservation_Details ON Reservation.Reservation_Code = Reservation_Details.Reservation_Code
INNER JOIN Customers ON Reservation.Customer_ID = Customers.Customer_ID
WHERE Reservation_Details.Kode_Service = #KL AND
Reservation_Details.Checkin <= format(#MyDate,'yyyy-MM-dd 23:59:59') AND
Reservation_Details.Checkout >= format(#MyDate,'yyyy-MM-dd 00:0:00'))
Begin
print 'exists'
Insert Into Room_Availability (Service_Code,Service_Date,Customer,UserID)
SELECT #KL, format(#MyDate,'yyyy-MM-dd 00:0:00'), Customers.Name + ' | ' + Customers.HP, #UserID
FROM Reservation INNER JOIN Reservation_Details ON Reservation.Reservation_Code = Reservation_Details.Reservation_Code
INNER JOIN Customers ON Reservation.Customer_ID = Customers.Customer_ID
WHERE Reservation_Details.Service_Code = #KL AND
Reservation_Details.Checkin <= format(#MyDate,'yyyy-MM-dd 23:59:59') AND
Reservation_Details.Checkout >= format(#MyDate,'yyyy-MM-dd 00:0:00')
End
Else
Begin
print 'not exists'
Insert Into Room_Availability (Service_Code,Service_Date,Customer,UserID)
Values(#KL, format(#MyDate,'yyyy-MM-dd 00:0:00'), 'EMPTY', #UserID)
End
Set #MyDate = dateadd(dd,1,#MyDate)
Set #Counter = #Counter + 1
End
Fetch Next From Cursor_RA Into #KL
End
Close Cursor_RA
Deallocate Cursor_RA
End
This is the web service code.
