Customize PHP Scripts

I'll provide you 3 scripts: 1. iBiiling CRM: [login to view URL] 2. osTicket: [login to view URL] 3. Orangescrum: [login to view URL] All you need to make common login session of all the above scripts. Explanation: I want to link the osTicket and Orangescrum with iBilling CRM. If any customer or staff registers on the iBilling CRM, the registration info (including login email and password) will be stored to some tables in MySQL database. I want the osTicket and Orangescrum to use the same database tables. All the scripts should use the same login session. So that If anyone logins to the iBilling CRM, he also automatically gets login to the osTicket and Orangescrum. There will be no any separate login or registration page for osTicket and Orangescrum. Whenever a user logs out, he will automatically gets logged out from all the scripts. Please remember, the common login session should work for both client tables and admin/staff tables. I'll provide you all the above scripts. Please see the Live Previews of the above scripts. You need to understand all the above scripts as per my requirements. You also need to provide me the modified and newly added files of the scripts separately. Also you need to send me the backup files of the modified database table structures. Thank you!
