I have an application that has core PHP for the signin, registration, dashboard. It has a front end and backend (dashboard). Simple stuff.
I need to implement a Scheduling system and EasyAppointments (EA) has 90% of the stuff I need.
EA uses codeigniter and requires login. It has it own login as well. So now we have the front site and dashboard with 1 core php signin. The EA has it signin codeigniter. I need to combine both. The developer wants to use the EA signing for everything, but it is not as robust as my signin (IP, lock out, roles, etc. )
I would like to know if it is true you can't combine core php with codeigniter.
And what is your suggestion: is it better to choose a framework over using core php?
Thank you for your time!
