Get notification on video chat invitation

Question

I have developed an application and i have APIs to create video calls. currently my problem is if some one invites other persons to chat, how can i generate a notification for invitees? I am using PHP and MySQL for developing the application. currently i am thinking i should work this way: While inviting, a DB insertion will happen, i should check for this insertion with small interval (may be of seconds). If the person is invited, then he will get notification. Is this the usual practice? Please advice

Answer 1

I finally did it. Do not know if this is the best practice. I created a function to check any database change. I used setinterval to repeat the function with an interval of 5 seconds. And it did work :)
