Upgrade PHP to 7.3

Hey Folks,

Just finished my blog to upgrade PHP to 7.3 version without hassles, I spent many hours to get this done.

Hope it helps for someone who needs.



Note: SuiteCRM isn’t ready for 7.3 yet… I tried it on 7.3 and got all sorts of warning messages. Went back to php 7.2 and all is fine.
