Question

hi cnt seem to understand clearly about the relationship of two tables being merged pls help im new to coding and I want to learn more coz I can't understand how the relationship works

Answer 1

I think you misunderstand the php function array_merge() with SQL related tables.
- Php array_merge() functionmerges two php arrays and has nothing common with relationship.
- Sql is relative database which have a tables connected with relations
