应用程序中的数据库连接管理

Question

I am developing a application that is in php and PostgreSQL .

What I want to know is which of these is best?

1. I should create connection every time i have to make a query like using pg_connect and close it after the query operations
2. Or should i start the connection first time at the initial launch

Please guide me the correct way to achieve my objective.

Answer 1

Connect at the start of your script, close it at ending. No need to re-connect on each query.
