PLPGSQL - PHP data querying

Dear All:

Regarding PHP & PLPGSQL Programming. I am new to
PLPGSQL.

I wish someone suggest me the solution for the below
requirement even though it is very simple as I am new
to the subject and could not find an answer which I
can understand.

I have a table by name 'users' with several columns.

I want to query "select * from users' from PHP to
Postgresql through PLPGSQL.

Therefore I need

1. The practical syntax for the PLPGSQL function

2. The practical syntax for calling and displaying of
the returned recordset from PHP.

With the above I would be able to develop futher
programs.

I would be thankful for the same.

Thanks in advance

Regards

Ganesh
