You can avoid the temp table and return `setof record'. Just `RETURN
NEXT temp_result' after each test, where temp_result is your declared
working variable. When you're done with all tests, do the final RETURN.
No need for temp tables anywhere - your PHP invokes the function as
`SELECT * FROM test_something(args)' and gets a normal resultset back,
just as if it'd performed a SELECT from a table.

Personally, though I'd:

CREATE TYPE test_result AS (  test_id INTEGER, test_outcome TEXT );

or whatever's appropriate for your use, then declare the function as
`RETURNS SETOF test_result'.
