How can I call a mySQL function from a form directly or via PHP functiuon

A bit off the side I guess but I need to execute a function something like this

select similarMembers ('nick', 'ogbourne', 'bwyatt@netspeed.com.au', '94 Owen St', null, '0409206971', '1947-11-18', 2) from dual;

and then pick up the data loaded by that function into the table u3a_00_temp;

select * from u3a_00_temp;

Can I do that??? and if so how?????
Regards
Nick
