[PHP] php/mysql search. need help

[lizlynch]

i have a form where a user inputs a home service type and this results in a list of 
that value, eg a user inputs 'plumber' and a list of plumbers is displayed. 
if a user accidentally types plumbar no results are displayed.
 is there anyway of making php/mysql recognise the first three letters or give a 
closest match to the query.

yours liz lynch
