replace??

hello,

i have the following problem:
i have in php an array structure with user-prefs that have to be stored
onto DB....

actually i look up if the corresponding entry exists (comparing
user-name and field-name) if yes i update, if no i insert....

this isn't very appealing, but i couldn't find another way yet to make
this shorter...

would be nice if something like the following existed:

replace settings set auser='toto',field='lang',data='fr' where
auser='toto' and field='lang';

update settings set auser='toto',field='lang',data='fr' where
auser='toto' and field='lang' REPLACE;

or even better:

replace settings keys(auser,field) set auser='toto',field='lang',data='fr';
