Not sure what you mean by generic, and never used the db_placeholders
function, but this should work;

$skillnames = array("PHP", "HTML","SQL");
$tblname = "resubmt_skills";
$query = sprintf("SELECT skillid FROM %s WHERE skillname in ('%s')",
$tblname, "'".implode("', '",$skillnames)."'");
//execute and fetch query results here

not real elegant, but nothing is as elegant as the solution that works
and maintainers can understand.
