Just in case you wanted the nearest day rather than the next one, here is a way to do that.

$target = "Sunday";
$date   = "07.05.2010";

// Old-school DateTime::createFromFormat
list($dom, $mon, $year) = sscanf($date, "%02d.%02d.%04d");
$date = new DateTime("$year/$mon/$dom -4 days");
// Skip ahead to $target day
$date->modify("next $target");

echo $date->format("d.m.Y");

And as of PHP 5.3, that middle portion can be simply

$date = DateTime::createFromFormat("!d.m.Y", $date)
        ->modify("-4 days")->modify("next $target");
