ereg_replace multiple instances

[Anon]

How could I consolidate the folowing to a single statement?

ereg_replace (" ", "", $myString);
ereg_replace ("-", "", $myString);

Thanks, Corey

$s = array('_', ' ');
$r = array('', '');

preg_replace($s, $r, $myString);

$myString = preg_replace('/[\s_]*/','',$myString);

If it's just simple like that, using str_replace would be much more efficient (faster)
