preg_match works, preg_replace does not - why?

Using PHP 5.1.4 (cli) (built: May 8 2006 08:41:41)

The following script seems to show a problem with preg_replace - trying
to replace zero or more ending / characters, with a single A character.

preg_match shows that it matched the two // characters, but
preg_replace, with same pattern, seems to match no characters. Any
help?

<?php
$s = "aa//";

preg_match('/\/*$/', $s, $a);

echo "matches :" . $a[0] . ":\n"; // output: matches ://:

preg_replace('/\/*$/', 'A', $s);

echo "after replace :$s:\n"; // output: after replace :aa//:
// should be aaA and not above
?>
