my $search_for = join '|', map quotemeta, keys %replace;
...
s/\$($search_for)/$replace{$1}/g;
Additionally:
when doing things like this and you have two hash keys "foo" and "foobar", either use \b in the regex if possible, or sort the hash keys for length before joining. otherwise $foobar could be replaced with the value of $replace{foo}.
s/\$($search_for)\b/$replace{$1}/g;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
