Need help with php and preg

Here's a test of what I'm working on:
http://www.bikerleatherbarn.com/tag.php

What I'm looking to do is have the tags display like "blue widget", but the url will be http://www.domain.com/search-blue+widget-blended,(notice the + between blue and widget). I somehow need to replace a space ( ) with +. Below is the code for that page:

<?php
$CFG['db_host'] = 'localhost';
$CFG['db_user'] = 'user_name';
$CFG['db_pass'] = 'password';
$CFG['db_name'] = 'database_name';

mysql_connect($CFG['db_host'], $CFG['db_user'], $CFG['db_pass']) or die(mysql_error());
mysql_select_db($CFG['db_name']);

function tag_info() {
$result = mysql_query("SELECT * FROM tags GROUP BY tag_name ORDER BY RAND() DESC LIMIT 40");
while($row = mysql_fetch_array($result)) {
$arr[$row['tag_name']] = $row['count'];
}
//ksort($arr);
return $arr;
}

function tag_cloud() {
$min_size = 14;
$max_size = 22;

$tags = tag_info();

$minimum_count = min(array_values($tags));
$maximum_count = max(array_values($tags));
$spread = $maximum_count - $minimum_count;

if($spread == 0) {
$spread = 1;
}

$cloud_html = '';
$cloud_tags = array();
$tags = str_replace("","+",$tags);
$step = ($max_size - $min_size)/($spread);

foreach ($tags as $tag => $count) {
$size = $min_size + ($count - $minimum_count)
* $step;

// $size = ($max_size + $min_size)/$spread;

$cloud_tags[] = '<a style="font-size: '. floor($size) . 'px'
. '" class="tag_cloud" href="/search-' . $tag .'-blended'
. '" title="' . $count . ' searches for \'' . $tag . '\'">'
. htmlspecialchars(stripslashes($tag)) . '</a>';

}

$cloud_html = join("\n", $cloud_tags) . "\n";
return preg_replace('/\s\s+/', '+', $cloud_html);

return $cloud_html;
}
?>

<?php

if (!eregi('[.@\"\'!/:%]', $_GET['k']))
if (mysql_affected_rows()){
mysql_query("UPDATE tags SET count=count+1 WHERE tag_name=\"".$_GET["k"]."\"");
}
if (!mysql_affected_rows()){
mysql_query("INSERT INTO tags SET tag_name=\"".$_GET["k"]."\", count=1, search_date=NOW()");
}

?>

<form id="aom_search" name="search" method="GET" action="/tag.php" style="margin-bottom:0;"><table cellspacing=0 cellpadding=4 border=0 width="100%"><tr valign="middle"><td class="aom_sb"><span class="aom_sbt">Search</span></td><td class="aom_sb"><input id="aom_sbox" type="text" name="k" size="22" value=""></td><td class="aom_sb"><select name="c" id="aom_smenu"><option value="blended">All Products</option><option value="parts">Parts & Accessories</option></select></td><td class="aom_sb"><input type="submit" value="Search"></td></td></tr></table></form>

<?php print tag_cloud(); ?>

I know it has something to do with the line "return preg_replace('/\s\s+/', '+', $cloud_html);", but I'm not savvy enough with PHP to figure it out. As it is now, it's replacing two spaces ( ) rather than one space ( ) with the +. How do I replace just one space instead of 2 with a +? I'd also like the + not to show in the tag itself, but just in the url. I've tried for hours with no luck, can someone help me with this? I hope I've made myself clear...
