Iterating through numbers

A while back I asked about how to display the numbers in a format so that you don't see all of the Page Numbers but only a 3 before and 3 after the current number Example:
First | Previous | 1 | 2 | 3 | Current | 4 | 5 | 6 | Next | Last

It might not be the most efficient code in the world but it works pretty good.

function show_navigation($displayname = "Page"){

echo "<div class='HFPagination'>";

$var = $this->get_var;
$total_row = $this->get_total_rows();
$total_page = $this->get_num_pages() * $this->num_per_page;
$total_max = ($total_page - $total_row);
$current_page = $this->set_page() +1;
$previous_page = $current_page - 2;
$last_page = $this->num_of_pages - 1;

//For the first page
if($current_page == 1){
for($PageCount = 0; $PageCount <= 4; $PageCount++){
if($PageCount == $current_page - 1){
echo "<b>".($PageCount+1)."</b>";
}else{
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=".$PageCount.$this->rebuild_qs($var)."\">".($PageCount+1)."</a>";
}
}
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=".$current_page.$this->rebuild_qs($var)."\"> Next ></a>";
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=".$last_page.$this->rebuild_qs($var)."\">Last Page >></a>";
}

//For the current Page
if($current_page > 1 && $current_page < $this->num_of_pages){
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=0".$this->rebuild_qs($var)."\"><< First Page</a>";
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=".$previous_page.$this->rebuild_qs($var)."\">< Previous</a>";
for($PageCount = $current_page - 2; $PageCount <= $current_page; $PageCount++){
if($PageCount > 1){
$previous_page = $PageCount - 2;
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=".$previous_page.$this->rebuild_qs($var)."\">".($PageCount - 1)."</a>";
}
}
echo "<b>".($current_page)."</b>";
for($PageCount = $current_page; $PageCount <= $current_page + 2; $PageCount++){
if($PageCount <= $last_page){
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=".$PageCount.$this->rebuild_qs($var)."\">".($PageCount+1)."</a>";
}
}
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=".$current_page.$this->rebuild_qs($var)."\">Next ></a>";
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=".$last_page.$this->rebuild_qs($var)."\"> Last Page >></a>";
}

//For the last page
if($current_page == $this->num_of_pages){
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=0".$this->rebuild_qs($var)."\">First Page</a>";
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=".$previous_page.$this->rebuild_qs($var)."\">< Previous</a>";
for($PageCount = $this->num_of_pages - 4; $PageCount <= $this->num_of_pages; $PageCount++){
$previous_page = $PageCount - 2;
echo "<a href=\"".$_SERVER['PHP_SELF']."?".$this->get_var."=".$previous_page.$this->rebuild_qs($var)."\">".($PageCount - 1)."</a>";
}
echo "<b>".$this->num_of_pages."</b>";
}
echo "</div>";
}
