Writing a function

[micmac]

Hi all,
Can anyone give me some pointers on writing the below script as a custom made function?

<TABLE cellSpacing=0 cellPadding=0 width=100% border=0>
                                      <TR> 
                                        <TD class=bgdrkgrey colSpan=6 height=1></TD>
                                        <hr width="100%" noshade>
                                      <TR> 
                                        <TD colSpan=6 height=5></TD>
                                      </TR>
                                      <TR> 
                                        <TD class=text2bold noWrap>Skip to Page&nbsp;&nbsp;

									                                          <?
if($page != 1)
$pageprev = $page - 1; 

$numofpages = $totalrows / $limit; 
for($i = 1; $i <= $numofpages; $i++){ 
if($i == $page) 
echo "<img src=\"images/page_number_". $i ."_active.gif\">";
else 
echo("<a href=\"genre.php?genre=$genre&sortby=$sortby&page=$i\"><img border=\"0\" src=\"images/page_number_". $i .".gif\"></a>"); 
} 
if(($totalrows % $limit) != 1){ 
if($i == $page) 
echo "<img src=\"images/page_number_". $i ."_active.gif\">"; 
}else if($totalpagerows != $limit){

if(($totalrows - ($limit * $page)) > 0){ 
$pagenext = $page + 1;
?>
&nbsp; </TD>
<TD align=right>
<?
if($page != 1){
$pageprev = $page - 1;
echo("<a href=\"genre.php?genre=$genre&sortby=$sortby&page=$pageprev\"><img border=\"0\" src=\"images/prev_page_arrow.gif\"></a>&nbsp;"); 
}else

echo("&nbsp;"); 
?>
<? 
echo("<a href=\"genre.php?genre=$genre&sortby=$sortby&page=$pagenext\"><img border=\"0\" src=\"images/next_page_arrow.gif\"></a>"); 
}else if($totalpagerows != $limit){
echo("&nbsp; </TD><TD align=right><a href=\"genre.php?genre=$genre&sortby=$sortby&page=$pageprev\"><img border=\"0\" src=\"images/prev_page_arrow.gif\"></a>"); 
}
?>

                                      </TD>

                                  </TR>
                                  <TR>

                                  </TR>
                                  <TR> 
                                    <TD class=text2bold width=200>Items <? echo ($page * $limit) - ($limit - 1) ?>-<? echo ($page * $limit) + ($totalpagerows - $limit) ?> 
                                      of <? echo $totalrows ?> Results</TD>

                                  <tr> 
                                    <td colspan="2"></td>

                                  </TR>
                                  <TR></TR>
                                </TABLE>

find the varuables that are assumed to exist before this function runns

at first glance one would be $page

the simply wrap up what you have in

function TheFunction ( $page, $other_var, $other_var )
{
    .... your code line for line ....

}

or if you don't want to pass in the variables explicityly

function TheFunction ()
{
    global $page;
    global $var_that_exists_before_function_call;
    global $var_that_exists_before_function_call;

.... your code line for line ....
}
