PHP function in a template

[T_Richardson]

I have this users.php function code to list online users. I would like to include this on a non-vb page that uses templates.

<?
chdir('./');
require_once('./global.php');

// ---------------------------------------------------
// Start Globalized Function - LoadTemplate
// ---------------------------------------------------

function LoadTemplate($template = ""){

$template = "vBExternal/{$template}";

if(!file_exists($template)){
RunError("System was unable to find the template '{$template}'");
}

if(!$Handler = fopen($template,'r')){
RunError("System was unable to open the template '{$template}'");
}

$template = fread($Handler,filesize($template));
fclose($Handler);

return $template;
}

// ---------------------------------------------------
// Start Globalized Function - RunError
// ---------------------------------------------------

function RunError($message = ""){
echo "<font size='1' face='verdana'>There was an error while processing vBExternal:<br />{$message}</font>";
exit;
}

// ---------------------------------------------------
// End Globalized Function - RunError
// ---------------------------------------------------

// ---------------------------------------------------
// Start Globalized Function - ParseTemplate
// ---------------------------------------------------

function ParseTemplate($template, $parser = array(), $doGlobals = 0){
global $vbulletin;

if(is_array($parser)){
foreach($parser as $find => $replace){
$template = str_replace("{".$find."}", $replace, $template);
}
} else if($doGlobals){
$RepGlobals = array(
'url' => $vbulletin->options['bburl'],
);

foreach($RepGlobals as $find => $replace){
$template = str_replace("{".$find."}", $replace, $template);
}

}

return $template;
}

// ---------------------------------------------------
// End Globalized Function - ParseTemplate
// ---------------------------------------------------

function output_UsersOnline(){
global $db, $Data, $vbulletin;

// Load Template
$Template = LoadTemplate("users_online.html");

$cache = array();

// Collect Data
$datecut = TIMENOW - $vbulletin->options['cookietimeout'];
$UsersOnline = $db->query("
SELECT
user.username, (user.options) AS invisible, user.usergroupid,
session.userid,
IF(displaygroupid=0, user.usergroupid, displaygroupid) AS displaygroupid
FROM " . TABLE_PREFIX . "session AS session
LEFT JOIN " . TABLE_PREFIX . "user AS user ON(user.userid = session.userid)
WHERE session.lastactivity > $datecut and user.userid > 0
" . iif($vbulletin->options['displayloggedin'] == 1, "ORDER BY username ASC") . "
");

while($User = $db->fetch_array($UsersOnline)){
if(!$cache[$User['userid']]){
$cache[$User['userid']] = $User['userid'];

$Data .= ParseTemplate($Template,
array(
'userid' => $User['userid'],
'username' => $User['username'],
)
);
}
}

unset($cache);
doOutput();
}

function doOutput(){
global $Data, $vbulletin;

$Data = str_replace('images/',"{$vbulletin->options[bburl]}/images/",$Data);

echo ParseTemplate($Data,"",1);
$Data = "";
}

?>




That php file works if you include output_UsersOnline() in the file itself.

What would be the proper way construct this code in a plugin so I can call it in a template with a variable ie; $onlineusers

If you are including global.php already, why making custom functions for already built in functionality? (Fetching templates and parsing them.)

Have you looked at this tutorial? :

It should point you in the right direction.

The template that it's parsing is an html page that puts the users online in clickable link to they're profile.

Anyone have any idea. Surely there's some guru out there that can point me in the right direction :)
