Cannot loop mysql data into template

HPH

Hello, I got a problem, namely I'm trying to do a webpage by using templates, I was doing really well until it reached to point where I had to take some data form mysql database and loop it to template, I checked some tutorials and tried to work it out bu myself but it didn't happen and I'm still struggling with that issue.

Namely, my code (functions works fine when I am printing a template without mysql data):

<?php
$hostname="xxx";
$username="xxx";
$password="xxx";
$database="xxx";

function read_template($filename) 
{ 
    $source = join("",file($filename)); 


if (strlen($source) == 0) 
{ 
    die("Templatefaili ei õnnestud avada!"); 
}; 

return $source; 
}; 


function parse_template($source,$vars) 
{ 
    if (is_array($vars)) 
    { 
        foreach($vars as $key => $value) 
        { 
            $tag = "{VAR:" . $key . "}";  

        $source = str_replace($tag,$value,$source); 
    }; 
}; 

return $source; 
} 

	$db = mysql_connect($hostname,$username,$password);
	mysql_select_db($database,$db);

	$sqlmd = "SELECT * FROM uudised ORDER BY id DESC";
	$result = mysql_query($sqlmd) or die ("Uudiste kuvamine ebaõnnestus ".mysql_error());

	$results = array();
	$i = "1";
	while($row = mysql_fetch_array($result))
	{
		$tmp = array( 
            'lisaja' => $row['lisaja'], 
            'aeg'=> $row['aeg'] 
        ); 
        $results[$i++] = $tmp;
	}

$main_template = "esileht.tpl";
$frame_tpl = read_template($main_template);
$vars = array("results" => $results);
$site_html = parse_template($frame_tpl, $vars);
print $site_html;
?>

And that is my template "esileht.tpl" where I try to loop mysql data:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE>Katsetused :D</TITLE>
</HEAD>

<BODY>
{section name=news loop=$results} 
{VAR:results[news].lisaja}<BR>
{VAR:results[news].aeg}<BR>
{/section} 

</BODY>
</HTML>

When I try to print my mysql data, the browser prints only empty tags, no data, this is that browser prints...

{section name=news loop=$results} {VAR:results[news].lisaja}
{VAR:results[news].aeg}
{/section}

...and nothing else. I have no idea what to do, I have tried many different options but nothing seems to work. I hope you can help me to seolve my problem.

Good luck,
HPH
