help to build template!

netdur

ok, I failed to build my own template, I wanted it to be fast and easy-to-use... I am posting code here with hope someone can finish it!
well, it's simple class include four functions... file(), area(), loop() and show()... the only part I couldn't done is the loop function, I really got suck trying to programming it, I still did not grub logic (also my education can't leave me time to do that... sorry) but other functions is fine...
here the source code and example!

template.core.php

<?Php
class tmpl {
var $file;
function file($file, $path = '.')
{
	if (!is_dir($path. '/'))
	{
		die('Template: Cannot access directory "<i>./' .$path. '</i>"');
		return FALSE;
	}
	$stream = fopen($path. '/' .$file, "r");
	if (!$stream)
	{
		die('Template: Cannot access file "<i>' .$path. '/' .$file. '</i>"');
		return FALSE;
	}
	$content = fread($stream, filesize($path. '/' .$file));
	fclose($stream);
	$count = count(explode('<include="', $content)) - 1;
	if ($count != 0)
	{
		for ($i = 0; $i < $count; $i++)
		{
			$begin	= strstr($content, '<include="');
			$str_num	= strpos($begin, '" />') - 10;
			$name		= substr($begin, 10, $str_num);
			$include	= '<include="' .$name. '" />';
			$stream  = fopen($path. '/' .$name, "r");
			if (!$stream)
			{
				die('Template: Cannot access file "<i>' .$name. '</i>" to include');
				return FALSE;
			}
			$to_include = fread($stream, filesize($path. '/' .$name));
			fclose($stream);
			$file = str_replace($include, $to_include, $content);
		}
	}
	$this->file = $file;
}
function area($name, $state = 'hide')
{
	if ($state == 'hide')
	{
		$begin= strstr($this->file, '<area="' .$name. '">');
		$area	= explode('</area="' .$name. '">', $begin);
		$this->file = str_replace($area[0], '', $this->file);
		$this->file = str_replace('</area="' .$name. '">', '', $this->file);
	}
	if ($state == 'show')
	{
		$this->file = str_replace('<area="' .$name. '">', '', $this->file);
		$this->file = str_replace('</area="' .$name. '">', '', $this->file);
	}
}
function loop($loop, $variable, $value)
{
/* here where I failed */

}
function show($var)
{
	while (list($key, $val) = each($var))
	{
		$this->file = str_replace('$' .$key, $val, $this->file);
	}
	print($this->file);
}

/* end of class's code */ }

// example //

$tmpl = new tmpl;
$tmpl->file('index.htm');
$var['title']	= 'MyPRO';

$con = mysql_connect('localhost', 'root', '');
$query = mysql_query('SELECT * FROM phpbb2.phpbb_config');
while ($value = mysql_fetch_array($query))
{

$tmpl->loop('data', 'config_name', $value[0]);
$tmpl->loop('data', 'config_value', $value[1]);

}
mysql_free_result($query);
mysql_close($con);
$tmpl->area('first', 'show');
$tmpl->show($var);
?>

index.htm

<include="head.htm" />
  <body />
  <area="first"><center>header</center></area="first">
   <ul>
    <loop="data">
     <li>config name = $config_name, config value = $config_value
    </loop="data">
   </ul>
</html>

head.htm

<html>
  <head>
    <title>$title</title>
  </head>

Can you be more specific as to what doesn't work, and include any errors you got. That'll make it easier for us in trying to assist you.

it's all about loop function, I guess it must wrote from scratch, function I already wrote was look like this, but this is not usefull! if you want a loop inside loop

$names = array('Donald', 'April', 'Adel');
$age = array('56', '16', '23');
$city = array('New York', 'Erie', 'Rabat');
$records = array('name' => $names, 'age' => $age, 'city' => $city); 

$keys    = array_keys($records);
for ($i = 0; $i < 1; $i++){
    for ($x = 0; $x < count($records[$keys[$i]]); $x++){
        $to_loop = '<li>My name is <!--name-->, I am a <!--age--> years old, I live in <!--city--> city</li>';
                    for ($y = 0; $y < count($keys); $y++){
            $to_loop = str_replace('<!--' .$keys[$y]. '-->', $records[$keys[$y]][$x], $to_loop);
        }
                    $loops .= $to_loop;
    }
}

second was this

function loop($loop, $variable, $value)
{
	$begin= strstr($this->file, '<loop="' .$loop. '">');
	$area	= explode('</loop="' .$loop. '">', $begin);
	$area = str_replace('<loop="' .$loop. '">', '', $area[0]);
	$loop = str_replace('$' .$variable, $value, $area);
	$this->file = str_replace($area, $loop, $this->file);
}

this work but output only one result! the first row, I did not work much on it
