Here's what I got till but I have a problem...

<?php
  /*

Template Function Library

  */

  class class_template {
    var $root_folder;    //Stores root folder of template files
    var $file_content;   //Stores the content of tempalte files
    var $filenames;      //Stores the names of template files
    var $variables;      //File Handle for the template file
    var $key;            //Stores the variable for tempalte
    var $num;

function define($folder,$template_variables) {
  if(is_dir($folder)) {
    $this->root_folder = $folder;
  } else {
    $this->error_report("The root directory specified is not a directory!");
    exit();
  }
  $this->num = 0;
  while(list($key,$value) = each($template_variables)) {
    if(!file_exists($this->root_folder."/".$value)) {
      $this->error_report("$value does not exists!");
      exit();
    }
    $this->filenames[$i] = $value;
    $this->variables[$i] = fopen($this->root_folder."/".$value,"r");
    $this->key[$i] = $key;
    $this->num++;
  }
}

function assign($template_vairable,$value) {
  for($i = 0; $i != $this->num; $i++) {echo $this->filenames[$i];;
    $this->file_content[$i] = fread($this->vairables[$i],filesize($this->filenames[$i]));
    $this->file_content[$i] = str_replace("{$template_vairable}",$value,$this->file_content);
  }
  unset($i);
}

function print_print($order) {
  $order = explode(",",$order);
  $order_num = count($order);
  $i = 0; $n = 0;
  while($i != $this->num) {
    while($n != $this->num) {
      if($order[$i] == $file_content[$n]) {
        echo $file_content[$n];
        $n = 0;
        return false;
      }
    }
  }
}

function error_report($error_msg) {
  echo "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">
<html>
<head>
<title>Unexpected error has occured</title>
<meta http-equiv=\"Content-Type\" content=\"text/html; charset=iso-8859-1\">

</div>
</body>
</html>";
    }
  }
?>

in the function "assign" it tries to access $this->filename and $this->variable but it seems that it's empty. I tried accessing it on function "define" and it holds a value. This is causing the following error when I execute with the following code. The code above is called template.php and under a folder called "library"

<?php
  include("library/template.php");

  $tpl = new class_template();

  $tpl->define("library",array("basic" => "tpl.tpl"));

  $tpl->assign("CONTENT","hey");
?>

When I execute this I get this error:-

Warning: stat failed for (errno=2 - No such file or directory) in /usr/home/ticktaku/public_html/library/template.php on line 43

Warning: fread(): supplied argument is not a valid File-Handle resource in /usr/home/ticktaku/public_html/library/template.php on line 43

Now I have not got any idea why $this->filenames and $this->variables becomes empty... Please help :!:

I don't see you using fopen() anywhere - fread() wants a filepointer returned by fopen(), not a filename.

After thinking for a while I've come up with this code (hot_goblin thanks alot 8) )

<?php
  /*

Template Function Library

  */

  class class_template {
    var $root_folder;    //Stores root folder of template files
    var $file_content;   //Stores the content of tempalte files
    var $filenames;      //Stores the names of template files
    var $variables;      //File Handle for the template file
    var $key;            //Stores the variable for tempalte
    var $num;

function define($folder,$template_variables) {
  if(is_dir($folder)) {
    $this->root_folder = $folder;
  } else {
    $this->error_report("The root directory specified is not a directory!");
    exit();
  }
  $this->num = 0;
  while(list($key,$value) = each($template_variables)) {
    if(!file_exists($this->root_folder."/".$value)) {
      $this->error_report("$value does not exists!");
      exit();
    }
    $this->filenames[$this->num] = $value;
    $this->variables[$this->num] = fopen($this->root_folder."/".$value,"r");
    $this->key[$this->num] = $key;
    $this->num++;
  }
}

function assign($template_vairable,$value) {
  for($i = 0; $i != $this->num; $i++) {
    $this->file_content[$i] = fread($this->variables[$i],filesize($this->root_folder."/".$this->filenames[$i]));
    $this->file_content[$i] = str_replace("{$template_vairable}",$value,$this->file_content);
  }
  unset($i);
}

function print_template($order) {
  $order = explode(",",$order);
  $order_num = count($order);
  $order_num = $order_num - 1;

  for($i = 0; $i <= $order_num; $i++) {
    for($n = 0; $n <= $i; $n++) {
      if($this->key[$n] == $order[$i]) {
        list($content) = $this->file_content[$i];
        echo $content;
      }
    }
  }
}

function error_report($error_msg) {
  echo "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">
<html>
<head>
<title>Unexpected error has occured</title>
<meta http-equiv=\"Content-Type\" content=\"text/html; charset=iso-8859-1\">

<body>
<div align=\"center\"> <span style=\"font-family: Verdana, Arial, Helvetica, sans-serif; color: #FF0000; font-size: 12px; font-weight: bold;\">".$error_msg."</span>
</div>
</body>
</html>";
    }
  }
?>

This does everything fine except that when replacing {$template_variable} to $value the { and } still remains, why is that?

By the way I have opened the files Weedpacket...

        $this->variables[$this->num] = fopen($this->root_folder."/".$value,"r");

Weedpacket

Dunno why, but they're not needed anyway:

        $this->file_content[$i] = str_replace($template_vairable,$value,$this->file_content);
