I want to do something like:
class Name{
function assign($name,$value){
}
}
Which is pretty much the same as assign in smarty
$smarty->assign('name',$value);
$smarty->display("index.html");
How to implement this?

A:
I would say
class Name{
private $_values = array(); // or protected if you prefer
function assign($name,$value){
$this->_values[$name] = $value;
}
}

This way only one variable can be assgigned.

A:
The question's a little vague. If you want to keep the $value of $name around for future use you could do something like:
class Name {
protected $_data= array();
function assign($name,$value) {
$this->_data[$name]= $value;
}
}
Then to make the variables available in an included template file:
class Templater {
protected $_data= array();
function assign($name,$value) {
$this->_data[$name]= $value;
}
function render($template_file) {
extract($this->_data);
include($template_file);
}
}
$template= new Templater();
$template->assign('myvariable', 'My Value');
$template->render('path/to/file.tpl');
And if path/to/file.tpl contains:
<html>
<body>
This is my variable: <b><?php echo $myvariable; ?></b>
</body>
</html>
You would get output like this
This is my variable: My Value

A:
class Name{
private $_vars;
function __construct() {
$this->_vars = array();
}
function assign($name,$value) {
$this->_vars[$name] = $value;
}
function display($templatefile) {
extract($this->_vars);
include($templatefile);
}
}
The extract() call temporarily pulls key-value pairs from an array into existence as variables named for each key with values corresponding to the array values.

Do you think this is MVC?I can see it separates View and Logic,but I don't know Modal and Control.Do you?

Usually where you'd *get* the data to pass to `assign()` would be from a model. Since there's no actual data being used here, you're only going to see elements of the view and the controller.

A:
you should create global registry class to make your variables available to your html file.
class registry { private $data = array();
static function set($name, $value)
{
$this->data[$name] = $value;
}
static function get($value)
{
return isset($this->data[$name]) ? $this->data[$name] : false;
}
}
and access like this from your files:
registry::get('my already set value');
