Persistance objects + importing

[<daniel@xxxxxxxxxxxxxxxx>]

Hi list, I am needing some advise on the best way of importing classes and
persistance, I am goingto supply some code, and would like to know if sessions or share memory is
the best way for it.It currently serializes and unserializes the class from a session , i
parse the directory and classusing pear naming standards, i can also send args to it. Let me know if
there is a better way ofdoing this, as from the talk serializing is also slow. I wonder if this
bit of code could ever becomea php extension ?? That would rock.

import 'PACKAGE_Classname'; or even import PACKAGE_Classname heh :)

becomes require_once('PACKAGE/Classname.php');

new PACKAGE_Classname(); //persist here dont reinclude per page.



function import($class_name,$serialize = null,$parse_dir = true,$args = null)
	{
			$parse_dir ? $filename = preg_replace("/_/","/",$class_name) : $filename =
$class_name;
			if ($serialize) {
				require_once($filename.".php");
			    if (!isset($_SESSION[''.$class_name.''])) {
					if (!$args) {
						$class = new $class_name;
					} else {
						$num_args = func_num_args();
						$params = func_get_args();
						$class= $this->_format_args($class_name,$num_args,$params);
					}
			        $_SESSION[''.$class_name.''] = serialize($class);
			    }
				return unserialize($_SESSION[''.$class_name.'']);
			} else {
				require_once($filename.".php");
				if (!$args) {
					return new $class_name;
				} else {
					$num_args = func_num_args();
					$params = func_get_args();
					return $this->_format_args($class_name,$num_args,$params);
 				}
			}

	}


function _format_args($class_name,$num_args,$params)
	{
		$code = "return new {$class_name}(";
		if ($num_args >= 4) {
			$args = array();
			for($i=3;$i<$num_args;$i++) {
				$args[] = '$params[' . $i . ']';
			}

			$code .= implode(',',$args);
		}
		$code .= ');';
 		return eval($code);
	}
