<?php
function Object($object)
{
static $result = array();
if (class_exists($object, false) === true)
{
if (array_key_exists($object, $result) === false)
{
$result[$object] = new $object();
}
return $result[$object];
}
else if (is_file('./' . $object . '.php') === true)
{
$class = basename($object);
if (array_key_exists($class, $result) === false)
{
if (class_exists($class, false) === false)
{
require('./' . $object . '.php');
}
$result[$class] = new $class();
}
return $result[$class];
}
return false;
}
