Magento - 在块模板中未定义变量

Question

I am making a simple magento block and a template for it.

In my custom module I have a config.xml

<?xml version="1.0"?>
<config>
  <modules>
    <AAA_Recentproducts>
      <version>1.0</version>
    </AAA_Recentproducts>
  </modules>
  <global>
    <blocks>
      <recentproducts>
        <class>AAA_Recentproducts_Block</class>
      </recentproducts>
    </blocks>
  </global>
</config>

And this is my Block

<?php
class AAA_Recentproducts_Block_Recentproducts extends Mage_Core_Block_Template {
  public function getRecentProducts() {
    $products = Mage::getModel("catalog/product")
                    ->getCollection()
                    ->addAttributeToSelect('*')
                    ->setOrder('entity_id', 'DESC')
                    ->setPageSize(5);
    return $products;
  }
}

And finally my template file:

<?php
$products = $this­->getRecentProducts();
//$products = [];
?>

<div id="product_list">
  <h1>Recent Products</h1>
  <?php if (is_array($products) && count($products)) { ?>
    <?php foreach($products as $product) { ?>
      <div>
    product
      </div>
    <?php } ?>
  <?php } ?>
</div>

The error I get is: 2015-11-02T08:53:55+00:00 ERR (3): Notice: Undefined variable: this­ in /var/www/html/magento/app/design/frontend/smartwave/granada/template/recentproducts/recentproducts.phtml on line 2

Does anyone have an idea why this error occurs?

You can't use $this if you're not inside a class. You have to create an instance of AAA_Recentproducts_Block_Recentproducts and call the function on that object.

$object = new AAA_Recentproducts_Block_Recentproducts();
$products = $object->getRecentProducts();

I wouldn't recommend the variable name $object, but i can't think of a better one right now. You get the point.
