推荐答案
首先在循环上方定义变量
First define the variable above of the loop
$categorySize = array();
<?php $categories = Mage::getModel('catalog/category')->getCollection()->addAttributeToSelect('*');
foreach ($categories as $category):
$categorySize = $category->getSize_chart();
print_r ($categorySize);
endforeach;
?>
print_r($categorySize) //Now you can get it outside the loop
