foreach循环之外的访问变量PHP

Question

我是PHP新手。任何人都可以告诉我如何访问foreach之外的foreach循环变量。请按代码在下面找到。

<?php $categories = Mage::getModel('catalog/category')->getCollection()->addAttributeToSelect('*'); 
     foreach ($categories as $category): 
     $categorySize = $category->getSize_chart(); 
     print_r ($categorySize); 
     endforeach; 
    ?> 

我需要它在以下HTML img标签的src属性。

<div class="SizeChat"><p>close</p><div class="Padd"><img src="<?php echo Mage::getBaseUrl('media').'catalog/category/'.$categorySize ?>"></div></div> 

Answer 1

首先定义上述环

$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
