Question

我是PHP的新手。任何人都可以告诉我如何在foreach之外访问foreach循环变量。请在下面按代码查找。

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

我在以下html img标签的src属性中需要它。

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

首先定义循环上面的变量

$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

在foreach循环PHP之外访问变量
