如何循环Magento集合?

问题描述:

基本上,我需要获取我的客户的CSV文件,每天在脚本中自动生成。 我尝试了几种方法,但它们太慢或实际上已经耗尽内存。如何循环Magento集合?

* 1)通过收集资源*

$collection = Mage::getResourceModel('customer/customer_collection') 
->addAttributeToSelect('email') 
->addAttributeToSelect('created_at') 
->joinAttribute('billing_company', 'customer_address/company', 'default_billing', null, 'left') 
->joinAttribute('billing_street', 'customer_address/street', 'default_billing', null, 'left') 
->joinAttribute('billing_postcode', 'customer_address/postcode', 'default_billing', null, 'left') 
->joinAttribute('billing_telephone', 'customer_address/telephone', 'default_billing', null, 'left') 
->joinAttribute('billing_city', 'customer_address/city', 'default_billing', null, 'left') 
->joinAttribute('billing_region', 'customer_address/region', 'default_billing', null, 'left') 
->joinAttribute('billing_country_id', 'customer_address/country_id', 'default_billing', null, 'left'); 

foreach($collection as $customer) { 
echo $customer->getFirstname() . ","; 
} 

2)的foreach和负载客户

$collection = Mage::getResourceModel('customer/customer_collection'); 
foreach($collection as $customer) { 
    $fullcustomer = Mage::getModel("customer/customer")->load($customer->getId()); 
    echo $fullcustomer->getFirstname() . ","; 
} 

任何想法的foreach?

谢谢!

这两项解决方案似乎可行,但双方似乎特别优化。你能否用这两种方法解决问题,以便我们可以告诉你在找什么? – 2010-09-24 13:35:55

尝试在Magento中使用资源迭代器。看到这个职位:http://stackoverflow.com/questions/7419886/using-magentos-resource-iterator-model-on-a-product-collection – awaage 2012-09-15 02:27:06

在每个Customer对象上使用load()将显着减少减慢您的代码。我建议你添加所需的属性集合的第一种方法是正确的,但像完成它:

$collection->toArray([$arrRequiredFields = array()]); 

这样一来,个人客户不会被装载,但toArray()doco here)将给你你想要的字段,然后你可以迭代多维数组来产生你的逗号分隔的字符串。

或者,您可以尝试$collection->toXml()并使用XML,如果您对此感到满意。 Google会将您指向xml-> csv转换方法。

恐怕我得到了空白页面用尽了内存.. 。 – 2010-09-29 16:32:51

尝试分页大集合!

这个想法是,如果你可以加载更小的块集合,你将不会使用尽可能多的内存。 加载一个块(页面),然后对其进行处理,如将其保存到文本文件中,然后加载下一个块。结果是,你已经与整个较大的集合一起工作,但只会产生最大页面的内存成本。

我们使用类似的东西来从我们的商店导出订单。 我插入你的收藏,它似乎工作。

    $pages = $collection->getLastPageNumber(); 
    $currentPage = 1; 
    //This is the file to append the output to. 
    $fp = fopen('/tmp/customers.csv', 'w'); 
    do{ 
     //Tell the collection which page to load. 
     $collection->setCurPage($currentPage); 
     $collection->load(); 
     foreach ($collection as $customer){ 
      //write the collection array as a CSV. 
      $customerArray = $customer->toArray(); 
      //var_dump($customerArray); echo "\n\n"; 
      fputcsv($fp, $customerArray); 
      $customerCount++; 
     } 
     $currentPage++; 
     //make the collection unload the data in memory so it will pick up the next page when load() is called. 
     $collection->clear(); 
    } while ($currentPage <= $pages); 
    fclose($fp); 
} catch (Exception $e) { 
    //$response['error'] = $e->getMessage(); 
    Mage::printException($e); 
} 
echo "Saved $customerCount customers to csv file \n"; 
?> 

我救它作为exportCustomers.php。

然后设置你的cron任务运行: PHP -f /path/to/your/magento/exportCustomers.php
