我在Magento中创建了一个模块,它通过创建随机产品,订单和客户来复制大型商店。上面描述的数据创建在我的模型中是直接的PHP代码。尽管使用了PHP的unset()和Magento的clearInstance(),但我仍然遇到严重的内存管理问题。我已经评论了〜下面的10行代码,说明我如何释放内存失败。Magento批量订单,产品和客户创建
/**
* Creates random customers.
*
* @param int $offset, used to make sure the ids created are unique
*/
protected function _createCustomer($offset)
{
// Create some random customer information
$firstName = strtolower($_firstNames[array_rand($_firstNames, 1)]);
$lastName = strtolower($_lastNames[array_rand($_lastNames, 1)]);
$customerEmail = $firstName[0] . $lastName.time().$offset."@weliketopumpit.com";
// Retrieve customer model
$customer = Mage::getModel('customer/customer')
->setWebsiteId(Mage::app()->getWebsite()->getId())
->loadByEmail($customerEmail);
// Populate model and save it
if(!$customer->getId()){
$customer
->setEmail ($customerEmail)
->setFirstname($firstName)
->setLastname ($lastName)
->setPassword ('password1')
->setCreatedAt(rand($this->_startDate, time()));
}
$customer->save();
$customer->setConfirmation(null);
$customer->save();
$this->log(memory_get_usage() . "\n"); // Returns 17306840
$customer->clearInstance(); // Called to clean up the object
$this->log(memory_get_usage()); // Returns 17307304, memory wasn't unallocated
debug_zval_dump($customer); //Returns a refcount(2)
}
调用unset而不是clearInstance()会产生相同的结果。使用Magento模型后如何清理的任何提示?
