Php Magento批量订单、产品和客户创建

Php Magento批量订单、产品和客户创建,php,magento,memory-management,memory-leaks,Php,Magento,Memory Management,Memory Leaks,我在Magento中创建了一个模块,通过创建随机的产品、订单和客户来复制大型商店。上面描述的数据创建发生在我的模型中,该模型是纯PHP代码。尽管使用了PHP的unset()和Magento的clearInstance(),我还是遇到了严重的内存管理问题。我在下面注释了10行代码,显示了我释放内存的尝试是如何失败的 /** * Creates random customers. * * @param int $offset, used to make sure the ids create

我在Magento中创建了一个模块,通过创建随机的产品、订单和客户来复制大型商店。上面描述的数据创建发生在我的模型中,该模型是纯PHP代码。尽管使用了PHP的unset()和Magento的clearInstance(),我还是遇到了严重的内存管理问题。我在下面注释了10行代码,显示了我释放内存的尝试是如何失败的

/**
 * 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代替clearInstance()会产生相同的结果。关于使用Magento型号后如何清理的任何提示?

我会使用资源而不是型号,这样会更快、内存成本更低。如果这还不够好,请将其转换为原始sql,EAV在插入记录时并没有那么复杂

我还想尝试的另一种方法是: 但这不建议用于生产,所以我将构建一个包含这些解构师的自定义客户模型,并在脚本中使用新模型,而其他所有(生产)都在正常模型上运行
