php - 循环通过批处理 Codeigniter

问题描述

我正在使用insert_batch()函数将数据插入数据库。

我想拆分这个过程。我的意思是，如果我想创建 10,000 个序列号。但是一次 1,000 行，它应该循环运行创建过程 10 次。

我怎样才能做到这一点？

    $serial_numbers  = $this->serial_numbers_model->generate_serial_numbers($product_id, $partner_id, $serial_number_quantity, $serial_number_start);
    $issued_date     = date("Y-m-d H:i:s");
    $inserted_rows   = 0;

    foreach ($serial_numbers as $sn) {
        $check_number = $this->serial_numbers_model->generate_check_number();
        $first_serial_number = reset($serial_numbers);
        $last_serial_number = end($serial_numbers);
        $inserted_rows++;

        $insert_data[] = array(
            'partner_id'            => $partner_id,
            'product_id'            => $product_id,
            'check_number'          => $check_number,
            'serial_number'         => $sn,
            'issued_time'           => $issued_date,
            'serial_number_status'  => CREATE_STATUS
        );
    }

    $this->serial_numbers_model->insert_batch($insert_data);
}

解决方案

可能您serial_numbers_model->insert_batch()的只是 Codeigniter 原生的包装器insert_batch()？为了清楚起见，下面的代码使用本机代码，根据需要将其替换为您的代码。

// Track how many in your batch, and prepare empty batch array
$count = 0;
$insert_data = [];

foreach ($serial_numbers as $sn) {

    // ... your code, prepare your data, etc ...

    $count++;

    $insert_data[] = array(
        // ... your data ...
    );

    // Do you have a batch of 1000 ready?
    if ($count === 1000) {

        // Yes - insert it
        $this->db->insert_batch('table', $insert_data);
        // $this->serial_numbers_model->insert_batch($insert_data);

        // Reset the count, and empty the batch, ready to start again
        $count = 0;
        $insert_data = [];
    }
}

// Watch out!  If there were 1001 serial numbers, the first 1000 were handled, 
// but the last one hasn't been inserted!
if (sizeof($insert_data)) {
    $this->db->insert_batch('table', $insert_data);
}
