thinkphp5.* model adds duplicate method|tp5, tp5.1 adds duplicate method

tp6 comes with the duplicate method, but some old projects using tp5 and 5.1 do not support duplicate. If we need to use duplicate at this time, we need to implement it ourselves.

<?php
namespace app\index\model;

use think\Model;

class BaseModel extends Model
{
    
    
    // 数据插入 duplicate
    public function insertAllDuplicate($data, $duplicate = null, $limit = null) {
    
    
        if (!empty($duplicate)) {
    
    
            if (is_array($duplicate)) {
    
    
                $temp = [];
                foreach ($duplicate as $key => $item) {
    
    
                    if (is_integer($key)) {
    
    
                        $temp[] = "{
      
      $item} = VALUES({
      
      $item})";
                    }
                    else {
    
    
                        $temp[] = "{
      
      $key} = {
      
      $item}";
                    }
                }
                $duplicate = implode(',', $temp);
            }
        }
        if (!empty($limit)) {
    
    
            // 分批写入 自动启动事务支持
            $this->startTrans();

            try {
    
    
                // array_chunk 函数把数组分割为新的数组块。
                //其中每个数组的单元数目由 size 参数决定。最后一个数组的单元数目可能会少几个。
                //可选参数 preserve_key 是一个布尔值，它指定新数组的元素是否有和原数组相同的键（用于关联数组），还是从 0 开始的新数字键（用于索引数组）。默认是分配新的键。
                $array = array_chunk($data, $limit, true);
                $count = 0;

                foreach ($array as $item) {
    
    
                    $sql  = $this->fetchSql(true)->insertAll($item);
                    $sql = preg_replace("/INSERT\s*INTO\s*/", "INSERT IGNORE INTO ", $sql);
                    if (is_string($duplicate)) {
    
    
                        $sql = $sql . ' ON DUPLICATE KEY UPDATE '. $duplicate;
                    }
                    $count += $this->execute($sql); // 获取影响函数
                }
                // 提交事务
                $this->commit();
            } catch (\Exception $e) {
    
    
                $this->rollback();
                throw $e;
            }
            return $count;
        }
        else {
    
    
            $sql = $this->fetchSql(true)->insertAll($data);
            $sql = preg_replace("/INSERT\s*INTO\s*/", "INSERT IGNORE INTO ", $sql);
            if (is_string($duplicate)) {
    
    
                $sql = $sql . ' ON DUPLICATE KEY UPDATE '. $duplicate;
            }
            return $this->execute($sql);
        }
    }
}

usage

// 定义产品模型
<?php
namespace app\index\model;

use think\Model;

class Product extends BaseModel
{
    
    
}
?>

// 业务代码调用
$ProductModel = new app\index\model\Product();
$dateTime = '2023-06-15 18:00:00';
$ProductModel->insertAllDuplicate([
    ['title' => 'title00000000', 'img' => 'http://img.com/0000.jpg', 'update_time' => dateTime ],
    ['title' => 'title11111111', 'img' => 'http://img.com/11111111.jpg', 'update_time' => dateTime ],

    ['title' => 'title33333333', 'img' => 'http://img.com/33333333.jpg', 'update_time' => dateTime ],
], [
    'title', // title = VALUES(title)
    'update_time' => '{$dateTime}' // update_time = '{$dateTime}'
], 2);
//sql=> INSERT IGNORE INTO `product`(`title`, `img`, `update_time`) VALUES('title00000000', 'http://img.com/0000.jpg', '2023-06-15 18:00:00'), ('title11111111', 'http://img.com/11111111.jpg', '2023-06-15 18:00:00') ON DUPLICATE KEY UPDATE title = VALUES(title), update_time = '2023-06-15 18:00:00';
