php导入关键词的脚本 300条分批导入

关键词就一列，是txt文件格式
//导入关键词脚本
function add_keywords(){
  // 读取文件
    $filename = dirname(dirname(__DIR__)).'/keyword.txt';//获取的目录是E:\Wampee-3.1.0-beta-3.5\www\1688order\server/application/keyword.txt
    //$filename = 'keyword.txt';
    if (!file_exists($filename)) {
        die("文件不存在: $filename");
    }

    $content = file_get_contents($filename);
    $lines = array_filter(explode("\n", $content)); // 移除空行

    // 分批处理，每批300条
    $batchSize = 300;
    $chunks = array_chunk($lines, $batchSize);

    $total = 0;
    foreach ($chunks as $chunk) {
        $data = [];
        foreach ($chunk as $name) {
            // 跳过空值
            if (empty(trim($name))) {
                continue;
            }

            $data[] = [
                'name' => $name,
                'is_show' => 1,
                'status' => 1,
                'create_time' => time(),
            ];
        }

        if (!empty($data)) {
            // 批量插入
            db('keywords')->insertAll($data);
            $total += count($data);
            echo "已插入 " . count($data) . " 条记录，累计 {$total} 条\n";
        }
    }

    echo "共插入 {$total} 条记录";
