创建数据表:
create table serial_number(
id int primary key auto_increment not null,
serial_number varchar(50) not null
)ENGINE=InnoDB DEFAULT CHARSET=utf8
php代码如下:
$conn = mysql_connect('127.0.0.1','root','') or die("Invalid query: " . mysql_error())
mysql_select_db('test', $conn) or die("Invalid query: " . mysql_error())
$content = file_get_contents("serial_number.txt")
$contents= explode(",",$content)//explode()函数以","为标识符进行拆分
foreach ($contents as $k =>$v)//遍历循环
{
$id = $k
$serial_number = $v
mysql_query("insert into serial_number (`id`,`serial_number`)
VALUES('$id','$serial_number')")
}
备注:方法有很多种,我这里是在拆分txt文件为数组后,然后遍历循环得到的数组,每循环一次,往数据库中插入一次。
再给大家分享一个支持大文件导入的

第一步,读取txt的文件。假设为a.txt$content = file_get_content('a.txt')//读取文件内容存入变量。
第二步,存入数据库
mysql_query("insert 表名 (字段名) values('".$content."'))
Ps:文件是上传的,上传后的临时文件名是:$_FILE['tmp_name']
//记录返回值
$write_data_a = [
'html_url' => $getUrl,
'ip' =>$this->get_real_ip(),
'time' => date("Y-m-d H:i:s",time()),
