創(chuàng)建數(shù)據(jù)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代碼如下：
$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()函數(shù)以","為標(biāo)識符進(jìn)行拆分
foreach ($contents as $k = $v)//遍歷循環(huán)
{
$id = $k;
$serial_number = $v;
mysql_query("insert into serial_number (`id`,`serial_number`)
VALUES('$id','$serial_number')");
}
備注：方法有很多種，我這里是在拆分txt文件為數(shù)組后，然后遍歷循環(huán)得到的數(shù)組，每循環(huán)一次，往數(shù)據(jù)庫中插入一次。
再給大家分享一個支持大文件導(dǎo)入的

fopen讀取txt文件的內(nèi)容，返回字符串，把它存入一個變量，再把變量值存入數(shù)據(jù)庫?？梢钥纯催@個函數(shù)
第一步，讀取txt的文件。假設(shè)為a.txt
$content = file_get_content('a.txt'); //讀取文件內(nèi)容存入變量。
第二步，存入數(shù)據(jù)庫
mysql_query("insert 表名 (字段名) values('".$content."'));
Ps：文件是上傳的，上傳后的臨時文件名是：$_FILE['tmp_name']
