今天测试一个功能，需要往数据库中插入一些原始数据，PM给了一个txt文件，如何快速的将这个txt文件的内容拆分为所要的数组，然后再插入到数据库中？
serial_number.txt的示例内容：
serial_number.txt：
DM00001A11 0116, SN00002A11 0116, AB00003A11 0116, PV00004A11 0116, OC00005A11 0116, IX00006A11 0116,
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
