填写好数据库相关操作后,点击下一步,首先将数据库连接起来
12mysql_connect(..............)//等等这些数据库连接代码
数据库连接后,开始读取sql文件
1234567$Sqls = file_get_contents( '你的sql文件' );//然后把读取到的sql文件内容打散成数组,当然,这个文件要有规律,就是每条sql语句有一个特定的分隔符,比如分号;$SqlArr = explode(';', $Sqls );//最后就是循环遍历出这些sql语句并执行,即可foreach ( $SqlArr as $sql ) { mysql_query( $Sql );}
上面只是一个大致思路原理,
具体的话,还是要根据具体情况来弄的!
特别是那个sql文件中的内容,一定要有一定的规律,并且一些不必要的东西不能有,
比如注释(很多人从phpmyadmin导出的sql文件,都会带上注释,
而注释是不符合sql语句规范的,会执行出错,
所以导出后,自己根据情况修改一下!)
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
