如何利用php读取txt文件再将数据插入到数据库

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

?php

$end = "')";

$sqldata = trim(file_get_contents($file));

if(preg_replace('/\s*/i','',$splitChar) == '') {

$splitChar = '/(\w+)(\s+)/i';

$replace = "$1','";

Q1: PHP中怎样把表单单选按钮的值写入数据库中

p代码中获取表单中单选按钮的值：（单选按钮只能让我们选择一个，这里有一个“checked”属性，这是用来默认选取的，我们每次刷新我们的页面时就默认为这个值。）

例：form name="myform" action="" method="post"

性别:

input type="radio" name="sex" value="男" checked /男input name="sex" type="radio" value="女" /女

input type="submit" name="submit" value="提交" /

/form

?php

echo "您的选择是：";

echo $_POST["sex"];

如果你选择的是男，则出来的值就是“男”，要是你选择的是女，则出来的值就是“女”。
