在mysql中插入多行(用逗号分隔的项目) [英] Insert multiple rows into mysql (items separated by comma)

问题描述

我有一个小问题:)我正在网上搜索，但未找到任何解决方案.

I have a small problem :) I was searching the web but didn't find any solutions.

我有一个像这样的值(从$ _GET []中获取)

I have a value like this (got it from $_GET[])

tag1，tag2，tag3，tag4

tag1, tag2, tag3, tag4

所有我想做的就是像这样将其插入MySql(通过PHP):

and all I want to do is insert it into MySql (via PHP) like this:

+---------+-------------+
|      id |         tag |
+---------+-------------+
|      33 |        tag1 |
|      33 |        tag2 |
|      33 |        tag3 |
|      33 |        tag4 |
+---------+-------------+

我在Stack Overflow上找到了很多与此有关的文章，但是这里最大的问题是我不知道每次都会获得多少值(我没有找到答案).

I found many articles about this on Stack Overflow but the biggest problem here is that I don't know how many values I'm gonna get each time (I did not find that answer).

我将不胜感激.

推荐答案

来自英国的问候:)
您不能只遍历querystring字段并一次向数据库添加一行吗?

Hi greetings from UK :)
Can't you just loop through the querystring fields and add one row to the database at a time?

例如

<?php

$id = 33;
$value_list = 'tag1,tag2,tag3,tag4';
$values = explode(',', $value_list);
foreach ($values as $value)
{
    $sql = "INSERT INTO table (id, value) VALUES ($id, '$value');";
    //.. execute SQL now
    echo '<p>' . $sql . '</p>';
}

?>
