如何使用 php 将多个字段数据存储到同一个变量中？
How to store multiple fields data into same variable using php?
我是 PHP 的新手。我有一个使用 input type text 的表格，现在我想将多个字段数据存储到 mysql 数据库的同一列中。
例如，根据上图，我想将所有意见存储在一列中，将所有评级类型存储在一列中等等。
我在谷歌上搜索了这个问题，我发现 implode 是解决方案。但是不知道怎么用。

你能帮帮我吗？
你可以像下面这样使用 implode
$users = [
"Andrew",
"Max",
"Larry",
"Ricardo",
"Lucy",
"Marcus",
"Sophie"
];
print_r(implode('-',$users));
但你必须先将所有值放入数组中，然后使用内爆生成不同的值以形成一个字符串以存储在数据库中。当你想使用这个值时，你必须爆炸。这样，您只能使用一列。
既然已经有人说过您正在尝试做的事情会违反 FNF (First Normalization Form) 并且显然您偏离了正轨。我的建议是制作一个 <form> 然后使用它的值存储在你的数据库中（尽可能多而不违反任何规则）
示例如下：
<?php
//apply all your checks
//fetching the data
$opinion = $_POST['opinion'];
$rating_type = $_POST['rating_type'];
$action = $_POST['action'];
$outlook = $_POST['outlook'];
//Insert into your database
$que = "INSERT INTO table(opinion, rating_type, action, outlook) Values ('$opinion','$rating_type','$action','$outlook')";
$run = mysql_query($que);
if($run) echo "DATA ENTERED!";
<form method = "POST" action = "">
<label>Opinion</label>
<input type = "text" name = "opinion">
<label>Opinion</label>
<input type = "text" name = "rating_type">
<label>Opinion</label>
<input type = "text" name = "action">
<label>Opinion</label>
<input type = "text" name = "outlook">
//for as much you want...
<input type = "submit" name = "sub">
</form>
这将使您可以在数据库中输入任意多的数据，当您想查看记录时，只需创建一个并应用 SELECT 查询，它就会显示所有记录。
