Hello目前我有一个MYSQL数据库，我在其中发布表单数据。然后我使用PHP来回显数据并查看表单信息。最近我添加了一个复选框，复选框的值存储为ARRAY。当我回到我的数据库时，我得到的输出是
名称，日期，阵列，阵列
我没有得到ARRAY这个词，而是想获得提交的价值。我知道你应该使用implode命令，但我无法想出一种方法将它合并到我的代码中。检索代码如下所示。使用field_10，field_11，field_12只返回单词ARRAY。

表单处理代码是这个
<?php
$where_form_is="http://".$_SERVER['SERVER_NAME'].strrev(strstr(strrev($_SERVER['PHP_SELF']),"/"));
include("config.inc.php");
$link = mysql_connect($db_host,$db_user,$db_pass);
if(!$link) die ('Could not connect to database: '.mysql_error());
mysql_select_db($db_name,$link);

无法在MySQL数据库中存储PHP数组（因为它的类型），但您可以将其转换为字符串并存储它。当然，您可以稍后将此字符串转换回数组。您应该更改数据库字段以键入var request = require('request');
var url = 'https://www.example.com/api/';
var data = {
"jsonrpc":"2.0",
"id":"3"
};
request.post({url:url, formData: data}, function(err, httpResponse, body) {
if (err) {
return console.error('post failed:', err);
}
console.log('Post successful! Server responded with:', body);
});
以在其中存储数组。
要以文本形式存储数组，您可以使用LONGTEXT：
serialize或者使用JSON（在数据库中更好的可读性）：
$arr = serialize($arr); // To save it in DB
$arr = unserialize($arr); // To get array after select

嘿伙计们我只是想发布完整的代码包装，其他人都遇到了麻烦。我将序列化函数添加到我的表单处理部分。
everyWhere奇怪的是，当你反序列化它时。它只是再次输出单词数组。
