[英]can't insert json data into mysql database in php
I have a json format data without key value pair. 我有一个没有键值对的json格式数据。 when i insert data my table only the 1st data is inserted(of the array).
当我在表中插入数据时,仅插入(数组的)第一数据。 how i insert the all data into my databse table?
我如何将所有数据插入我的数据库表?
<?php
$mysqli = new mysqli('localhost','root','','user');
$my_json_data = file_get_contents('./jason_data.txt');
$my_data = json_decode($my_json_data,true);
foreach($my_data as $data){
$sql = "INSERT INTO demo_table (data) VALUES ('$data');";
$mysqli->query($sql);
}
echo "done...";
?>
my database table name is 'demo_table' and json data fromat like this 我的数据库表名称是'demo_table'和这样的json数据
["hello-world","sample-page","privacy-policy","2-revision-v1","the-banner-title"]
which is a .txt format in the same directory of my workspace 这是我工作区同一目录中的.txt格式
my table schema is like this 我的表架构是这样的
CREATE TABLE `demo_table` (
`id` int(5) NOT NULL,
`data` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
Seems you have not a proper primary key. 似乎您没有正确的主键。
Try create in the demo_table a proper primary key based on auto increment column 尝试在demo_table中基于自动增量列创建正确的主键
based on your schema add autoincrement 根据您的架构添加自动增量
CREATE TABLE `demo_table` (
`id` int(5) NOT NULL AUTO_INCREMENT,
`data` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
in this each row inserted have a automatic different primary key .. otherwise the first insertion create an id = 0 and the second try to do the same ..but 0 already exist 在此插入的每一行都有一个自动的不同主键..否则,第一次插入创建一个id = 0,第二次尝试执行相同的操作..但已经存在0
