Php Json到mysql数据库转换

php mysql json database

Php Json到mysql数据库转换,php,mysql,json,database,Php,Mysql,Json,Database,我在一个类中有一个项目，用数据库创建一个图库重要的部分是背景本身我下载了一个非常酷的图库，但是图像集成是一个json文件 [{ "lowsrc": "thumbnails\/1.jpg", "fullsrc": "full\/1.jpg", "description": "Zweifellos Mondbetont", "category": "photography" }, { "lowsrc": "thumbnails\/2.jpg", "

我在一个类中有一个项目，用数据库创建一个图库重要的部分是背景本身

我下载了一个非常酷的图库，但是图像集成是一个json文件

[{
    "lowsrc": "thumbnails\/1.jpg",
    "fullsrc": "full\/1.jpg",
    "description": "Zweifellos Mondbetont",
    "category": "photography"
}, {
    "lowsrc": "thumbnails\/2.jpg",
    "fullsrc": "full\/2.jpg",
    "description": "Mehmet Dere",
    "category": "drawing"
}, {
    "lowsrc": "thumbnails\/3.jpg",
    "fullsrc": "full\/3.jpg",
    "description": "Samantha Keely Smith",
    "category": "drawing"
}, {
    "lowsrc": "thumbnails\/4.jpg",
    "fullsrc": "full\/4.jpg",

是否可以将其转换为使用mysql数据库？如何实现呢？

简单地说，只需将JSON对象转换为数组，然后遍历即可构建插入查询：

SQL:

CREATE TABLE `gallery` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `lowsrc` varchar(255) DEFAULT NULL,
  `fullsrc` varchar(255) DEFAULT NULL,
  `description` text,
  `category` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

<?php
    $json = '
        [{
            "lowsrc": "thumbnails\/1.jpg",
            "fullsrc": "full\/1.jpg",
            "description": "Zweifellos Mondbetont",
            "category": "photography"
        }, {
            "lowsrc": "thumbnails\/2.jpg",
            "fullsrc": "full\/2.jpg",

        }, {
