ThinkPHP 5.0 MongoDb驱动文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/8860.html

首先安装官方的mongodb扩展：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/8860.html

找到对应的php版本的扩展文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/8860.html

然后，配置应用的数据库配置文件database.php的type参数为：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/8860.html

'type' => '\think\mongo\Connection',

即可正常使用MongoDb，例如：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/8860.html

使用最新mongodb扩展文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/8860.html

Db::name('demo')
  ->find();
Db::name('demo')
  ->field('id,name')
  ->limit(10)
  ->order('id','desc')
  ->select();

或者使用模型操作：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/8860.html

User::get(1);
User::all('1,2,3');

MongoDb默认的主键是_id并且是一个ObjectID对象，如果需要和mysql一样使用id作为主键，可以如下参数：文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/8860.html

// 强制把_id转换为id
'pk_convert_id' => true,

添加数据文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/8860.html

public function add(){
    $this->data = [
      '作者'  => 'tuzi',
      '年龄'  => '22',
      '标题'  => '防塔与补兵',
      '评论'  => [
        [
          '序号'  => '001',
          '内容'  => '五杀'
        ]
      ]
    ];
    $res = Db::table('document')->insert($this->data);
    if($res){
      echo "success";
    }else{
      echo "error";
    }
}

结果文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/8860.html

array(1) {
[0] => array(5) {
["_id"] => object(MongoDB\BSON\ObjectId)#12 (1) {
["oid"] => string(24) "5a51f73083869e4b65549c36"
}
["作者"] => string(4) "tuzi"

["内容"] => string(6) "五杀"
}
}
}

利用push更新数据文章源自菜鸟学院-https://www.cainiaoxueyuan.com/bc/8860.html

public function update()
{
    $update_data['评论'] = [
      '$push',
      [
        '序号'  => '002',
        '内容'  => '三杀'
      ]
    ];
    $update_res = Db::table('document')->where('标题','防塔与补兵')->update($update_data);
    if($update_res){
      echo "success";
    }else{
      echo "error";
    }
}
