I mentioned the database connection operation earlier, please refer to: mongodb detailed explanation of adding users and permission settings
Operations on the database: please refer to: mongodb detailed explanation of database operations--create, switch, delete
Let’s talk about the insertion operation of the database table
1. Insert operation under the command line

> use test;    #切换到test数据库 
switched to db test
  
> document=({"title" : "linux命令", "auther" : "tank" });   #定义了一个变量 
{ "title" : "linux命令", "auther" : "tank" } 
> db.test.insert(document);     #插入变量 
> db.test.find();       #查看插入的数据 
{ "_id" : ObjectId("53c8fc1cf062ac30ee8b9d2d"), "title" : "linux命令", "auther" : "tank" } 
  
> db.test.insert({"title" : "51yip", "auther" : "tank" });  #直接插入数据 
> db.test.find();       #查看 
{ "_id" : ObjectId("53c8fc1cf062ac30ee8b9d2d"), "title" : "linux命令", "auther" : "tank" } 
{ "_id" : ObjectId("53c8f6fff062ac30ee8b9d2e"), "title" : "51yip", "auther" : "tank" }
Copy after login

2. Use php to expand insert data

<?php 
  
//$mongo = new Mongo("mongodb://192.168.10.202:27017"); //链接远程数据库 
$mongo = new Mongo();          //链接远程数据库 
$curDB = $mongo->selectDB("test");    //选择要操作的数据库,如果不存在,则自动创建 
$collection = $curDB->selectCollection("test"); //选中一个集合(理解为 table),如果不存在,则自动创建 
//$collection->drop();       //清空集合 testCollection 
  
$count = $collection->count();     //查看集合中的数据量 
echo "insert前集合中有[".$count."]条数据<Br>";  //这里的二条数据主命令行下插入的。 
  
echo "<br>********** mongodb php insert 插入 *************<br>"; 
  
$obj = array("title"=>"围城","auther"=>"钱钟书"); 
$rel = $collection->insert($obj); 
var_dump($rel);         //打印插入后的结果是bool型的 
echo "<Br>新增对象的id:".$obj[&#39;_id&#39;]."<Br>"; 
  
$obj = array("title"=>"朝发白帝城","auther"=>"李白"); 
$rel = $collection->insert($obj,array(&#39;safe&#39;=>true)); //safe 表示是否返回操作结果信息,返回的信息为 array 
print_r($rel);         //插入后的结果是数组 
echo "<Br>新增对象的id:".$obj[&#39;_id&#39;]."<Br>";; 
  
$count = $collection->count();     //查看集合中的数据量 
echo "insert后集合中有[".$count."]条数据<Br>"; 
  
?>
Copy after login

Running results:
There are [2] pieces of data in the collection before insert

********** mongodb php insert Insert *************
bool(true)
The id of the new object: 53c908c87f8b9ad7218b4568
Array ( [n] => 0 [connectionId] => 4 [err] => [ok] => 1)
The id of the new object: 53c908c87f8b9ad7218b4569
There are [4] pieces of data in the collection after insert
