TP5 of thinkPHP5 Framework mongodb Extension Installation and Special Operation Examples

This article illustrates the TP5 (thinkPHP5) framework mongodb extension installation and special operations. Share it for your reference, as follows:

ThinkPHP 5.0 MongoDb Drive

First install the official mongodb extension:

http://pecl.php.net/package/mongodb

Find the extension of the corresponding php version

Then, the type parameter of the database configuration file database. php for the configuration application is:

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

You can use MongoDb normally, for example:

Use the latest mongodb extensions

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

Or use model operations:

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

The default primary key of MongoDb is _ id and is an ObjectID object. If you want to use id as the primary key like mysql1, you can use the following parameters:

//  Forcibly put _id Convert to id
'pk_convert_id' => true,

tp5 Mongodb Special Operation

Push operation

Add data

public function add(){
    $this->data = [
      ' Author '  => 'tuzi',
      ' Age '  => '22',
      ' Title '  => ' Defense tower and replenishment of troops ',
      ' Comments '  => [
        [
          ' Serial number '  => '001',
          ' Content '  => '5 Kill '
        ]
      ]
    ];
    $res = Db::table('document')->insert($this->data);
    if($res){
      echo "success";
    }else{
      echo "error";
    }
}

Results

array(1) {
[0] = > array(5) {
["_id"] = > object(MongoDB\BSON\ObjectId)#12 (1) {
["oid"] = > string(24) "5a51f73083869e4b65549c36"
}
["Author"] = > string(4) "tuzi"
["Age"] = > string(2) "22"
["Title"] = > string (15) "Anti-tower and Replenishment"
["Comment"] = > array(1) {
[0] = > array(2) {
["Serial number"] = > string(3) "001"
["Content"] = > string (6) "5 Kills"
}
}
}
}

Update data with push

public function update()
{
    $update_data[' Comments '] = [
      '$push',
      [
        ' Serial number '  => '002',
        ' Content '  => '3 Kill '
      ]
    ];
    $update_res = Db::table('document')->where(' Title ',' Defense tower and replenishment of troops ')->update($update_data);
    if($update_res){
      echo "success";
    }else{
      echo "error";
    }
}

Results

array(1) {
[0] = > array(5) {
["_id"] = > object(MongoDB\BSON\ObjectId)#12 (1) {
["oid"] = > string(24) "5a51f73083869e4b65549c36"
}
["Author"] = > string(4) "tuzi"
["Age"] = > string(2) "22"
["Title"] = > string (15) "Anti-tower and Replenishment"
["Comment"] = > array(2) {
[0] = > array(2) {
["Serial number"] = > string(3) "001"
["Content"] = > string (6) "5 Kills"
}
[1] = > array(2) {
["Serial number"] = > string(3) "002"
["Content"] = > string (6) "3 Kills"
}
}
}
}
