Basic tutorial on operating MongoDB in PHP (connection, addition, modification, deletion, query)_PHP

MongoDB

The code is as follows:
//Connect localhost:27017
$cOnn= new Mongo();

//Default port for connecting to the remote host
$cOnn= new Mongo(‘test.com’);

//Connect to the remote host port 22011
$cOnn= new Mongo(‘test.com:22011’);

//MongoDB has a username and password
$cOnn= new Mongo(“mongodb://${username}:${password}@localhost”)

//MongoDB has a username and password and specifies the database blog
$cOnn= new Mongo(“mongodb://${username}:${password}@localhost/blog”);

//Multiple servers
$cOnn= new Mongo(“mongodb://localhost:27017,localhost:27018”);
//Select database blog
$db = $conn-> blog;
//Specify the result set (table name: users)
$collection = $db->users;
//Newly added
$user = array(‘name’ => ‘caleng ‘, ’email’ => ‘admin#admin.com’);
$collection->insert($user);
//Modify
$newdata = array(‘$set’ => array (“email” => “test@test.com”));
$collection->update(array(“name” => “caleng”), $newdata);
//Delete
$collection->remove(array(‘name’=>’caleng’), array(“justOne” => true));
//Find
$cursor = $collection->find();
var_dump($cursor);
//Find one
$user = $collection->findOne(array(‘name’ => ‘caleng’), array(’email’));
var_dump($user);
//Close the database
$conn->close();
