This article brings the content is about a php7+mongodb three-party introduction, there is a certain reference value, the need for friends can refer to, I hope to help you.

The project was upgraded to PHP7 due to project needs. However, after upgrading, it was found that the MONGO extension was not available. php7.0 above only supports MongoDB extension. The use of MongoDB extension drivers is more complex and verbose than the Monmgo extension. On the internet for a long time. Finally found a relatively concise MongoDB class. Grammar is similar to MONGO. Clear, Natural.

Project Address Https://github.com/mongodb/mongo-php-library

Because the project is the contribution of foreign friends. So there is no clear document to see. Here are some common ways to do this.

Get instance

$uri = "Mongodb://username:password@host/database"; $client = new \mongodb\client ($uri);

Get collection

$collection = $client->selectcollection (' Test ', ' test ');

Get a piece of data

$data = $collection->findone ([' ID ' =>1]);

Get more than one piece of data

$where = [' type ' =>1]; $options = array ('    projection ' = = Array (' id ' = = 1, ' age ' = 1, ' name ' = 1),//refers to  Returns which field 1 means return-1 means no return    ' sort ' = = Array (' id ' =-1),//Specifies the sort field    ' limit ' = = 10,//Specifies the number of bars returned    ' skip ' = 0,//specify starting position); $data = $collection->find ($where, $options)->toarray (); Var_dump ($data);

Go heavy

$fileName = ' name '; $where = [' id ' = = [' $lt ' = +]] $ret = $this->collection->distinct ($fileName, $where);

Insert a piece of data

$data = Array (    ' id ' = = 2, ' age ' = '    ,    ' name ' = ' Zhang San '); $ret = $collection->insertone ($data); $id = $ret->getinsertedid ();

BULK INSERT

$data = Array (    [' id ' = = 1, ' age ' = +, ' name ' = ' 1xiaoli '],    [' id ' = + 2, ' age ' = +, ' name ' = = ' 2xiaoli ',    [' id ' = + 3, ' age ' = ' + ', ' name ' = ' 3xiaoli '],    [' id ' = + 4, ' age ' = ' + ', ' name ' = ' 4xiaoli '],    [' id ' = 5, ' age ' = ' + ', ' name ' = ' 5xiaoli '],    [' id ' = + 6, ' age ' = +, ' name ' = ' 6x ' Iaoli '], $ret = $collection->insertmany ($data); # Return to insert Idvar_dump ($ret->getinsertedids ());

Update an article

$ret = $collection->updateone (array (' id ' = 2), array (' $set ' = = Array (' age ' = 56));

Updating multiple lines

$ret = $collection->updatemany (array (' id ' = = [' $gt ' + 1]), array (' $set ' = = Array (' age ' = ') ', ' name ' = ' x '));

Delete a bar

$ret = $collection->deleteone (array (' id ' = 2));

Delete multiple strips

$collection->deletemany (Array (' id ' = = Array (' $in ' = = = Array (1, 2)));

Polymerization

$ops = [    [        ' $match ' =>[' type ' =>[' $in ' =>[2,4]]]    ,    [        ' $sort ' = = [' List.create_time ' = >-1]  //sort order can not change, otherwise it will cause sorting confusion, attention first sort and then pagination    ],    [        ' $skip ' = 0    ],    [        ' $limit ' + = 20000    ], $data = $collection->aggregate ($ops), foreach ($data as $document) {    var_dump ($document);}
