Common functions of the PHP operation MongoDB

Connect to MongoDB:

$MONGOOBJ New Array (                        ' connect ' = =true,                        ' persist ' =true                    ));

Select a library:

$mongoDB $mongoObj->selectdb ("Wxdata");

Select a collection:

$mongoColletion=$mongoDB->selectcollection ("Apachelog");

To delete a collection:

$mongoColletion->drop ();

Insert document data:

$mongoColletion->insert (array("FirstName" = "Bob", "LastName" and "Jones"));

To modify the updated document data:

$newdata=Array(' $set ' =Array("Address" = "1 Smith Lane"));$mongoColletion->update (Array("FirstName" = "Bob"),$newdata);$mongoColletion-Update (Array("uri" = "/summer_pics"),Array(' $inc ' =Array("page hits" = 1)),Array("Upsert" =true)    );$mongoColletion-Update (Array("Name" = "Joe"),Array("username" = "joe312", "createdat" + =NewMongodate ()),Array("Upsert" =true)    );$today=Array(' $gt ' =NewMongodate (), ' $lt ' =NewMongodate (Strtotime("+1 Day")));$mongoColletion-Update (Array("Birthday" =$today),Array(' $set ' =Array(' Gift ' =$surprise)),Array("Multiple" =true)    );

New Document data:

$obj Array (' x ' = 1); $mongoColletion->save ($obj); $obj [' foo '] = ' bar '; // $obj cannot be inserted again, resulting in duplicate _id error//$mongoColletion->insert ($obj); $mongoColletion->save ($obj);

To remove a document data:

$mongoColletion->remove (arrayarraytrue));

Number of statistical documents:

$mongoColletion,count(array(' Httpstatus ' =>304));

To query a document:

$mongoColletion->findone (array("httpstatus" = 200));

To view document index information:

$mongoColletion->getindexinfo ();

To build a document index:

//Create an index on ' httpstatus ' ascending$mongoColletion->ensureindex (Array(' httpstatus ' = 1));//Create a unique index on ' size '$mongoColletion->ensureindex (Array(' size ' = 1),Array(' unique ' =true));//Create a compound index on ' size ' ascending and ' status ' descending$mongoColletion->ensureindex (Array(' Size ' = 1, ' status ' = 1));//Full-Text indexing$mongoColletion-Ensureindex (Array(            ' Title ' = ' text ', ' desc ' = ' text ',        ),Array(            ' Name ' = ' exampletextindex ', ' weights ' =Array(                ' title ' = +, ' desc ' = 30,            )        )    );

Close the connection to MongoDB:

$mongoObj->close ();

There are so many functions that you can use from PHP to manipulate MongoDB.
