The biggest advantage of Mongo DB is that all data persistence operations can easily implement C
turn off MongoDB services?[[email protected] bin]$ sudo pkill mongod[sudo] password for Neil: [[email protected] bin]$ pstree-p| grep mongod[[email protected] bin]$In this way, the MONGDB is closed with the Pkill command. You can also use kill--all here.Note: But you can not use kill-9 to close MongoDB, otherwise you will find the next time can not successfully start Mongod!!! Remember!!!__________________

Detailed examples of PHP operations on MongoDB (add, delete, modify, and query) (6) PHP operations on mongodb:
Modules are required for PHP to operate mongodb.
Official website can download: http://pecl.php.net/package/mongo download
Set mongodb to user-authorized startu
to:
db.inventory.find( { size: { h: 14, w: 21, uom: "cm" } } )
An equality match in an entire embedded document requires an exact match to the specified
For example, the following queryinventorydoes not match any of the documents in the Inventory () collection:
db.inventory.find( { size: { w: 21, h: 14, uom: "cm" } } )
Querying nested fields
To specify a query condition on a field in an embedded/nested document, use the dot symbol ("field.nestedField").
