Configuration of MONGO on TP

TP already supports MongoDB database, here is a detailed description of the configuration and use of MONGO on TP.

(1) There is a bug in the original class of/think/model/mongomodel.class.php in the tp3.2.2 version. We need to add some code to the original class to fix the bug.

The above is a complete MONGO class after the modification.

which

(1)

protected $connection       =   ' Db_mongo '; is the Db_mongo (2) corresponding to the Link configuration config

  Resolve parameter $field The returned result $key incorrect if the field order specified is inconsistent with the order of the record fields in the database                //2015-08-15 by Bing                if (! ( Array_search ($_field[0], Array_keys ($resultSet [0])) (===false)) {                    $key =$_field[0];                    $key 2=$_field[1];                }

This piece is added to create a database cache

(3)

  Bing 2015-8-15 Get datasheet     if (empty ($this->dbname) &&!empty ($this->connection)) {            $db _c            $ This->dbname= $db _config[' db_name '];        }        $this->db->switchcollection ($this->gettablename (), $this->dbname);   

This function in the TP original Mongomodel will only be linked to the MySQL configuration dbname, now to make changes, as shown above.

Second, configure the Db_mongo in TP

(1) Add in config file

' Db_mongo ' =>array (' db_type ' = '   MONGO ',//database type ' db_host '   = ' localhost ',//server address ' db_name '   = > ' Test ',//database name ' Db_user ' + ',//   user name ' db_pwd ' + '    ,//password ' db_port '   = ' 27017 ',//port,

MONGO is not certified by default, so the user name and password are empty.

(2) Additions to the Mongomodel

protected $connection       =   ' Db_mongo '; is the Db_mongo of the link configuration config, which is the complete MONGO class above.

The configuration of the database is now complete.

Third, install Php_mongo drive

Installing drivers on Windows must correspond to the large version of PHP that you use.

(1) Download the corresponding version of Php_mongo.

(2) Copy the Php_mongo.dll into the PHP ext file

(3) Add Extension=php_mongo.dll to PHP.ini

(4) Restart Apache

(5) Visit phpinfo, search MONGO

The presence above represents a successful configuration.

Iv. curd operation of MONGO on TP

(1) PHP connection MONGO, creating instantiated objects

$m =new \think\model\mongomodel (' user ');

Where "User" is a collection, which is equivalent to a table in MySQL.

(2) Add--add ()

Query is basically the same as MySQL,

Example

$data =array (          "Name" = "John Doe",          "addr" and "Shenzhen",          "sex" = "male",          "info" =>array (              "Age" = "              Phone" = "12345",            )        ;

$result = $m->add ($data);

This adds the data as a document, equivalent to a record of MySQL.

(2) Inquiry--select (), GetField ()

If you want to query the $data that you just inserted,

$map [' name ']= "John Doe",

$result = $m->where ($map)->select ();

The entire document is searched, and an array is returned.

Array (5) {    ["_id"] + int (4)    ["name"] + = string (6) "John Doe"    ["addr"] + string (6) "Shenzhen"    ["sex"] = > String (3) "Male"    ["info"] = + Array (2) {      ["age"] + int (+)      ["phone"] = + string (5) "12345"    }< c8/>}

If you want to check a field, you can use GetField ();

$result = $m->where ($map)->getfield (' info ');

Find out.

Array (2) {  ["age"] + int (+)  ["phone"] + = string (5) "12345"}

If you want to check the value of the age key, directly

$result = $m->where ($map)->getfield (' info.age ');

returns INT (20)

Query of Time section, to be queried in array form

For example, there is a key "time" in the document to find documents between 2015/815-2015/9/1.

$map =array (' Time ' =>array (' $gt ' =>int, ' $lt ' =>int))

$result = $m->where ($map)->select ()

where int represents the timestamp.

(3) Delete--delete ();

$result = $m->where ($map)->delete ();

The deletion of this delete is to delete the entire document.

(4) Modify--save ()

Set

For example, re-modify the sex=> ' male ' in the document and change to Sex=> ' "female"

$update [' Sex ']=array (' Set ', ' female '); $m->where ($map)->save ($update);

Results:

Array (5) {    ["_id"] + int (4)    ["name"] + = string (6) "John Doe"    ["addr"] + string (6) "Shenzhen"    ["sex"] = > String (3) "Female"    ["info"] = + Array (2) {      ["age"] + int (+)      ["phone"] = + string (5) "12345"    }

For example, modify the value of a key in an inline document, such as age

$update [' Info.age ']=array (' Set '), $m->where ($map)->save ($update);

Results:

Array (5) {    ["_id"] + int (3)    ["name"] + = string (6) "John Doe"    ["addr"] + string (6) "Shenzhen"    ["sex"] = > String (3) "Female"    ["info"] = + Array (2) {      ["age"] + int (+)      ["phone"] = + string (5) "12345"    }< c8/>}

unset

For example, to delete a key.

For example, delete the addr key in the document

$update [' addr ']=array (' unset ');  $m->where ($map)->save ($update);

Results:

Array (4) {    ["_id"] + int (3)    ["name"] + = string (6) "John Doe"    ["sex"] = + string (3) "Female"    ["info"] = > Array (2) {      ["age"] + int (+)      ["phone"] + = string (5) "12345"}  }

you can see there's no addr key.

push--append a value to the field (must be an array type) inside

such as an array (this does not include a relational array)

$data =array (          "Name" = "John Doe",          "addr" and "Shenzhen",          "sex" = "male",          "info" =>array (              "Age" = "              Phone" = "12345", "          num" =>array ();        );   $result = $m->add ($data);

Num is an array that modifies the added data inside.

$update [' num ']=array (' push ', 1); $m->where ($map)->save ($update);

Results:

Array (5) {    ["_id"] + int (3)    ["name"] + = string (6) "John Doe"    ["sex"] = + string (3) "Female"    ["info"] = > Array (2) {      ["age"] + int (+)      ["phone"] + = string (5) "12345"    }   ["num"] = = Array (1) { C27/>[0] = Int (1)    }  }

If you want to add an array

$update [' num ']=array (' push ', array (' subject ' = ' php '));      $m->where ($map)->save ($update);

Results:

Array (5) {    ["_id"] + int (3)    ["name"] + = string (6) "John Doe"    ["sex"] + = string (3) "Female"    ["info"] = Array (2) {      ["age"] + int (+)      ["phone"] + = string (5) "12345"    }    ["num"] = + Array (2) {      [ 0] = = Int (1)      [1] = = Array (1) {        ["subject"] = + string (3) "PHP"}}  }

pull--A value in the Delete field (must be an array field) by value

Now you want to delete the array (' suject ' + ' php ') that you just added in the NUM array

$update [' num ']=array (' pull ', array (' subject ' = ' php ')); $m->where ($map)->save ($update);

Results:

Array (5) {    ["_id"] + int (3)    ["name"] + = string (6) "John Doe"    ["sex"] + = string (3) "Female"    ["info"] = Array (2) {      ["age"] + int (+)      ["phone"] + = string (5) "12345"    }    ["num"] = + Array (1) {      [0] =& Gt Int (1)    }  }

You can see that the NUM array has no Array (' suject ' = ' php ');

(5) Statistical--count ()

$result = $m->where ($map)->count ();

At this point, the above methods are tested in practice, MONGO most commonly used, can meet the business requirements of the method summary end. If there is anything wrong, please point out!
