# DBmodel # DBmodel
This library extends the builtin PDO object by several useful features. This library extends the builtin PDO object by several useful features.
## Basic usage
For testing create database `test` with user `test` and password `test`. In database create table `test` and insert same testing data.
```
CREATE TABLE `test` (
`id` int(11) PRIMARY KEY NOT NULL AUTO_INCREMENT,
`name` varchar(255) DEFAULT NULL,
`created` datetime DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci;
```
For basic testing run this code
```
<?php
require_once __DIR__.'/../src/DBmodel.php';
$db = new \TPsoft\DBmodel\DBmodel('mysql:host=127.0.0.1;dbname=test;charset=utf8mb4', 'test', 'test');
// test query
$result = $db->query("show tables");
print_r($result);
// test results
$result = $db->getAll("show databases");
print_r($result);
$result = $db->getAll("show tables");
print_r($result);
$result = $db->getCol("show tables");
print_r($result);
$result = $db->getTableColumns("test");
print_r($result);
$result = $db->getRow("select * from test where id = 10");
print_r($result);
?>
```
## Interactive create MODEL class
Create file `creatorModel.php` and paste bellow code
```
<?php
require_once __DIR__.'/../src/DBmodel.php';
require_once __DIR__.'/../src/creator.php';
$db = new \TPsoft\DBmodel\DBmodel('mysql:host=127.0.0.1;dbname=test;charset=utf8mb4', 'test', 'test');
$creator = new \TPsoft\DBmodel\Creator($db);
$creator->interact();
?>
```
now for each table run `php createModel.php` for interactive creating class for table.
```
$ php test2.php
New model name: Test
Table name: test
Entity name: test
Create MODEL class '/your/project/models/Test.php'? (y - yes, other - no) y
Create directory '/your/project/models'? (y - yes, other - no) y
Creating MODEL class ... MODEL class created
```
Creator build this MODEL class file
```

## Using MODEL class in your project
Illustrative example
```
<?php
require_once __DIR__.'/../src/DBmodel.php';
require_once __DIR__.'/../models/test.php';
$db = new \TPsoft\DBmodel\DBmodel('mysql:host=127.0.0.1;dbname=test;charset=utf8mb4', 'test', 'test');
// empty contructor of new MODEL class use last database handler
$test = new Test();
// exists ID 11
$result = $test->exist(11);
print_r($result);
// insert new record
$result = $test->test(null, array('name' => 'new record'));
print_r($result);
// update record ID 11
$result = $test->test(11, array('name' => 'updated record'));
print_r($result);
// get record ID 11
$result = $test->test(11);
print_r($result);
// delete record ID 11
$result = $test->test(11, null);
print_r($result);
// get all records
$result = $test->getList();
print_r($result);
// get combined list of ID and name
$result = $test->testCombo('id', 'name');
print_r($result);
?>
