PDOx

PDOx is a small PDO extension that enables developers to simple run a single query to map a table to the desired object. For this purpose it utilizes either native PDO or laminas-hydrator.

Installation

Simply run composer require jinya/pdox in your project.

Usage

PDOx contains three methods apart from the default PDO methods.

$pdo->fetchObject($query, $prototype, $parameters, $strategies)

This method allows you to fetch one single object from the query and hydrate the result into a class of the type of $prototype. An example call can look like this:

<?php
use Laminas\Hydrator\Strategy\BooleanStrategy;

require_once __DIR__ . '/vendor/autoload.php';

$pdox = new Jinya\PDOx\PDOx('sqlite::memory:');
$result = $pdox->fetchObject('SELECT * FROM table_test WHERE id = ?', new MyObject(), [1], [
    'active' => new BooleanStrategy('1','0'),
]);
var_dump($result);

The code above is really simple, as first parameter you give it the query, as second parameter a new instance of the object the PDOx should hydrate into, as third the parameters of your query and lastly the strategies. Strategies are a component of laminas hydrator and you can find our more about them here.

$pdo->fetchIterator($query, $prototype, $parameters, $strategies)

This method allows you to fetch an iterator of objects from the query and hydrate the results into a class of the type of $prototype. An example call can look like this:

<?php
use Laminas\Hydrator\Strategy\BooleanStrategy;

require_once __DIR__ . '/vendor/autoload.php';

$pdox = new Jinya\PDOx\PDOx('sqlite::memory:');
$result = $pdox->fetchIterator('SELECT * FROM table_test WHERE id = ?', new MyObject(), [1], [
    'active' => new BooleanStrategy('1','0'),
]);
var_dump($result);

The method call for fetchIterator and fetchObject is basically the same. You only need to replace the method name and PDOx does the rest for you.

$pdo->fetchArray($query, $prototype, $parameters, $strategies)

This method allows you to fetch an iterator of objects from the query and hydrate the results into a class of the type of $prototype. An example call can look like this:

<?php
use Laminas\Hydrator\Strategy\BooleanStrategy;

require_once __DIR__ . '/vendor/autoload.php';

$pdox = new Jinya\PDOx\PDOx('sqlite::memory:');
$result = $pdox->fetchArray('SELECT * FROM table_test WHERE id = ?', new MyObject(), [1], [
    'active' => new BooleanStrategy('1','0'),
]);
var_dump($result);

The method call for fetchArray and fetchIterator is basically the same. You only need to replace the method name and PDOx does the rest for you.

Configuration

PDOx introduces two new fields for the PDO options. These are passed in the constructor. Using these new options you can control whether PDOx should transform the field names and how it should handle empty results by returning null or throwing an exception.

PDOx::PDOX_NAMING_UNDERSCORE_TO_CAMELCASE

Possible Value: true or false

Purpose: Controls whether the casing should be converted between underscore case in the database to CamelCase in PHP

PDOx::PDOX_NO_RESULT_BEHAVIOR

Possible value: PDOx::PDOX_NO_RESULT_BEHAVIOR_NULL or PDOx::PDOX_NO_RESULT_BEHAVIOR_EXCEPTION

Purpose: Controls how PDOx should handle no result in fetchObject
