$config->find('no', 'yes', 'bool');     // Smart converting popular word to boolean value
$config->get('key', 42, 'strip, trim'); // Chain of filters

// Your custom handler
$config->get('key', 42, function($value) {
    return (float)str_replace(',', '.', $value);
});
```

### Serialize to PHP Array

Source: https://github.com/jbzoo/data/blob/master/README.md

Shows how to represent the data structure as a PHP array. This is a fundamental data type in PHP for storing collections of data.

```php
<?php

return array(
    'empty' => '',
    'zero' => '0',
    'string' => ' ',
    'tag' => '<a href="http://google.com">Google.com</a>',
    'array1' => array(
        0 => '1',
        1 => '2',
    ),
    'section' => array(
        'array2' => array(
            0 => '1',
            12 => '2',
            3 => '3',
        ),
    ),
    'section.nested' => array(
        'array3' => array(
            '00' => '0',
            '01' => '1',
        ),
    ),
);
```

### Remove Data from JBZoo Data Object

Source: https://github.com/jbzoo/data/blob/master/README.md

Demonstrates how to remove keys and their associated values from a JBZoo Data object. Supports both a dedicated `remove()` method and standard PHP `unset()` syntax.

```php
// Unset
$config->remove('key');
unset($config['key']);
unset($config->key);
```

### PHP Benchmark: GetValueInner

Source: https://github.com/jbzoo/data/blob/master/README.md

Benchmarks the performance of retrieving a deeply nested value within various data structures. Compares native PHP arrays, ArrayObject, and custom Data objects. Nested access in Data objects is significantly slower than in native arrays or ArrayObjects.

```php
<?php

namespace Jbzoo\Data\Test\Benchmark;

use Jbzoo\Data\Data;
use Jbzoo\Data\Tests\Helper\CreateArrayHelper;
use PhpBench\Benchmark\Metadata\Metadata;

class GetValueInnerBench
{
    /**
     * @var int
     */
    private $size = 1000000;

    /**
     * @var array
     */
    private $array;

    public function setUp(): void
    {
        $this->array = CreateArrayHelper::generateHugeArray($this->size);
    }

    /**
     * @return array
     */
    public function provideSubject(): array
    {
        return [
            'Native' => [$this->array],
            'ArrayObject' => [new \ArrayObject($this->array)],
            'Data' => [new Data($this->array)],
        ];
    }

    /**
     * @Subject("GetValueInner")
     * @Iterations(5)
     * @AssertGroups({"Native", "ArrayObject", "Data"})
     */
    public function benchGetValueInner(array $object): void
    {
        // Accessing a nested key.
        $value = $object['first_key']['second_key']['third_key'];
    }
}

```

### PHP Strict Types Declaration

Source: https://github.com/jbzoo/data/blob/master/CLAUDE.md

Enforces strict type checking in PHP files. This declaration must be the very first statement in a PHP file, before any other code.

```php
declare(strict_types=1);
```
