Cook Data Utils
===============

[](#cook-data-utils)

Cook Data Utils is a PHP library providing utility functions for handling collections, arrays, strings, numbers, and dates.
The module is designed with performance, modularity, and lazy evaluation in mind.

Features
--------

[](#features)

- Collection Handling (map, filter, reduce, lazy evaluation)
- Array Manipulations (grouping, transformation)
- String Formatting (camelCase, snake\_case conversion)
- Number Formatting (rounding, precision formatting)
- Date Utilities (formatting, differences)

Installation
------------

[](#installation)

Install the package using Composer:

```
composer require cook/data-utils
```

Usage examples
--------------

[](#usage-examples)

### Collection

[](#collection)

```
use Cook\DataUtils\Collection;

$collection = new Collection([1, 2, 3, 4, 5]);

// Map: Multiply each number by 2
$doubled = $collection->map(fn(int $n) => $n * 2);
print_r(iterator_to_array($doubled)); // [2, 4, 6, 8, 10]

// Filter: Keep only even numbers
$filtered = $collection->filter(fn(int $n) => $n % 2 === 0);
print_r(iterator_to_array($filtered)); // [2, 4]

// Reduce: Sum all numbers
$sum = $collection->reduce(fn(int $acc, int $n) => $acc + $n, 0);
echo "Sum: $sum\n"; // Sum: 15
```

### Array Utilities

[](#array-utilities)

```
use Cook\DataUtils\ArrayHelper;

$data = [
    ['id' => 1, 'category' => 'A'],
    ['id' => 2, 'category' => 'B'],
    ['id' => 3, 'category' => 'A'],
];

// Group by category
$grouped = ArrayHelper::groupBy($data, 'category');
print_r($grouped);
```

### String Formatting

[](#string-formatting)

```
use Cook\DataUtils\StringFormatter;

echo StringFormatter::toCamelCase('hello_world'); // helloWorld
echo StringFormatter::toSnakeCase('HelloWorld');  // hello_world
```

### Number Formatting

[](#number-formatting)

```
use Cook\DataUtils\NumberFormatter;

echo NumberFormatter::format(123.456, 2); // 123.46
echo NumberFormatter::roundUp(123.456, 0); // 124
echo NumberFormatter::roundDown(123.999, 0); // 123
```

### Date Utilities

[](#date-utilities)

```
use Cook\DataUtils\DateHelper;

echo DateHelper::now(); // 2024-03-01 12:34:56
echo DateHelper::format('2024-03-01 12:34:56', 'Y-m-d'); // 2024-03-01
echo DateHelper::diffInDays('2024-03-01', '2024-03-06'); // 5
```

Development & Testing
-------------------------

[](#development--testing)

Run tests using PHPUnit:

```
vendor/bin/phpunit
```

Check code style using PHP CodeSniffer:

```
vendor/bin/phpcs --standard=PSR12 src/
```
