README

A PHP library providing functions specific to Latvian language and data formats, including Latvian text comparison, sorting according to Latvian alphabet rules, and validation of Latvian personal identification codes.

Installation

Install the package via Composer:

composer require valksor/php-functions-latvian

Requirements

PHP 8.4 or higher

Usage

There are two ways to use this package: via the Functions class or by directly using the traits.

Using the Functions Class

The Functions class provides utilities for working with Latvian-specific data and text.

use Valksor\Functions\Latvian\Functions;

// Create a new Functions instance
$functions = new Functions();

// Validate a Latvian personal identification code
$isValid = $functions->validatePersonCode('32XXXXXXXXX'); // For new format
$isValid = $functions->validatePersonCode('XXXXXXXXXXX'); // For old format

// Sort an array of names according to Latvian alphabet rules
$names = [
    ['name' => 'Ēriks'],
    ['name' => 'Andris'],
    ['name' => 'Čalis'],
    ['name' => 'Zane'],
];
$functions->sortLatvian($names, 'name');
// Result: Andris, Čalis, Ēriks, Zane

// Compare two strings using Latvian alphabet rules
$result = $functions->compare(['name' => 'Ēriks'], ['name' => 'Andris'], 'name');
// Result: positive integer (Ēriks comes after Andris in Latvian alphabet)

Using Traits Directly

Alternatively, you can use the traits directly in your own classes:

use Valksor\Functions\Latvian\Traits\_Compare;
use Valksor\Functions\Latvian\Traits\_SortLatvian;
use Valksor\Functions\Latvian\Traits\_ValidatePersonCode;

class MyClass
{
    // Import the traits you need
    use _Compare;
    use _SortLatvian;
    use _ValidatePersonCode;

    public function doSomething(): void
    {
        // Validate a Latvian personal identification code
        $isValid = $this->validatePersonCode('32XXXXXXXXX');

        // Sort an array of names according to Latvian alphabet rules
        $names = [
            ['name' => 'Ēriks'],
            ['name' => 'Andris'],
            ['name' => 'Čalis'],
            ['name' => 'Zane'],
        ];
        $this->sortLatvian($names, 'name');

        // Compare two strings using Latvian alphabet rules
        $result = $this->compare(['name' => 'Ēriks'], ['name' => 'Andris'], 'name');
    }
}

Note that some traits may depend on other helper traits. For example, the _ValidatePersonCode trait uses _ValidatePersonCodeNew and _ValidatePersonCodeOld internally. The Functions class handles these dependencies for you, but if you use the traits directly, you may need to include these helper traits as well.
