Installation

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 utility functions for working with the local filesystem, environment variables, system resources, and more.

use Vairogs\Functions\Local\Functions;

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

// Check if a file exists in the current working directory
$exists = $local->fileExistsCwd('filename.txt');

// Create a directory
$created = $local->mkdir('/path/to/directory');

// Get an environment variable
$value = $local->getenv('VARIABLE_NAME');

// Format a file size in a human-readable way
$size = $local->humanFileSize(1024 * 1024); // "1.00M"

// Check if PHP extensions or Composer packages are installed
$installed = $local->isInstalled(['package1', 'package2']);

// Check if a class from a package will be available at runtime
$available = $local->willBeAvailable('package-name', 'Namespace\\ClassName', ['parent-package']);

// Get the cURL user agent string
$userAgent = $local->getCurlUserAgent();

Using Traits Directly

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

use Vairogs\Functions\Local\Traits\_FileExistsCwd;
use Vairogs\Functions\Local\Traits\_MkDir;
use Vairogs\Functions\Local\Traits\_GetEnv;

class MyClass
{
    // Import the traits you need
    use _FileExistsCwd;
    use _MkDir;
    use _GetEnv;

    public function doSomething(): void
    {
        // Use the methods directly
        $exists = $this->fileExistsCwd('filename.txt');
        $created = $this->mkdir('/path/to/directory');
        $value = $this->getenv('VARIABLE_NAME');
    }
}
