Practical Use Cases

Let's look at a few practical examples of how Alfa Rex can be used:

Parsing ALFA files

$alfaFile = file_get_contents('path/to/your/alfafile.alf');
$parser = new Alfarex\Parser();
$document = $parser->parse($alfaFile);
// Further processing of the parsed document

Validating ALFA files

$alfaFile = file_get_contents('path/to/your/alfafile.alf');
$validator = new Alfarex\Validator();
if ($validator->validate($alfaFile)) {
    // The ALFA file is valid
} else {
    // There are errors in the ALFA file
}

Manipulating ALFA data

$alfaFile = file_get_contents('path/to/your/alfafile.alf');
$parser = new Alfarex\Parser();
$document = $parser->parse($alfaFile);

// Update a value in the document
$document['somefield'] = 'New Value';

// Save the manipulated document as a new ALFA file
file_put_contents('path/to/output.alf', Alfarex\Formatter::format($document));

Alfa Rex is an invaluable tool for developers working with ALFA data, providing advanced parsing, validation, and manipulation capabilities to streamline your workflow and improve the overall quality of your projects.
