Transformer is a PHP package for sanitizing and formatting data powered by Laravel's validation components.

Transformer is a PHP package for sanitizing and formatting data powered by Laravel's validation components. The package uses a familiar Laravel validation-like syntax to transform data using callable functions, classes, and more:

use Closure;
 
// example available functions at runtime:
function to_carbon($value)
{
    return new Carbon\Carbon($value);
}
 
function only_numbers($value)
{
    return preg_replace("/[^0-9]/",'',$value);
}
 
$input = [
  'first_name' => '    jim    ',
  'last_name' => '   thompson',
  'phone_number' => '123-456-7890',
  'date_of_birth' => "1991-05-01",
];
 
(new DataTransformer($input, [
    'first_name' => 'trim|ucfirst',
    'last_name' => 'trim|ucfirst',
    'phone_number' => 'only_numbers',
    'date_of_birth' => 'to_carbon|->format:m/d/y',
]))->transform();
 
// Returns:
// [
//     "first_name" => "Jim",
//     "last_name" => "Thompson",
//     "phone_number" => "1234567890",
//     "date_of_birth" => "05/01/91",
// ]

Those familiar with Laravel's validation API will notice the string-based transformer rules. Also, as seen in the snippet, this package has a "chainable" syntax (to_carbon|->format:m/d/y) that can chain additional calls on a piece of data.

You can also transform data using closures or a class implementing the provided Transformable interface. Additionally, this package supports nested array data using dot notation, wildcard inputs (apply functions on keys matching a wildcard pattern), and more.

You can learn more about this package, get full installation instructions, and view the source code on GitHub.
