Sanitize and Format Data in PHP with the Transformer Package

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:

 1use Closure;
 2 
 3// example available functions at runtime:
 4function to_carbon($value)
 5{
 6    return new Carbon\Carbon($value);
 7}
 8 
 9function only_numbers($value)
10{
11    return preg_replace("/[^0-9]/",'',$value);
12}
13 
14$input = [
15  'first_name' => '    jim    ',
16  'last_name' => '   thompson',
17  'phone_number' => '123-456-7890',
18  'date_of_birth' => "1991-05-01",
19];
20 
21(new DataTransformer($input, [
22    'first_name' => 'trim|ucfirst',
23    'last_name' => 'trim|ucfirst',
24    'phone_number' => 'only_numbers',
25    'date_of_birth' => 'to_carbon|->format:m/d/y',
26]))->transform();
27 
28// Returns:
29// [
30//     "first_name" => "Jim",
31//     "last_name" => "Thompson",
32//     "phone_number" => "1234567890",
33//     "date_of_birth" => "05/01/91",
34// ]

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.
