A pragmatic and concise validation library written in PHP.

The idea behind [**Veritas**](http://en.wikipedia.org/wiki/Veritas) is implement a flexible easy to use validation engine so you can write validation code as easy as you can build questions in everyday language.

```
// Is $var a decimal value in the interval [-1,1]?
v::is($var)->dec()->in('[-1,1]')->verify();

// Is $var an array with a index 8 with value 'eight'?
v::is($var)->arr()->key(8,'eight')->verify();

// Is $var a string that represent a date in format year-month-day?
v::is($var)->str()->date('Y-m-d')->verify();

// Is $var an object with a property called 'name'?
v::is($var)->obj()->attr('name')->verify();

//Is $mail a valid email address from Gmail or Yahoo?
v:isEmail($mail)->contains('@gmail','@yahoo')->verify();
```
