It could be used to check scalar values, objects or arrays from different sources (JSON, XML, Post Data)., _(*4)

Matching rules

Matching rules are strings that start with ':' (_colon_). You can use multiple matchers joined with space. Matcher could be any callable (name of function or closure). You can add your own rules or replace standard ones., _(*5)

- empty
- nonempty
- required
- in(a, b, ...)
- mixed
- any
Types, _(*7)
- array
- bool
- boolean
- callable
- double
- float
- int
- integer
- long
- numeric
- number
- object
- real
- resource
- scalar
- string
Numbers, _(*8)
- gt(n)
- gte(n)
- lt(n)
- lte(n)
- negative
- positive
- between(a, b)
Strings, _(*9)
- alnum
- alpha
- cntrl
- digit
- graph
- lower
- print
- punct
- space
- upper
- xdigit
- regexp(pattern)
- email
- url
- ip
- length(n)
- min(n)
- max(n)
- contains(needle)
- starts(s)
- ends(s)
- json
- date
Arrays, _(*10)
- count(n)
- keys(key1, key2, ...)
Objects, _(*11)
- instance(class)
- class_exists(className)
- property(name, value)
- method(name, value)

More details you can find here, _(*12)

Quantifiers for keys

! - one key required (default)
? - optional key
* - any count of keys
{3} - strict count of keys
{1,5} - range

For matchers (i.e. ':string') default quantifier is *, _(*13)
