matchmaker

PHP functions that help you validate structure of complex nested PHP arrays.

$books = [
    [
        'type' => 'book',
        'title' => 'Geography book',
        'chapters' => [
            'eu' => ['title' => 'Europe', 'interesting' => true],
            'as' => ['title' => 'America', 'interesting' => false]
        ]
    ],
    [
        'type' => 'book',
        'title' => 'Foreign languages book',
        'chapters' => [
            'de' => ['title' => 'Deutsch']
        ]
    ]
];

$pattern = [
    '*' => [
        'type' => 'book',
        'title' => ':string contains(book)',
        'chapters' => [
            ':string length(2) {1,3}' => [
                'title' => ':string',
                'interesting?' => ':bool',
            ]
        ]
    ]
];

matchmaker\matches($books, $pattern); // true

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

Matching rules

Matching rules are strings that start with ':'. 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.

  • General

  • empty

  • nonempty

  • required

  • in(a, b, ...)

  • mixed

  • any

  • Types

  • array

  • bool

  • boolean

  • callable

  • double

  • float

  • int

  • integer

  • long

  • numeric

  • number

  • object

  • real

  • resource

  • scalar

  • string

  • Numbers

  • gt(n)

  • gte(n)

  • lt(n)

  • lte(n)

  • negative

  • positive

  • between(a, b)

  • Strings

  • 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

  • count(n)

  • keys(key1, key2, ...)

  • Objects

  • instance(class)

  • property(name, value)

  • method(name, value)

More details you can find here

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 *
