Structural check of arrays for PHP 5.6+
This library can check a complex array structure against a given requirement. The purpose of this library is to create a better experience when testing a result set from an api or something similar.
composer require 1blankz7/php-structure-check
Create a requirement:
$requirement = new ListType( new ObjectType([ 'foo' => new StringType(), 'bar' => new IntType(), 'buzz' => new AnyType(), 'foobar' => new NullableType(new StringType()) ]) );
Have some sort of external data you want to check.
$data = [ [ 'foo' => 'foe', 'bar' => 'baz', 'buzz' => 'foe', 'foobar' => null ], [ 'foo' => 'foe', 'bar' => 7, 'buzz' => 'foe', 'foobar' => 'baz', ], [ 'foo' => , 'bar' => 9.1, 'foobar' => 'baz', ], ];
Check the data against the requirement.
$result = Checker::fulfills($data, $requirement);
The returned object holds information about the analysis. You can
check the result by calling
isValid() on the result object. To
fetch the errors, simply call
Currently the following types are supported:
There are some open issues with ideas for more types. Feel free to send pull requests.
Additionally you can implement the
TypeInterface and use your own type implementations.
Checks are special types which can be used to add more rules to a field. So you can check the length of a string, the count of elements in an array or determine if a numeric value is in a given range.
