# Length
|
|
|
|
- `Length(Validator $validator)`
|
|
|
|
Validates the length of the given input against a given validator.
|
|
|
|
```php
|
|
v::length(v::between(1, 5))->assert('abc');
|
|
// Validation passes successfully
|
|
|
|
v::length(v::greaterThan(5))->assert('abcdef');
|
|
// Validation passes successfully
|
|
|
|
v::length(v::lessThan(5))->assert('abc');
|
|
// Validation passes successfully
|
|
```
|
|
|
|
This validator can be used to validate the length of strings, arrays, and objects that implement the `Countable` interface.
|
|
|
|
```php
|
|
v::length(v::greaterThanOrEqual(3))->assert([1, 2, 3]);
|
|
// Validation passes successfully
|
|
|
|
v::length(v::equals(0))->assert(new SplPriorityQueue());
|
|
// Validation passes successfully
|
|
```
|
|
|
|
