Validators

Digits Validator

Zend\Validator\Digits validates if a given value contains only digits.

Installation requirements

Zend\Validator\Digits depends on the zend-filter component, so be sure to have it installed before getting started:

$ composer require zendframework/zend-filter

Supported options

There are no additional options for Zend\Validator\Digits:

Validating digits

To validate if a given value contains only digits and no other characters, call the validator as shown below:

$validator = new Zend\Validator\Digits();

$validator->isValid("1234567890"); // returns true
$validator->isValid(1234);         // returns true
$validator->isValid('1a234');      // returns false

Validating numbers

When you want to validate numbers or numeric values, be aware that this validator only validates digits. This means that any other sign like a thousand separator or a comma will not pass this validator. In this case you should use Zend\I18n\Validator\IsInt or Zend\I18n\Validator\IsFloat.
