## Validating digits

To validate if a given value contains only digits and no other characters, simply call the validator like shown in this example:

    $validator = new Zend_Validate_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_Validate_Int` or `Zend_Validate_Float`.
