Validators

GreaterThan Validator

Zend\Validator\GreaterThan allows you to validate if a given value is greater than a minimum border value.

Only supports numbers

Zend\Validator\GreaterThan supports only the validation of numbers. Strings or dates can not be validated with this validator.

Supported options

The following options are supported for Zend\Validator\GreaterThan:

• inclusive: Defines if the validation is inclusive of the minimum value, or exclusive. It defaults to false.
• min: Sets the minimum allowed value.

Basic usage

To validate if a given value is greater than a defined minimum:

$valid  = new Zend\Validator\GreaterThan(['min' => 10]);
$value  = 8;
$return = $valid->isValid($value);
// returns false

The above example returns true for all values which are greater than 10.

Inclusive validation

Sometimes it is useful to validate a value by including the minimum value.

$valid  = new Zend\Validator\GreaterThan([
    'min' => 10,
    'inclusive' => true,
]);
$value  = 10;
$result = $valid->isValid($value);
// returns true

The example is identical to our first example, with the exception that we included the minimum value. Now the value '10' is allowed and will return true.
