Caution: The documentation you are viewing is
for an older version of Zend Framework.
You can find the documentation of the current version at:
Between Validator — Zend Framework 2 2.3.9 documentation
Zend\Validator\Between allows you to validate if a given value is between two other values.
Zend\Validator\Between supports only number validation
It should be noted that Zend\Validator\Between supports only the validation of numbers. Strings or dates can not be validated with this validator.
The following options are supported for Zend\Validator\Between:
Per default this validator checks if a value is between min and max where both border values are allowed as value.
1 2 3 4
$valid = new Zend\Validator\Between(array('min' => 0, 'max' => 10)); $value = 10; $result = $valid->isValid($value); // returns true
In the above example the result is TRUE due to the reason that per default the search is inclusively the border values. This means in our case that any value from ‘0’ to ‘10’ is allowed. And values like ‘-1’ and ‘11’ will return FALSE.
Sometimes it is useful to validate a value by excluding the border values. See the following example:
1 2 3 4 5 6 7 8 9 10
$valid = new Zend\Validator\Between( array( 'min' => 0, 'max' => 10, 'inclusive' => false ) ); $value = 10; $result = $valid->isValid($value); // returns false
The example is almost equal to our first example but we excluded the border value. Now the values ‘0’ and ‘10’ are no longer allowed and will return FALSE.
