Timezone Validator — Zend Framework 2 2.4.9 documentation

Zend\Validator

Timezone Validator

Zend\Validator\Timezone allows validating if an input string represents a timezone.

Supported validation types

The Zend\Validator\Timezone validator is capable of validating the abbreviation (e.g. “ewt”) as well as the location string (e.g. “America/Los_Angeles”). These options are stored in the validator as LOCATION, ABBREVIATION, and ALL class constants.

Basic Usage

The default validation type will check again abbreviations as well as the location string.

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

 $validator->isValid('America/Los_Angeles'); // returns true
 $validator->isValid('ewt'); // returns true
 $validator->isValid('Foobar');  // returns false

To validate against only the location string you can set the type:

 $validator = new Zend\Validator\Timezone();
 $validator->setType(Zend\Validator\Timezone::LOCATION);

 $validator->isValid('America/Los_Angeles'); // returns true
 $validator->isValid('ewt'); // returns false
 $validator->isValid('Foobar');  // returns false
