A basic validator and filter for time input.
Install with composer require illchuk/time-normalize.
You may install in your ZendFramework app by adding to your modules.config.php the following:
return [..., 'TimeNormalize' ,...]; // validator and filter both called 'Time'
Or use in a direct fashion:
use TimeNormalize\Validator\Time as TimeValidator;
use TimeNormalize\Filter\Time as TimeFilter;
$validator = new TimeValidator;
echo $validator->isValid('12:34am'); // true
echo $validator->isValid('12:34jm'); // false
$filter = new TimeFilter;
echo $filter->filter('12:34 am'); // '00:34'
echo $filter->filter('12:34 pm'); // '12:34'
echo $filter->filter('junk'); // 'junk'
