# Comparable values
|
|
|
|
For certain types you can't make comparisons out of the box in PHP but
|
|
Validation brings support to a few of them.
|
|
|
|
You can make comparison with the following data types:
|
|
|
|
- Countable: any object that implements `Countable` interface
|
|
- DateTimeInterface
|
|
- Numeric types
|
|
- Single character string
|
|
- Primitive types in general: normal operation comparison made by PHP
|
|
- Time string: [date and time format](http://php.net/datetime.formats)
|
|
that can be parsed by PHP
|
|
|
|
Below you can see some examples:
|
|
|
|
```php
|
|
v::min(100)->validate($collection); // true if it has at least 100 items
|
|
|
|
v::dateTime()
|
|
->between(new DateTime('yesterday'), new DateTime('tomorrow'))
|
|
->validate(new DateTime('now')); // true
|
|
|
|
v::numericVal()->max(10)->validate(5); // true
|
|
|
|
v::stringVal()->between('a', 'f')->validate('d'); // true
|
|
|
|
v::dateTime()->between('yesterday', 'tomorrow')->validate('now'); // true
|
|
``` |
