LessThanOrEqual

Validates that a value is less than or equal to another value. Can compare between strings, numbers and dates.

LessThanOrEqual(
    mixed $constraint,
    ?string $message = null
);

Basic Usage

Validator::lessThanOrEqual(20)->validate(10); // true
Validator::lessThanOrEqual(10)->validate(10); // true

Validator::lessThanOrEqual(2.5)->validate(1.5); // true
Validator::lessThanOrEqual(1.5)->validate(1.5); // true

Validator::lessThanOrEqual('beta')->validate('alpha'); // true
Validator::lessThanOrEqual('alpha')->validate('alpha'); // true

Validator::lessThanOrEqual(new DateTime('today'))->validate(new DateTime('yesterday')); // true
Validator::lessThanOrEqual(new DateTime('today'))->validate(new DateTime('today')); // true

Note

String comparison is case-sensitive, meaning that comparing "hello" with "Hello" is different. Check strcmp for more information.

Note

An UnexpectedValueException will be thrown when trying to compare incomparable values, like a string with an int.
