Refactor Size rule
Currently, the Size rule does multiple things, yet it's limited. Because
it does many things, it's also confusing. Turning the Size rule into a
transformation allows for way more flexibility and clarity.

The syntax becomes more verbose, but the rule becomes more reusable.

Size

  • Size(string $unit, Rule $rule)

Validates whether the input is a file that is of a certain size or not.

v::size('KB', v::greaterThan(1))->isValid($filename);
v::size('MB', v::between(1, 2))->isValid($filename);
v::size('GB', v::lessThan(1))->isValid($filename);

Accepted data storage units are B, KB, MB, GB, TB, PB, EB, ZB, and YB.

This validator will accept:

  • string file paths
  • SplFileInfo objects (see SplFileInfo)
  • Psr\Http\Message\UploadedFileInterface objects (see PSR-7)
  • Psr\Http\Message\StreamInterface objects (see PSR-7)
