• min (integer|string) default: null

• max (integer|string) default: null

  The integer number of bytes, or a string in SI notation (ie. 1kB, 2MB, 0.2GB).

  The accepted SI notation units are: kB, MB, GB, TB, PB, and EB. All sizes are converted using 1024 as the base value (ie. 1kB == 1024 bytes, 1MB == 1024kB).

• useByteString (boolean) default: true

  Display error messages with size in user-friendly number or with the plain byte size.

Usage Examples

// Limit the file size to 40000 bytes
$validator = new \Zend\Validator\File\Size(40000);

// Limit the file size to between 10kB and 4MB
$validator = new \Zend\Validator\File\Size(array(
    'min' => '10kB', 'max' => '4MB'
));

// Perform validation with file path
if ($validator->isValid('./myfile.txt')) {
    // file is valid
}
