File Validators

WordCount

Laminas\Validator\File\WordCount validates that the number of words within a file match the specified criteria.

Supported Options

The following set of options are supported:

  • min: the minimum number of words required; null indicates no minimum.
  • max: the maximum number of words required; null indicates no maximum.

Basic Usage

use Laminas\Validator\File\WordCount;

// Limit the amount of words to a maximum of 2000:
$validator = new WordCount(['max' => 2000]);

// Limit the amount of words to between 100 and 5000:
$validator = new WordCount([
    'min' => 100,
    'max' => 5000,
]);

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

One of min or max is required. Omitting both options will cause an exception. Additionally, the min option must be numerically less than the max option.
