File Validators

Md5

Laminas\Validator\File\Md5 allows you to validate if a given file's hashed contents matches the supplied md5 hash(es). It is subclassed from the Hash validator to provide a validator that supports only the MD5 algorithm.

Supported Options

The following set of options are supported:

• hash: String hash or array of hashes against which to validate.

Basic Usage

use Laminas\Validator\File\Md5;

// Does file have the given hash?
$validator = new Md5('3b3652f336522365223');

// Or, check file against multiple hashes
$validator = new Md5([
    '3b3652f336522365223', 'eb3365f3365ddc65365'
]);

// Or use options notation:
$validator = new Md5(['hash' => [
    '3b3652f336522365223', 'eb3365f3365ddc65365'
]]);


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