HashΒΆ
Zend\Validator\File\Hash allows you to validate if a given file’s hashed contents matches the supplied hash(es) and algorithm(s).
Note
This validator requires the Hash extension from PHP. A list of supported hash algorithms can be found with the hash_algos() function.
Supported Options
The following set of options are supported:
- hash (string)
Hash to test the file against.
- algorithm (string) default: "crc32"
Algorithm to use for the hashing validation.
Usage Examples
1 2 3 4 5 6 7 8 9 10 | // Does file have the given hash?
$validator = new \Zend\Validator\File\Hash('3b3652f', 'crc32');
// Or, check file against multiple hashes
$validator = new \Zend\Validator\File\Hash(array('3b3652f', 'e612b69'), 'crc32');
// Perform validation with file path
if ($validator->isValid('./myfile.txt')) {
// file is valid
}
