zend.validator.file.exists.rst

Exists

Zend\Validator\File\Exists checks for the existence of files in specified directories.

This validator is inversely related to the NotExists validator <zend.validator.file.not-exists>.

Supported Options

The following set of options are supported:

• directory (string|array)

  Comma-delimited string (or array) of directories.

Usage Examples

// Only allow files that exist in ~both~ directories
$validator = new \Zend\Validator\File\Exists('/tmp,/var/tmp');

// ...or with array notation
$validator = new \Zend\Validator\File\Exists(array('/tmp', '/var/tmp'));

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

Note

This validator checks whether the specified file exists in all of the given directories. The validation will fail if the file does not exist in one (or more) of the given directories.
