File Validators

Exists

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

This validator is inversely related to the NotExists validator.

Supported Options

The following set of options are supported:

• directory: Array of directories, or comma-delimited string of directories.

Usage Examples

use Laminas\Validator\File\Exists;

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

// ...or with array notation
$validator = new Exists(['/tmp', '/var/tmp']);

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

Checks against all directories

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