File

  • File()

Validates whether file input is as a regular filename.

v::file()->assert(__FILE__);
// Validation passes successfully

v::file()->assert(__DIR__);
// → "/path/to/dir" must be an accessible existing file

This validator will consider SplFileInfo instances, so you can do something like:

v::file()->assert(new SplFileInfo('/path/to/file.txt'));
// Validation passes successfully
