class Finder implements IteratorAggregate, Countable

Finder allows to build rules to find files and directories.

It is a thin wrapper around several specialized iterator classes.

All rules may be invoked several times.

All methods return the current Finder object to allow easy chaining:

$finder = Finder::create()->files()->name('*.php')->in(DIR);

Constants

IGNORE_VCS_FILES

IGNORE_DOT_FILES
