Iterator that filters which files and directories to copy, if null a recursive iterator is created
- $options : array<string|int, mixed> = []
-
An array of boolean options Valid options are:
- $options['override'] If true, target files newer than origin files are overwritten (see copy(), defaults to false)
- $options['copy_on_windows'] Whether to copy files instead of links on Windows (see symlink(), defaults to false)
