                    mirror(string $originDir, string $targetDir[, Traversable|null $iterator = null ][, array<string|int, mixed> $options = [] ]) : void

Copies files and directories from the origin directory into the target directory. By default:

existing files in the target directory will be overwritten, except if they are newer (see the override option)
files in the target directory that do not exist in the source directory will not be deleted (see the delete option)

Parameters

$originDir : string

$targetDir : string

$iterator : Traversable|null = null

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)
