* The callback can return one of the following values:

|

* * false: the directory or file will NOT be copied (the "only" and "except" options will be ignored)

* - only: array, list of patterns that the file paths should match if they want to be copied.
|
|
* A path matches a pattern if it contains the pattern string at its end.
|
|
* For example, '.php' matches all file paths ending with '.php'.
|
|
* Note, the '/' characters in a pattern matches both '/' and '\' in the paths.
|
|
* If a file path matches a pattern in both "only" and "except", it will NOT be copied.
|
|
* - except: array, list of patterns that the files or directories should match if they want to be excluded from being copied.
|
|
* A path matches a pattern if it contains the pattern string at its end.
|
|
* Patterns ending with '/' apply to directory paths only, and patterns not ending with '/'
|
|
* apply to file paths only. For example, '/a/b' matches all file paths ending with '/a/b';
|
|
* and '.svn/' matches directory paths ending with '.svn'. Note, the '/' characters in a pattern matches
|
|
* both '/' and '\' in the paths.
|
|
* - caseSensitive: boolean, whether patterns specified at "only" or "except" should be case sensitive. Defaults to true.
|
|
* - recursive: boolean, whether the files under the subdirectories should also be copied. Defaults to true.
|
|
* - beforeCopy: callback, a PHP callback that is called before copying each sub-directory or file.
|
|
* If the callback returns false, the copy operation for the sub-directory or file will be cancelled.
|
|
* The signature of the callback should be: `function ($from, $to)`, where `$from` is the sub-directory or
|
|
* file to be copied from, while `$to` is the copy target.
|
|
* - afterCopy: callback, a PHP callback that is called after each sub-directory or file is successfully copied.
|
|
* The signature of the callback should be: `function ($from, $to)`, where `$from` is the sub-directory or
|
|
* file copied from, while `$to` is the copy target.
|
|
* - copyEmptyDirectories: boolean, whether to copy empty directories. Set this to false to avoid creating directories
|
|
* that do not contain files. This affects directories that do not contain files initially as well as directories that
|
|
* do not contain files at the target destination because files have been filtered via `only` or `except`.
|
|
* Defaults to true. This option is available since version 2.0.12. Before 2.0.12 empty directories are always copied.

|
|
* @param array $options options for file searching. Valid options are:
|
|
*
|
|
* - `filter`: callback, a PHP callback that is called for each directory or file.
|
|
* The signature of the callback should be: `function ($path)`, where `$path` refers the full path to be filtered.
|
|
* The callback can return one of the following values:
|
|
*
|
|
* * `true`: the directory or file will be returned (the `only` and `except` options will be ignored)
|
|
* * `false`: the directory or file will NOT be returned (the `only` and `except` options will be ignored)
|
|
* * `null`: the `only` and `except` options will determine whether the directory or file should be returned
|
|
*
|
|
* - `except`: array, list of patterns excluding from the results matching file or directory paths.
|
|
* Patterns ending with slash ('/') apply to directory paths only, and patterns not ending with '/'
|
|
* apply to file paths only. For example, '/a/b' matches all file paths ending with '/a/b';
|
|
* and `.svn/` matches directory paths ending with `.svn`.
|
|
* If the pattern does not contain a slash (`/`), it is treated as a shell glob pattern
|
|
* and checked for a match against the pathname relative to `$dir`.
|
|
* Otherwise, the pattern is treated as a shell glob suitable for consumption by `fnmatch(3)`
|
|
* with the `FNM_PATHNAME` flag: wildcards in the pattern will not match a `/` in the pathname.
|
|
* For example, `views/*.php` matches `views/index.php` but not `views/controller/index.php`.
|
|
* A leading slash matches the beginning of the pathname. For example, `/*.php` matches `index.php` but not `views/start/index.php`.
|
|
* An optional prefix `!` which negates the pattern; any matching file excluded by a previous pattern will become included again.
|
|
* If a negated pattern matches, this will override lower precedence patterns sources. Put a backslash (`\`) in front of the first `!`
|
|
* for patterns that begin with a literal `!`, for example, `\!important!.txt`.
|
|
* Note, the '/' characters in a pattern matches both '/' and '\' in the paths.
|
|
* You can find more details about the gitignore pattern format [here](https://git-scm.com/docs/gitignore/en#_pattern_format).
|
|
* - `only`: array, list of patterns that the file paths should match if they are to be returned. Directory paths
|
|
* are not checked against them. Same pattern matching rules as in the `except` option are used.
|
|
* If a file path matches a pattern in both `only` and `except`, it will NOT be returned.
|
|
* - `caseSensitive`: boolean, whether patterns specified at `only` or `except` should be case sensitive. Defaults to `true`.
|
|
* - `recursive`: boolean, whether the files under the subdirectories should also be looked for. Defaults to `true`.
|
|
* @return array files found under the directory, in no particular order. Ordering depends on the files system used.
|
|
* @throws InvalidArgumentException if the dir is invalid.

* When $owners is an index array the format is [0 => user, 1 => group], e.g. `[$myUser, $myGroup]`.
|
|
* It is also possible to pass an associative array, e.g. ['user' => $myUser, 'group' => $myGroup].
|
|
* In case $owners is an integer it will be used as user id.
|
|
* If `null`, an empty array or an empty string is passed, the ownership will not be changed.
|
|
* @param int|null $mode the permission to be set for the file or directory.
|
|
* If `null` is passed, the mode will not be changed.
