rename — Renames a file or directory

### Description

rename(string `$from`, string `$to`, ?resource `$context` = `null`): bool

Attempts to rename `from` to `to`, moving it between directories if necessary. If renaming a file and `to` exists, it will be overwritten. If renaming a directory and `to` exists, this function will emit a warning.

### Parameters

`from`

  The old name.

  > Note:

  > The wrapper used in `from` must match the wrapper used in `to`.

`to`

  The new name.

  > Note: On Windows, if `to` already exists, it must be writable. Otherwise rename() fails and issues `E_WARNING`.

`context`

  A context stream resource.

### Return Values

Returns `true` on success or `false` on failure.
