Writes the contents of `string` to the file

### Parameter-Liste

`str`

  The string to be written to the file.

`length`

  If the `length` argument is given, writing will stop after `length` bytes have been written or the end of `string` is reached, whichever comes first.

### Beispiele

Beispiel #1 SplFileObject::fwrite example

`<?php
$file = new SplFileObject("fwrite.txt", "w");
