File rewrite not working?

test.php

<?php
$filec = fopen('test.txt','w');

$arr = file('test.txt');

foreach ($arr as $key => $value) {
    fwrite($filec,$value);
}

fclose($filec);
?>

test.txt

When I run test.php, test.txt is emptied. Does anyone know why?

Echoing $value, etc seems to work.

From stackoverflow

• When you call fopen with w, you are effectively clearing the file. When you call file, you're reading from that cleared file.

  Put the file call before the fopen one.
