Description:
------------
Note or warning here?

Reproduce code:
---------------
<?php
// truncate doesn't move the file pointer to the end of the file
$flog = fopen("text.txt", "w+");
fwrite($flog, "veeery veeery long string");
fseek($flog, -2, SEEK_END);
ftruncate($flog, 6);
fwrite($flog, "shortstr");
fclose($flog);
?>
Expected result:
