Umberto,
When I try this in OS X 10.10 php 5.5.14 (I've added newlines to output)
$ php -a
...
php > $f= fopen('.', 'r');
php > print_r( $f );
Resource id #2
php > $s = fread( $f, 10 );
php > print_r(strlen($s));
0
php > if ($s !== FALSE) print('NOT FALSE');
NOT FALSE
php > if ($s != FALSE) print('NOT FALSE');
php > if ($s == FALSE) print('IS FALSE');
IS FALSE
