Discovered today: fopen() opens '.' and '..' but fread() returns nothing
without errors nor end-of-file, so this loop:
$f = fopen('.', 'r');
if( $f === FALSE ) die("fopen failed");
$n = 0;
while(($s = fread($f, 10)) !== FALSE)
$n += strlen($s);
fclose($f);
echo "total bytes read: $n\n";
never ends! The same happens with '..'. Tested on PHP 5.6.3 and 7.0.0
under Slackware 14.1 32-bits. Under Vista, instead, fopen() fails as
expected.
Bug or specific feature under Linux?
