Hi,

fstat() returns different results, in PIPE and REDIRECT.

I wrote Following script as both PIPE and REDIRECT

sample.php:
<?PHP
  $stat = fstat(STDIN);
  if ($stat['size'] > 0) {
    echo fread(STDIN, $stat['size']);
  else {
    echo "STDIN is empty.\n";
  }
}
?>

$ cat sample.php | php sample.php
In this case, The result was a disappointment.

$ php sample.php < sample.php
In this case, I obtained satisfactory results.

fstat() result is diffrent.
For PIPE,
  $stat['size'] = 0 // at any time
For REDIRECT
  $stat['size'] = `actual size'

Is this specifications ?

Pipes/FIFOs have neither a size nor can they been seeked.
This is expected behaviour; not a bug in PHP so marking it as bogus.
