From manual page:
http://www.php.net/function.getprotobyname#refsect1-function.getprotobyname-returnvalues

Return for unrecognized protocol is 0 instead of -1.

Test script:
---------------
<?php
$protocol = 'BLA';
$get_prot = getprotobyname($protocol);
if ($get_prot == -1) {
    echo 'Invalid Protocol';
} else {
    echo 'Protocol #' . $get_prot;
}
?>


Expected result:
----------------
Invalid Protocol

Actual result:
--------------
Protocol #0
