note 48493 added to function.gethostbyname

For doing basic RBL (Real Time Blacklist) lookups with this function do: <?php $host = '64.53.200.156'; $rbl = 'sbl-xbl.spamhaus.org'; // valid query format is: 156.200.53.64.sbl-xbl.spamhaus.org $rev = array_reverse(explode('.', $host)); $lookup = implode('.', $rev) . '.' . $rbl; if ($lookup != gethostbyname($lookup)) { echo "ip: $host is listed in $rbl\n"; } else { echo "ip: $host NOT listed in $rbl\n"; } ?> Tomas V.V.Cox ---- Manual Page -- http://www.php.net/manual/en/function.gethostbyname.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48493 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48493&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48493&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48493&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48493&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48493&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48493&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48493&report=yes Search -- http://master.php.net/manage/user-notes.php
