note 49649 added to function.eregi

The gethostbyname($regs[2]) == $regs[2] is a bad idea. Some domain names have a MX record but not an IP number. The first example I found is jhu.edu domain: sven@chef:~$ host jhu.edu jhu.edu A record currently not present sven@chef:~$ host -t mx jhu.edu jhu.edu MX 10 smtp.johnshopkins.edu ---- Manual Page -- http://www.php.net/manual/en/function.eregi.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+49649 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+49649&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+49649&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+49649&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+49649&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+49649&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+49649&report=yes Search -- http://master.php.net/manage/user-notes.php
