note 56505 added to function.dns-get-record

I'm getting 'Fatal error: Call to undefined function: dns_get_record()' with PHP Version 4.4.0, though this feature must be built-in. Is there any solution? ---- Manual Page -- http://www.php.net/manual/en/function.dns-get-record.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+56505 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+56505&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+56505&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+56505&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+56505&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+56505&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+56505&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+56505&report=yes Search -- http://master.php.net/manage/user-notes.php
