note 56924 added to function.gethostbynamel

In PHP 5.0.4, gethostbynamel returns an empty string instead of false if the lookup fails. A simple workaround for this error is to use is_array() in an IF block: <? $hosts = gethostbynamel($hostname); if (is_array($hosts)) { echo "Host ".$hostname." resolves to:<br><br>"; foreach ($hosts as $ip) { echo "IP: ".$ip."<br>"; } } else { echo "Host ".$hostname." is not tied to any IP."; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.gethostbynamel.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+56924 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+56924&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+56924&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+56924&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+56924&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+56924&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+56924&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+56924&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+56924&report=yes Search -- http://master.php.net/manage/user-notes.php
