However I had been experimenting with dns_get_record() before my original post and it produces strange results on my machine. And your example, on my machine, produces no output. <? $dns_result = dns_get_record("www.google.com", DNS_A, $authns, $addt); print_r($dns_result); print_r($authns); print_r($addt); /* result Array ( [0] => Array ( [host] => www.l.google.com [type] => A [ip] => 64.233.161.99 [class] => IN [ttl] => 136 ) [1] => Array ( [host] => www.l.google.com [type] => A [ip] => 64.233.161.147 [class] => IN [ttl] => 136 ) [2] => Array ( [host] => www.l.google.com [type] => A [ip] => 64.233.161.103 [class] => IN [ttl] => 136 ) [3] => Array ( [host] => www.l.google.com [type] => A [ip] => 64.233.161.104 [class] => IN [ttl] => 136 ) ) Array ( ) Array ( ) */ ?> Any suggestions?? Thanks, Brad
I have same results as you brad, I have Apache 2.2.3 + PHP 5.2.3RC1, so if you finally get it working, it's definitely not portable code :P Maybe it's an option to talk to a whois server? Tijnema -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
