Description:
------------
The documentation for dns_get_record says the return value is an array of associative arrays. It should also point out that if there is no DNS record for the domain being queried, it returns an empty string.

I can't reproduce that. Could you give a script that results in that behavior along with the version of PHP you're using?

daniel@daniel-laptop:~$ cat test.php
<?php
var_dump(dns_get_record('fooaskljdalskdj.com'));
?>
daniel@daniel-laptop:~$ php -nv; php -n test.php

array(0) {
}
daniel@daniel-laptop:~$ src/php-5.2.13/sapi/cli/php test.php
array(0) {
}

Hm. I misread my log, so I was too hasty in my original report. What I should have said is that on *error*, dns_get_record returns FALSE and triggers a warning:

Warning: dns_get_record() [function.dns-get-record]: res_nsend() failed in ...

I can't provide a test script that reliably makes dns_get_record() error out. I'm assuming it depends on network conditions and the like.

Ah, that makes more sense. It's been fixed now and should show up in the manual in a few days. Thanks for the report.
