Description:
------------
When this is run from the command line: "php mytest.php" on the local 
machine, it connects successfully to the remote database.  When it's 
run as a webpage, it dies with the mysql_error message of "Unknown 
MySQL server host 'mysql.vobj.org' (2)"

Command line access "mysql -h mysql.vobj.org ..." works fine.

If I substitute the IP address for the hostname, the webpage connects.

NOTE: vobj.org is hosted by dreamhost, and while mysql.vobj.org maps 
to 
67.205.28.132, 67.205.28.132 maps to thadison.masevo.dreamhost.com.
Maybe there's some IP security check that causes failure without 
generating a useful error message.

Fedora 11 host, Apache/2.2.13 (Fedora)

Reproduce code:
---------------
<?php

# $host='67.205.28.132';
$host='mysql.vobj.org';
$database='bugdemo';
$dbuser='bugdemo';
$pw='PHPisGreat';

$link = mysql_connect($host,$dbuser,$pw)
    or die('Could not connect: ' . mysql_error() );
mysql_select_db($database) or die('Could not select database '.$database);

echo "successful connection<br />\n";
mysql_close($link);
?>

Expected result:
----------------
Code should say "successful connection<br />\n"

Actual result:
--------------
Could not connect: MySQL server host 'mysql.vobj.org' (2)
