#51147 [NEW]: mysql_connect can't resolve hostname within apache module

From: kugel at rci dot rutgers dot edu Operating system: PHP version: 5.2.12 PHP Bug Type: Feature/Change Request Bug description: mysql_connect can't resolve hostname within apache module 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) -- Edit bug report at http://bugs.php.net/?id=51147&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51147&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51147&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=51147&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=51147&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51147&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51147&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51147&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51147&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51147&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51147&r=support Expected behavior: http://bugs.php.net/fix.php?id=51147&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51147&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51147&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51147&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51147&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51147&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51147&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51147&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51147&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51147&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51147&r=mysqlcfg
