#26805 [NEW]: fsockopen fails when hostname is given

From: mark dot salisbury at hp dot com Operating system: hpux PHP version: 4.3.4 PHP Bug Type: Sockets related Bug description: fsockopen fails when hostname is given Description: ------------ I was using fsockopen in a script, which worked fine until I upgraded from version 4.2.0 to 4.3.4. Oddly, I found a workaround for the bug by changing my code from: $fp = fsockopen($server_name, $port, $errno, $errstr); to: $fp = fsockopen(gethostbyname($server_name), $port, $errno, $errstr); Reproduce code: --------------- fsockopen($server_name, $port, $errno, $errstr); Expected result: ---------------- Warning: fsockopen(): php_network_getaddresses: getaddrinfo failed: host nor service provided, or not known in /local/apache1.3/htdocs/php_includes/http_post.php on line 45 Warning: fsockopen(): unable to connect to saturn:81 in /local/apache1.3/htdocs/php_includes/http_post.php on line 45 (errno=0 and errstr="error 0", I believe) The reason I believe this is a bug is that: a) Isn't fsockopen going to do something similiar to gethostbyname() if you pass a hostname and not an IP address to fsockopen? Why does it work when I pass it an IP address and not the host name? I would expect gethostbyname to fail also if my problem were external (DNS). b) everything worked fine until I upgraded PHP today. -- Edit bug report at http://bugs.php.net/?id=26805&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=26805&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=26805&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=26805&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=26805&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=26805&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=26805&r=needscript Try newer version: http://bugs.php.net/fix.php?id=26805&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=26805&r=support Expected behavior: http://bugs.php.net/fix.php?id=26805&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=26805&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=26805&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=26805&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=26805&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=26805&r=dst IIS Stability: http://bugs.php.net/fix.php?id=26805&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=26805&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=26805&r=float
