From: Operating system: linux PHP version: 5.3SVN-2011-09-20 (SVN) Package: MySQL related Bug Type: Bug Bug description:Warning thrown
Description: ------------ --- >From manual page: http://www.php.net/function.mysql-ping#refsect1-function.mysql-ping-description --- Mysql_ping is in my vision used to check wether your connection is still alive, by pinging the server since PHP 5.0.38 this function no longer autoreconnects, so its a real "Check if connection is alive" function. However if the connection is not alive it still throws a warning: mysql_ping(): 8 is not a valid MySQL-Link resource Which is obvious, because thats why you use this function... Test script: --------------- <?php error_reporting(E_ALL); $rConnection = mysql_connect("host", "user", "pass") or die("Could not connect"); sleep(60); if (false === mysql_ping($rConnection)) { echo "Connection gone"; } else { echo "Connection alive"; } Expected result: ---------------- Connection gone Actual result: -------------- mysql_ping(): 8 is not a valid MySQL-Link resource Connection gone -- Edit bug report at https://bugs.php.net/bug.php?id=55741&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55741&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55741&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55741&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55741&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55741&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55741&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55741&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55741&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55741&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55741&r=support Expected behavior: https://bugs.php.net/fix.php?id=55741&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55741&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55741&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55741&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55741&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55741&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55741&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55741&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55741&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55741&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55741&r=mysqlcfg
