#33635 [NEW]: Get "couldn't fetch mysqli" error when attempting to write session data to data

From: tony at marston-home dot demon dot co dot uk Operating system: Windows XP PHP version: 5CVS-2005-07-10 (dev) PHP Bug Type: MySQLi related Bug description: Get "couldn't fetch mysqli" error when attempting to write session data to data Description: ------------ In my script I use a custom session handler to write all session data to the database. Through versions 5.0.0 to 5.0.4 this worked as expected, but with 5.0.5dev I am now getting an error. It only ever failos at the end of the script when writing out the session data. It always fails at the same place by generating a "Couldn't fetch mysqli" error. Reproduce code: --------------- function connect ($dbname) // establish a connection to the database { global $dbhost, $dbusername, $dbuserpass; static $dbconn; if (!$dbconn) { $dbconn = mysqli_connect($dbhost, $dbusername, $dbuserpass); if ($dbconn) { // use UTF8 for this connection $this->query = "SET names 'UTF8'"; $result = mysqli_query($dbconn, $this->query) or trigger_error($this, E_USER_ERROR); } // if } // if if (!$dbconn) { <== FAILS HERE ********************* return false; } elseif (!mysqli_select_db($dbconn, $dbname)) { return false; } else { $this->dbconnect = $dbconn; return true; } // if } // connect The full code is available from http://www.tonymarston.net/text.zip. The script to run is "test.php". Expected result: ---------------- At that point $dbconn is shown to be "object of mysqli", so it should not error. Actual result: -------------- At the line "if (!$dbconn)" the program jumps immediately to my error handler with the error "Couldn't fetch mysqli". -- Edit bug report at http://bugs.php.net/?id=33635&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33635&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33635&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33635&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33635&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33635&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33635&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33635&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33635&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33635&r=support Expected behavior: http://bugs.php.net/fix.php?id=33635&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33635&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33635&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33635&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33635&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33635&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33635&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33635&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33635&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33635&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33635&r=mysqlcfg
