Bug #64864 [NEW]: shuffle() and array_push are broken with PDO.

From: mail at kinesis dot me Operating system: Ubuntu Linux 13.04 x64 PHP version: 5.4.15 Package: PDO related Bug Type: Bug Bug description:shuffle() and array_push are broken with PDO. Description: ------------ $this->answer['id'] is always at the end, when it is supposed to be shuffled. This looks like a bug to me. array_rand() will not work either. $this->current_set=$this->dbh->query("SELECT DISTINCT id FROM $game_type WHERE id != '".(string)$this->answer['id']."' ORDER BY rand() LIMIT 2;")->fetchAll(PDO::FETCH_COLUMN); //$this->complete_set="" //echo "Current set separated by commas is ".implode(",",$this->current_set->fetchAll(PDO::FETCH_COLUMN)) + $this->answer['id']."<br />"; //$this->current_set=$this->current_set->fetchAll(PDO::FETCH_COLUMN); array_push($this->current_set,$this->answer['id']); explode(",",$this->current_set); shuffle($this->current_set); // $this->answer['id'] is always at the end? print_r($this->current_set); print_r($this->answer['id']); var_dump($this->current_set, 3); Test script: --------------- $this->current_set=$this->dbh->query("SELECT DISTINCT id FROM $game_type WHERE id != '".(string)$this->answer['id']."' ORDER BY rand() LIMIT 2;")->fetchAll(PDO::FETCH_COLUMN); //$this->complete_set="" //echo "Current set separated by commas is ".implode(",",$this->current_set->fetchAll(PDO::FETCH_COLUMN)) + $this->answer['id']."<br />"; //$this->current_set=$this->current_set->fetchAll(PDO::FETCH_COLUMN); array_push($this->current_set,$this->answer['id']); explode(",",$this->current_set); shuffle($this->current_set); // $this->answer['id'] is always at the end? print_r($this->current_set); print_r($this->answer['id']); var_dump($this->current_set, 3); Expected result: ---------------- I expect the array '$this->current_set' to have the value of $this->answer pushed towards the end. Then I shuffle() or array_rand() the array, but $this->answer always appears as the third element of the array no matter what I do. -- Edit bug report at https://bugs.php.net/bug.php?id=64864&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=64864&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=64864&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=64864&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=64864&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=64864&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=64864&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=64864&r=needscript Try newer version: https://bugs.php.net/fix.php?id=64864&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=64864&r=support Expected behavior: https://bugs.php.net/fix.php?id=64864&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=64864&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=64864&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=64864&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=64864&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=64864&r=dst IIS Stability: https://bugs.php.net/fix.php?id=64864&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=64864&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=64864&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=64864&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=64864&r=mysqlcfg
