Bug #71988 [NEW]: an element of $GLOBALS gets inexplicably rewritten

From: liv999 at hotmail dot com Operating system: Linux/CentOS, Ubuntu PHP version: Irrelevant Package: *General Issues Bug Type: Bug Bug description:an element of $GLOBALS gets inexplicably rewritten Description: ------------ I encountered a strange behavior of $GLOBALS array. After defining an element of it, then using another element of it in some initializations and calculations, the iniital element gets affected with values from the operations performed, although it was not involved. If I change the GLOBALS name to something else (like GLOBALS2) the result is correct, thus it has to do with the GLOBALS properties. Test script: --------------- <?php //initialization of an element of GLOBALS $GLOBALS['categories'] = array(1=>'z',2=>'x',3=>'c',4=>'v',5=>'r'); print_r($GLOBALS['categories']); //another element $GLOBALS['videos'] = array(1=>'a',2=>'b',3=>'c',4=>'d'); //some operations $videosCategories = array(1=>array(2,3,4,5),2=>array(12,13,14,15),3=>array(22,23,24,25),4=>array(32,33,34,35)); foreach($videosCategories as $videoId =>$categories) $GLOBALS['videos'][$videoId]['category'] = implode(',',$categories); //the initial element is reqritten print_r($GLOBALS['categories']); Expected result: ---------------- The 2 arrays should be the same, as it is the same GLOBALS element. -- Edit bug report at https://bugs.php.net/bug.php?id=71988&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71988&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71988&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71988&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71988&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71988&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71988&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71988&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71988&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71988&r=support Expected behavior: https://bugs.php.net/fix.php?id=71988&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71988&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71988&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71988&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71988&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71988&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71988&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71988&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71988&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71988&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71988&r=mysqlcfg
