From: timminn at gmail dot com Operating system: Arch Linux 2.6.31 PHP version: 5.3.1 PHP Bug Type: Arrays related Bug description: Last Array Element Replaced by Second Last one Description: ------------ if AN ARRAY WITHIN AN OBJECT is used in "a straight manner" in the foreach() loop, with the references to its values[poor English, see the SECOND foreach() in the submitted code to understand I mean], the last value in the array will be REPACED with the second last one ACCIDENTALLY, WITHOUT ANY ASSIGNMENT OPERATION. Reproduce code: --------------- <?php class myc{ public $a; } $o3->a = Array( 11, 22 ); //loop ONE foreach( $o3->a as $k => $v ) echo $v. ' '; //EXPECT 11 22 , CORRECT OUTPUT echo "\n=========\n"; //loop TWO notice the reference & sign for $v foreach( $o3->a as $k => & $v ) echo $v. ' '; //EXPECT 11 22 , CORRECT OUTPUT echo "\n=========\n"; //loop THREE foreach( $o3->a as $k => $v ) echo $v. ' '; //EXPECT 11 22 , BUT WRONG OUTPUT: 11 11 echo "\n=========\n"; ?> Expected result: ---------------- 11 22 11 22 11 22 Actual result: -------------- 11 22 11 22 11 11 -- Edit bug report at http://bugs.php.net/?id=51049&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51049&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51049&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=51049&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=51049&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51049&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51049&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51049&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51049&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51049&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51049&r=support Expected behavior: http://bugs.php.net/fix.php?id=51049&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51049&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51049&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51049&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51049&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51049&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51049&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51049&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51049&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51049&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51049&r=mysqlcfg
