#40654 [NEW]: reference causes foreach to fail proper iteration

From: saeven at saeven dot net Operating system: PHP version: 5.2.1 PHP Bug Type: Scripting Engine problem Bug description: reference causes foreach to fail proper iteration Description: ------------ Using a reference to build an array, later causes foreach to fail when reusing the reference variable name. The bug is solved by adding unset( $element); before block B, but this shouldn't be necessary. Reproduce code: --------------- // Block A - Build the Array $a = array( 2 => array( "value" => "a" ), 4 => array( "value" => "b" ), 6 => array( "value" => "c" ) ); $b = array( "orange", "blue", "green" ); foreach( $a as $id => &$element ){ $extra = array(); foreach( $b as $color ) array_push( $extra, $color ); $element += array( 'extra' => $extra ); } // Block B - Iterate through foreach( $a as $element ) echo $element["value"].' '; Expected result: ---------------- a b c Actual result: -------------- a b b -- Edit bug report at http://bugs.php.net/?id=40654&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=40654&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=40654&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=40654&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=40654&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=40654&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=40654&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=40654&r=needscript Try newer version: http://bugs.php.net/fix.php?id=40654&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=40654&r=support Expected behavior: http://bugs.php.net/fix.php?id=40654&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=40654&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=40654&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=40654&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=40654&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=40654&r=dst IIS Stability: http://bugs.php.net/fix.php?id=40654&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=40654&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=40654&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=40654&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=40654&r=mysqlcfg
