From: oliver at teqneers dot de Operating system: Suse 9.0 PHP version: 4.3.8 PHP Bug Type: Arrays related Bug description: unset deletes array entries and its copied entries
Description: ------------ When I copy an array with a normal "=" the copy is not a real copy, but a reference to it. This only seems to happen to cascaded arrays. When an entry of the original array is unset, the copied entry will be unset as well. Reproduce code: --------------- $arr = array( 'in' => array(1,2,3) ); $copy = $arr; print_r($copy); unset( $arr['in'][1] ); print_r($copy); Expected result: ---------------- Array ( [in] => Array ( [0] => 1 [1] => 2 [2] => 3 ) ) Array ( [in] => Array ( [0] => 1 [1] => 2 [2] => 3 ) ) Actual result: -------------- Array ( [in] => Array ( [0] => 1 [1] => 2 [2] => 3 ) ) Array ( [in] => Array ( [0] => 1 [2] => 3 ) ) -- Edit bug report at http://bugs.php.net/?id=30179&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30179&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30179&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30179&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30179&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30179&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30179&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30179&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30179&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30179&r=support Expected behavior: http://bugs.php.net/fix.php?id=30179&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30179&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30179&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30179&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30179&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30179&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30179&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30179&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30179&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30179&r=mysqlcfg
