From: [EMAIL PROTECTED] Operating system: W2K PHP version: 4.3.8 PHP Bug Type: Arrays related Bug description: Multidimensional arrays copy or array_multisort bug
Description: ------------ Seems, that multidimensional arrays are copied with one dimension, which contains references to other included arrays. I haven't found any references in manual, so this must be a bug. Reproduce code: --------------- <?php $a[0]['id'] = array(22, 12, 33, 55); $a[0]['secid'] = array("a","b","c","d"); print_r($a); $b = $a; foreach ($b as $k => $v) { array_multisort($v['id'], SORT_DESC, $v['secid'], SORT_DESC); } print_r($a); ?> Expected result: ---------------- Array ( [0] => Array ( [id] => Array ( [0] => 22 [1] => 12 [2] => 33 [3] => 55 ) [secid] => Array ( [0] => a [1] => b [2] => c [3] => d ) ) ) Array ( [0] => Array ( [id] => Array ( [0] => 22 [1] => 12 [2] => 33 [3] => 55 ) [secid] => Array ( [0] => a [1] => b [2] => c [3] => d ) ) ) Actual result: -------------- Array ( [0] => Array ( [id] => Array ( [0] => 22 [1] => 12 [2] => 33 [3] => 55 ) [secid] => Array ( [0] => a [1] => b [2] => c [3] => d ) ) ) Array ( [0] => Array ( [id] => Array ( [0] => 55 [1] => 33 [2] => 22 [3] => 12 ) [secid] => Array ( [0] => d [1] => c [2] => a [3] => b ) ) ) -- Edit bug report at http://bugs.php.net/?id=30082&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30082&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30082&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30082&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30082&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30082&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30082&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30082&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30082&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30082&r=support Expected behavior: http://bugs.php.net/fix.php?id=30082&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30082&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30082&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30082&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30082&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30082&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30082&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30082&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30082&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30082&r=mysqlcfg
