Previous Comments: ------------------------------------------------------------------------ [2004-12-21 04:25:01] fire at firepages dot com dot au Description: ------------ in php4 array_merge_recursive($arr1,$arr...) allowed the first array argument to be unassigned , in php5 it requires inintialising. perhaps php4 behaviour was a feature-bug ? Reproduce code: --------------- while( $whatever ){ $arr = foo->get_arr(); $tmp = array_merge_recursive( $tmp , $arr ) ; } Expected result: ---------------- $tmp is created if !exists & continues as expected Actual result: -------------- PHP-4.3.8 >> $tmp is created if !exists & continues as expected PHP-5.0.3 Warning: array_merge_recursive() Argument #1 is not an array in .... easily solved by initialising $tmp prior to use $tmp=array(); just unsure if this is intended ? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31216&edit=1
