It is kind of strange because as far as I expect it is supposed to be the same result as in the line where $e is being var_dumped. var_dump($e) gives correct result: array 'a' => array 0 => 'aa' 1 => 'aa' 'b' => array 0 => 'bb' 1 => 'bb' and var_dump($f) gives notece message and result is array 'a' => 'aa' 'b' => 'bb' problem appears in 4.3.1 too, but not in 4.2.2 Reproduce code: --------------- <?php $c=array('a' => 'aa','b' => 'bb'); $d=array('a' => 'aa','b' => 'bb'); $a=$c; $b=$c; $f=array_merge_recursive($a,$b); var_dump($f); $e=array_merge_recursive($c,$d); var_dump($e); ?> Expected result: ---------------- array 'a' => array 0 => 'aa' 1 => 'aa' 'b' => array 0 => 'bb' 1 => 'bb' array 'a' => array 0 => 'aa' 1 => 'aa' 'b' => array 0 => 'bb' 1 => 'bb' Actual result: -------------- Warning: array_merge_recursive(): recursion detected in c:\servak\www\tests\array_merge_recursive.php on line 9 array 'a' => 'aa' 'b' => 'bb' array 'a' => array 0 => 'aa' 1 => 'aa' 'b' => array 0 => 'bb' 1 => 'bb' ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24198&edit=1
