note 114297 added to function.array-diff-assoc

an earlier post for recursive array_diff_assoc failed because isset returned false on an array element containing a null value. I updated the code so it compares null values too. <?php function array_diff_assoc_recursive($array1, $array2) { foreach($array1 as $key => $value) { if(is_array($value)) { if(!isset($array2[$key])) { $difference[$key] = $value; } elseif(!is_array($array2[$key])) { $difference[$key] = $value; } else { $new_diff = array_diff_assoc_recursive($value, $array2[$key]); if($new_diff != FALSE) { $difference[$key] = $new_diff; } } } elseif(!array_key_exists($key, $array2) || $array2[$key] != $value) { $difference[$key] = $value; } } return !isset($difference) ? 0 : $difference; } ?> ---- Server IP: 192.41.45.150 Probable Submitter: 80.113.17.58 ---- Manual Page -- http://php.net/manual/en/function.array-diff-assoc.php Edit -- https://master.php.net/note/edit/114297 Del: integrated -- https://master.php.net/note/delete/114297/integrated Del: useless -- https://master.php.net/note/delete/114297/useless Del: bad code -- https://master.php.net/note/delete/114297/bad+code Del: spam -- https://master.php.net/note/delete/114297/spam Del: non-english -- https://master.php.net/note/delete/114297/non-english Del: in docs -- https://master.php.net/note/delete/114297/in+docs Del: other reasons-- https://master.php.net/note/delete/114297 Reject -- https://master.php.net/note/reject/114297 Search -- https://master.php.net/manage/user-notes.php
