youdontmeanmuch Posted January 12, 2009 Share Posted January 12, 2009 Per the example array at the very bottom, i want to be able to append the depth of each embedded array inside of the array. for example: array ( 53 => array ( 'title' => 'Home', 'path' => '', 'type' => '118', 'pid' => 52, 'hasChildren' => 0, ), Has a depth of one according to the sample array shown below so it should now look like this: array ( 53 => array ( 'title' => 'Home', 'path' => '', 'type' => '118', 'pid' => 52, 'hasChildren' => 0, 'depth' => 1, ), and so on... All of the recursive array function attempts i have made are pretty embarrassing. However I have looked at RecursiveArrayIterator which has the getDepth function. I'm confused on how to append it to the current array... any help is VERY much appreciated, thank you. <?php $example = array ( 52 => array ( 'title' => 'Website Navigation', 'path' => '', 'type' => '115', 'pid' => 0, 'hasChildren' => 1, 'children' => array ( 53 => array ( 'title' => 'Home', 'path' => '<front>', 'type' => '118', 'pid' => 52, 'hasChildren' => 0, ), 54 => array ( 'title' => 'Features', 'path' => 'features', 'type' => '374', 'pid' => 52, 'hasChildren' => 1, 'children' => array ( 59 => array ( 'title' => 'artistic', 'path' => 'features/artistic', 'type' => '374', 'pid' => 54, 'hasChildren' => 1, 'children' => array ( 63 => array ( 'title' => 'galleries', 'path' => 'features/artistic/galleries', 'type' => '374', 'pid' => 59, 'hasChildren' => 1, 'children' => array ( 65 => array ( 'title' => 'graphics', 'path' => 'features/artistic/galleries/graphics', 'type' => '118', 'pid' => 63, 'hasChildren' => 0, ), 67 => array ( 'title' => 'mixed medium', 'path' => 'features/artistic/galleries/mixed-medium', 'type' => '118', 'pid' => 63, 'hasChildren' => 0, ), 64 => array ( 'title' => 'overview', 'path' => 'features/artistic/galleries', 'type' => '118', 'pid' => 63, 'hasChildren' => 0, ), 68 => array ( 'title' => 'photography', 'path' => 'features/artistic/galleries/photography', 'type' => '118', 'pid' => 63, 'hasChildren' => 0, ), 66 => array ( 'title' => 'traditional', 'path' => 'features/artistic/galleries/traditional', 'type' => '118', 'pid' => 63, 'hasChildren' => 0, ), ), ), 62 => array ( 'title' => 'overview', 'path' => 'features/artistic', 'type' => '118', 'pid' => 59, 'hasChildren' => 0, ), 69 => array ( 'title' => 'tutorials', 'path' => 'features/artistic/tutorials', 'type' => '374', 'pid' => 59, 'hasChildren' => 1, 'children' => array ( 71 => array ( 'title' => 'by category', 'path' => 'features/artistic/tutorials/by-category/', 'type' => '118', 'pid' => 69, 'hasChildren' => 0, ), 72 => array ( 'title' => 'by date', 'path' => 'features/artistic/tutorials/by-date/', 'type' => '118', 'pid' => 69, 'hasChildren' => 0, ), 70 => array ( 'title' => 'overview', 'path' => 'features/artistic/tutorials', 'type' => '118', 'pid' => 69, 'hasChildren' => 0, ), ), ), ), ), 58 => array ( 'title' => 'overview', 'path' => 'features', 'type' => '118', 'pid' => 54, 'hasChildren' => 0, ), 61 => array ( 'title' => 'projects / labs', 'path' => 'features/projects-labs/', 'type' => '374', 'pid' => 54, 'hasChildren' => 0, ), 60 => array ( 'title' => 'web development', 'path' => 'features/web-development', 'type' => '374', 'pid' => 54, 'hasChildren' => 1, 'children' => array ( 74 => array ( 'title' => 'articles', 'path' => 'features/web-development/articles/', 'type' => '374', 'pid' => 60, 'hasChildren' => 0, ), 73 => array ( 'title' => 'overview', 'path' => 'features/web-development', 'type' => '118', 'pid' => 60, 'hasChildren' => 0, ), 75 => array ( 'title' => 'tutorials', 'path' => 'features/web-development/tutorials', 'type' => '374', 'pid' => 60, 'hasChildren' => 0, ), ), ), ), ), 55 => array ( 'title' => 'Activity', 'path' => 'activity', 'type' => '374', 'pid' => 52, 'hasChildren' => 0, ), 56 => array ( 'title' => 'Blog', 'path' => 'blog', 'type' => '374', 'pid' => 52, 'hasChildren' => 0, ), 57 => array ( 'title' => 'About', 'path' => 'about', 'type' => '374', 'pid' => 52, 'hasChildren' => 1, 'children' => array ( 76 => array ( 'title' => 'the author', 'path' => 'about/the-author', 'type' => '118', 'pid' => 57, 'hasChildren' => 0, ), 77 => array ( 'title' => 'the website', 'path' => 'about/the-website', 'type' => '118', 'pid' => 57, 'hasChildren' => 0, ), ), ), ), ), ); print_r($example); ?> Quote Link to comment Share on other sites More sharing options...

youdontmeanmuch Posted January 12, 2009 Author Share Posted January 12, 2009 Thanks A LOT for your help... its missing the depth for items that have children. But i did find another solution here it is if anyone is curious: function array_set_depth($array, $depth = -1) { $subdepth = $depth + 1; if ($depth < 0) { foreach ($array as $key => $subarray) { $temp[$key] = array_set_depth(($subarray), $subdepth); } return $temp; } $array['depth'] = $depth; if ($array['hasChildren'] && isset($array['children'])) { foreach ($array['children'] as $key => $subarray) { $temp[$key] = array_set_depth($subarray, $subdepth); } unset($array['children']); $array['children'] = $temp; } return $array; } Quote Link to comment Share on other sites More sharing options...
