This article mainly introduces the example analysis of the daily average index tree according to the reference, which has a certain reference value, and interested friends can refer to it. I hope you will gain a lot after reading this article. Let the editor take you to know it.

$array = array (0 = > array ('id'= > 1pyrrhenium)), 2 = > array (' id'= > 3MYRIMUIDOID = > 1primer menus = > 1 submenu menus urlations = > 0)), 1 = > array ('id'= > 2precepts = > 0menus), 1 = > menus = > 2menus = > 0menus = > 0menus = > 0menus 3 = > array ('addtime'= >' 2018-08-29 16 purl 3615 55'), 3 = > array ('id'= > 4 recordings menunameplates = > 3 memorials = > 1 sub-menus 2 minute codes addtimepieces = > 0 camera addtimepieces = >' 2018-08-29 16 VR 36 rigs 55'), 4 = > array ('id'= > 5 parcels menunamees = > 2 submenus 1 minutes title urlations = > 0 minutes urlums = > 2018-08-29 16 purport 3655'),) Function getTree ($items,$pid = "uid") {$map = []; $tree = []; foreach ($items as & $it) $map [$it ['id']] = & $it; / / the ID name of the data generates a new reference index tree foreach ($items as $k = > & $at) {$parent = & $map [$at [$pid]; if ($parent) {$parent [' children'] [] = & $at } else {$tree [] = & $at;}} return $tree;} print_r (getTree ($array)); die

The effect is

Array ([0] = > Array ([id] = > 1 [uid] = > 0 [menuname] = > menu 1 [url] = > 0 [addtime] = > 2018-08-29 16:36:55 [children] = > Array ([0] = > Array) ([id] = > 3 [uid] = > 1 [menuname] = > 1 submenu 1 [url] = > 0 [addtime] = > 2018-08-29 16:36:55 [children] = > Array ([0] = > Array ([id] = > 4) [uid] = > 3 [menuname] = > 1 submenu 2 [url] = > 0 [addtime] = > 2018-08-29 16:36:55 )) [1] = > Array ([id] = > 2 [uid] = > 0 [menuname] = > menu 2 [url] = > 0 [addtime] = > 2018-08 -29 16:36:55 [children] = > Array ([0] = > Array ([id] = > 5 [uid] = > 2 [menuname] = > 2 submenu 1 [url] = > 0 [addtime] = > 2018-08-29 16:36:55) Thank you for reading this article carefully I hope the article "sample Analysis of Index Tree based on reference" shared by the editor will be helpful to everyone.
