Ako vytvorit rekurzivne stromovu strukturu?

Ahojte,mam pole ktore ma napriklad takuto sturkturu:], 'b' => , 'c' => ], 'ba' => ], 'bb' => ], 'bba' => ]]a potrebujem dostat toto:, 'b' => 'ba' => ], 'bb' => 'bba' => ] ], ], 'c' => ], ],]skratka velmi primitivna zalezitost, akurat ze tu nemam napriklad informaciu o hlbke takze to musim riesit rekurzivne a uz je vecer a mne to uz nemysli.Ako by ste napisali rekurzivnu funkciu?...samozrejme tie elementy v tom poli najskor budu rozhadzane v roznom poradi.

Live demo: https://ideone.com/jT5ww7 <?php $array = ], 'b' => ], 'c' => ], 'ba' => ], 'bb' => ], 'bba' => ] ]; function expand(&$source, $item) { $result = ]; foreach($item as $key) { $result = expand($source, $source); $source = []; } return $result; } foreach($array as $key => $value) { if(!empty($array)) { $result = expand($array, $value); } } print_r($result);

Uff, tak som sa k tomu konecne dopracoval. public function processEmbeddedRegionGroups(array $groups, array &$region_element) { foreach ($groups AS $group) { ${$group->getUuid() . '_group'} = &$region_element; ${$group->getUuid() . '_parent'} = &$region_element; } foreach ($groups AS $group) { foreach ($group->getPanes() AS $pane_uuid) { // Only process groups. if (isset($groups)) { // Move the group into parent group. ${$group->getUuid() . '_group'} = ${$pane_uuid . '_group'}; // Unset the group from former parent. unset(${$pane_uuid . '_parent'}); // Set new parent. ${$pane_uuid . '_parent'} = &${$group->getUuid() . '_group'}; // Update group reference. ${$pane_uuid . '_group'} = &${$group->getUuid() . '_group'}; } } } } Vsetko su referencie takze by nemal byt problem s vykonom ani pri velkych datasetoch, co nie je moja situacia, len fyi.
