PHP Create a Multidimensional Array from an array with relational data [duplicate]

Answer 1

Following code will do the job.. you may want to tweak a bit according to your needs.

$data = array(
    '5273' => array( 'id' =>5273, 'name'=> 'John Doe', 'parent'=>''),
    '6032' => array( 'id' =>6032, 'name'=> 'Sally Smith', 'parent'=>'5273'),
    '6034' => array( 'id' =>6034, 'name'=> 'Mike Jones ', 'parent'=>'6032'),
    '6035' => array( 'id' =>6035, 'name'=> 'Jason Williams', 'parent'=>'6034')
    );

$fdata = array();


function ConvertToMulti($data) {
    global $fdata;

    foreach($data as $k => $v)
    {
        if(empty($v['parent'])){
            unset($v['parent']);
        $v['data'] = array();
        $v['children'] = array();
            $fdata[] = $v;
        }
        else {
            findParentAndInsert($v, $fdata);
        }

    }
}

function findParentAndInsert($idata, &$ldata) {

    foreach ($ldata as $k=>$v) {

        if($ldata[$k]['id'] == $idata['parent']) {
            unset($idata['parent']);
        $idata['data'] = array();
        $idata['children'] = array();
            $ldata[$k]['children'][] = $idata;
            return;
        }
        else if(!empty($v['children']))
            findParentAndInsert($idata, $ldata[$k]['children']);
    }
}


print_r($data);
ConvertToMulti($data);
echo "AFTER\n";
print_r($fdata);
