Question

I have a one-dimensional array with (a example):

{
    ["Pagamento_valor_liquido"]=> string(3) "111"
    ["Pagamento_valor_bruto"]=> string(3) "222"
    ["TipoPagamento_id"]=> string(3) "333"
    ["TipoPagamento_descricao"]=> string(3) "444"
}

and i need help to transforme this in two sub arrays:

{
    ["Pagamento"]=> array(2) {
        ["valor_liquido"]=> string(3) "111"
        ["valor_bruto"]=> string(3) "222"
    }
    ["TipoPagamento"]=> array(2) {
        ["id"]=> string(3) "333"
        ["valor_bruto"]=> string(3) "444"
    }
}

How do it in a generic way with this pattern (Father_son_name)?

Thanks,
Celso

Answer 1

$array = array("Pagamento_valor_liquido" => "111", "Pagamento_valor_bruto" => "222", "TipoPagamento_id" => "333", "TipoPagamento_descricao" => "444");

$result = array();
foreach ($array as $k => $v) {
    $name = explode('_', $k);
    $newkey = array_shift($name);
    $newname = implode('_', $name);
    $result[$newkey][$newname] = $v;
}
var_export($result);

Seems to be pretty generic for your purpose.
