Increment an array with PHP foreach

Question

I have a foreach that where I need to add the value of the variable to a array:

foreach ($xml->NFe->infNFe->det as $itens){    
    $quantidade = round($itens->prod->qCom);
    $total_quant_unidade = array();
    array_push($total_quant_unidade, $quantidade);
}

The problem is that only the ultimate value is added even within the foreach.

Answer 1

The total_quant_unit variable must be outside the foreach

$total_quant_unidade = array();

foreach ($xml->NFe->infNFe->det as $itens){    
    $quantidade = round($itens->prod->qCom);
    array_push($total_quant_unidade, $quantidade);
}
