php阵列访问问题

I have two arraws where I'm storing some data: activos[key][value] and pagos[key][value]

the operation I want to do is for each "activo" element get the value and where it coincides with the key on pagos sum the value of this array to a variable.

I've tryed with this but it doesn't work as it is supposed to:

$t = 0;
foreach ($activos as $key => $value) {
    foreach ($pagos as $key => $value) {
        if($activos[$value] == $pagos[$key]){
            $t += $pagos[$key]
        }
    }
}

    You've already key and value from both arrays, but you've erased them !!

    $t = 0;
    foreach ($activos as $keyActivos => $valueActivos) {
        foreach ($pagos as $keyPagos => $valuePagos) {
            if($valueActivos == $keyPagos){
                $t += $valuePagos;
            }
        }
    }
