php array access issue

Question

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]
        }
    }
}

well true but there is not the problem, it doesn't do what its supposed — user3557451

It's rather ambiguous what you want to express with that activos[key][value] notation; a print_r sample of your actual array would say a lot more. — deceze

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;
        }
    }
}

$key & $value overwriting here :)

$t = 0;
foreach ($activos as $key => $value) {
  foreach ($pagos as $key1 => $value1) {
      if($activos[$value] == $pagos[$key1]){
          $t += $pagos[$key1];
      }
  }
}

I thinks this is what you need

$t = 0;
foreach ($activos as $key => $value) {
    foreach ($pagos as $key1 => $value1) {
        if($value == $key1){
            $t += $value1;
        }
    }
}
