Multiple PHP array traversal

  • 772

Hello, friends, how are you, I have problems like going through this json, I don't know if it is multiple or dimensional, there we go, I am consuming a web service and it returns me that json where it shows me 2 main arrays and within each array there are more arrays, 1 or more for go through the main arrays I do a for and for the secondary ones I do another for but the issue is that when it has only one array inside the main one it does not show but in case it has more than 1 one yes, I do not know if I will be doing it right.

In the image shows the json, the correct thing should be that the seat 19473575 only shows 1 time and the other seat 15120251 is showing the 3 that I have inside.

Any suggestion would be very helpful.

{"listarAsientosResponse":{"asientos":{"transaccion":13978138,"nroTotalPag":4,"listAsientos":[{"idImgAsiento":19473575,"numPag":1,"tipo":"ASIENTO","listPag":{"nroPagRef":4,"pagina":1}},{"idImgAsiento":15120251,"numPag":3,"tipo":"ASIENTO","listPag":[{"nroPagRef":1,"pagina":1},{"nroPagRef":2,"pagina":2},{"nroPagRef":3,"pagina":3}]}]}}}

    Well, answering myself, I just solved it, I forgot to put it here too, in case someone has this little problem in the future.

    //ARRAY Y VER SI ES TIENE 1 O MAS
$datoasiento  = $ressunartdetalle['listarAsientosResponse']['asientos']['listAsientos'];
$logitudasiento = count($datoasiento); // TAMAÑO DEL ARRAY

// SI ES UN ARRAY NO ES NECESARIO EL FOR

//En el primer for es para hacer el recorrido de los array principales
//En el segundo for es para recorrer los arrays secundarios dentro de los principales y también si solo tiene 1 o mas array secundarios

//El isIndexedasientos  lo uso para ver si tiene 1 o mas arrays secundarios.

 for ($i = 0; $i < $logitudasiento; $i++) {
        $nroTotalPagVarios   = $ressunartdetalle['listarAsientosResponse']['asientos']['listAsientos'][$i]['numPag'];
        $valor   = $ressunartdetalle['listarAsientosResponse']['asientos']['listAsientos'][$i]['listPag'];
        $isIndexedasientos = array_values($valor) === $valor;
        for ($k = 0; $k < $nroTotalPagVarios; $k++) {
            if ($isIndexedasientos == null) {
                echo $datoasiento[$i]['idImgAsiento'] . "-" . $datoasiento[$i]['numPag'] . "-" . $datoasiento[$i]['tipo'] . "-" . $datoasiento[$i]['listPag']['nroPagRef'] . "-" . $datoasiento[$i]['listPag']['pagina'] . "<br>";
            } else {
                echo $datoasiento[$i]['idImgAsiento'] . "-" . $datoasiento[$i]['numPag'] . "-" . $datoasiento[$i]['tipo'] . "-" . $datoasiento[$i]['listPag'][$k]['nroPagRef'] . "-" . $datoasiento[$i]['listPag'][$k]['pagina'] . "<br>";
            }
        }
    }

    In the first for is to traverse the main arrays. In the second for is to go through the secondary arrays within the main ones and also if it only has 1 or more secondary arrays.

    Ok guys, that's how I fixed it.
