Mount Array to API

Question

Good morning to you all. I believe my question is primary, but I’m getting a lot of heat. Here in the company we will use an online ERP in which we intend to include our sales orders (using PHP) via Apis of this ERP. One of the parts of the Order Inclusion API deals with payment tranches and, according to their examples, the structure for interaction is as follows:

"lista_parcelas": {
"parcela": [
  {
    "data_vencimento": "02/10/2019",
    "numero_parcela": 1,
    "percentual": 50,
    "valor": 100
  },
  {
    "data_vencimento": "28/03/2020",
    "numero_parcela": 2,
    "percentual": 50,
    "valor": 100
  }
]

},

I tried to mount the array so:

$chave->lista_parcelas = array("parcela" => array("data_vencimento" => "31/10/2019",
						"numero_parcela" => 1,
						"percentual" => 40,
						"valor" => 120),
				"parcela" => array("data_vencimento" => "05/11/2019",
						"numero_parcela" => 2,
						"percentual" => 60,
						"valor" => 180));

But when I checked the result, only the second installment was recorded.

So I tried like this:

$chave->lista_parcelas = array("parcela" => array("data_vencimento" => "31/10/2019",
						"numero_parcela" => 1,
						"percentual" => 40,
						"valor" => 120),
				array("data_vencimento" => "05/11/2019",
						"numero_parcela" => 2,
						"percentual" => 60,
						"valor" => 180));

Thus, it gives error saying that some information is not part of the structure.

I believe it is my programming mistake. Could someone give me a light on how to correctly build this example ? Thank you in advance.

Answer 1

$a = array(

    "parcela" => array(

        array("data_vencimento" => "31/10/2019",
            "numero_parcela" => 1,
            "percentual" => 40,
            "valor" => 120),

        array("data_vencimento" => "05/11/2019",
            "numero_parcela" => 2,
            "percentual" => 60,
            "valor" => 180)

    )


);

$chave->lista_parcelas = json_encode($a);
