Cara Menghuraikan JSON sebagai Array atau Objek dalam PHP

Menghuraikan JSON dengan PHP

JSON ialah format data popular yang sering digunakan untuk bertukar-tukar data antara aplikasi web dan API. Dalam PHP, fungsi json_decode() boleh digunakan untuk menghuraikan rentetan JSON ke dalam tatasusunan atau objek PHP.

Untuk menghuraikan JSON sebagai objek, hanya gunakan sintaks $json = json_decode($data). Objek yang terhasil kemudiannya boleh diakses menggunakan notasi titik.

Walau bagaimanapun, jika anda ingin menghuraikan JSON sebagai tatasusunan, anda perlu menghantar argumen kedua true kepada fungsi json_decode(). Ini akan mengembalikan tatasusunan bersekutu yang mana kuncinya ialah nama sifat dan nilainya ialah nilai yang sepadan.

Pertimbangkan data JSON berikut sebagai contoh:

{
    "kind": "shopping#products",
    "etag": "\"T9uPnY2MZMB71TDpKXXZdr3yWX4/qtJ5vmpftFWNfijyLD9ti2Xpj-w\"",

                ],
                "images": [
                    {
                        "link": "http://ak.buy.com/PI/0/1000/219891693.jpg"
                    }
                ]
            }
        }
    ]
}

Untuk menghuraikan JSON ini sebagai tatasusunan, gunakan sintaks berikut:

<code class="php">$json = json_decode($data, true);</code>

Ini akan mengembalikan tatasusunan berikut:

[
    "kind" => "shopping#products",
