[DROID] (json) menampilkan json ke textView
cara memgambil data json dan menampilkannya dengan php
1.bikin file data.json untuk menyimpan data data json dengan ini contoh sperti ini
{"nama":"melki","umur","18"}
2.bikin file php dengan script sperti ini
<?php
//mengambil data di data.json
$file=file_get_contents("data.json");
$ambil= json_decode($file, true);
//menampilkan data
echo $ambil["nama"]."<br>";
echo $ambil["umur"];
?>
Perbedaan json_decode dan json_encode
json_decode untuk data json
json_encode untuk mengkonversi array

/*lakukan logika*/
if (!$conn) { die ('Gagal terhubung MySQL: ' . mysqli_connect_error()); }
/*kemudian kita ambil data yang ada didalam mysqli sperti ini*/
$sql = 'SELECT* FROM nama_tabel ';
$query = mysqli_query($conn, $sql);
/*lakukan logika*/
if (!$query) { die ('SQL Error: ' . mysqli_error($conn)); }
/*terahir kita tampilkan data yang sudah di ambil tadi sperti ini*/
while ($row = mysqli_fetch_array($query)){
$a=$row['nama_kolom'];
echo $a;
