从数据库获取数组到json_encode

Question

我试图展示这样的数组（显示id_supplier和nama_supplier）

{"1":"PT Kesatu","2":"PT Kedua","3":"PT Ketiga","4":"PT Keempat"}

来自supplier表。我使用了以下代码：

$query = mysql_query("SELECT id_supplier, nama_supplier FROM supplier ORDER BY nama_supplier");  
$supplier = array();
while($row = mysql_fetch_object($query)){
$supplier = $row;
}
echo json_encode($supplier);

但它只是向我显示了1条记录，结果就像这样

{"id_supplier":"5","nama_supplier":"PT Unggas Makmur"}

Answer 1

这将是：

while($row = mysql_fetch_object($query)){
$supplier[] = $row; // not only $supplier - [] will automatically increment the index
}

Answer 2

使用[]数组。

$query = mysql_query("SELECT id_supplier, nama_supplier FROM supplier ORDER BY nama_supplier");  
$supplier = array();
while($row = mysql_fetch_object($query)){
$supplier[] = $row;
}
echo json_encode($supplier);

Answer 3

您需要使用[]数组：

$query = mysql_query("SELECT id_supplier, nama_supplier FROM supplier ORDER BY nama_supplier");  
$supplier = array();
while($row = mysql_fetch_object($query)){
$supplier[] = $row; // not only $supplier ,but [] will increment, and get all the values
}
echo json_encode($supplier);
