【问题描述】：
我在代码中遇到提取问题。该语句无法返回 $row[] 中的值。我之前已经声明了变量，但结果中只能显示一个变量。这是我的代码：
<?php
//require_once('function.php');
//session_start();
//if (!is_user()) {
// redirect('signin.php');
//}
$page_title = "Purchase Order";
include_once 'header.php';
$no_po = $_GET['no_po'];
// include database and object files
include_once 'config/database.php';
//$total_harga = $harga_jual * $qty;
// instantiate database and product object
$database = new Database();
$db = $database->getConnection();
$query = "SELECT
po.no_po,
barang.nama_barang,
klien.nama_klien,
po.tgl_po,
po.qty,
barang.harga_jual,
po.status_po,
po.keterangan,
surat_pengantar.tgl_kirim,
gudang.nama_gudang,
barang.harga_jual * po.qty AS total_harga
FROM
public.po,
public.barang,
public.klien,
public.good_receipt,
public.gudang,
public.surat_pengantar
WHERE
no_po = :no_po AND
po.id_barang = barang.id_barang AND
po.id_klien = klien.id_klien AND
po.no_po = surat_pengantar.no_po AND
po.no_po = good_receipt.no_po AND
gudang.id_gudang = good_receipt.id_gudang";
$stmt = $db->prepare( $query );
$stmt->bindParam(':no_po',$no_po);
$result = $stmt->execute();
$no_po ;
$nama_barang=null;
$harga_jual=null;
$qty=null;
$nama_klien=null;
$total_harga=null;
$status_po=null;
$tgl_po=null;
$tgl_kirim=null;
$nama_gudang=null;
$keterangan=null;
while($row = $stmt->fetch(PDO::FETCH_ASSOC)){
$no_po = $row['no_po'];
$nama_barang = $row['nama_barang'];
$nama_klien = $row['nama_klien'];
$tgl_po = $row['tgl_po'];
$qty = $row['qty'];
$harga_jual = number_format($row['harga_jual'],0,",",".");
$status_po = $row['status_po'];
$keterangan = $row['keterangan'];
$tgl_kirim = $row['tgl_kirim'];
$nama_gudang = $row['nama_gudang'];
$total_harga = number_format($row['total_harga'],0,",",".");
}
