<?php 

$servername = "localhost"; 
$username = "username"; 
$password = "password"; 

// create connection 
$conn = new mysqli($servername, $username, $password); 
// check connection 
if ($conn->connect_error){ 
    die("connection failed: " . $conn->connect_error); 
} 
// connect to DB 
$db_selected = mysqli_select_db('article', $conn); 
if (!$db_selected){ 
    die("can't use article : " .mysqli_error()); 
} 
// extract databases table to PHP array 
$query = "SELECT * FROM `articles`"; 
$result = mysqli_query($query); 
$number = mysql_numrows($result); 
$article_array = array(); 
$x = 0 
while($x < $number) 
{ 
    $row = mysqli_fetch_array($result); 
    $artic = $row['name']; 
    $amount = $row['quantity']; 
    $article_array[$artic] = $amount; 
    $x++; 
} 
echo count($article_array); 
//echo "hello"; 

<? 

即使回聲你好不會工作和IM不知道如果我應該把一個名稱和數量：

$artic = $row['name']; 
$amount = $row['quantity']; 

Answer 1

你是混合過程的風格面向對象。您的查詢和循環應該是這樣的：

$query = "SELECT * FROM `articles`";  
$result = $conn->query($query); 
$article_array = array(); 
while($row = $result->fetch_array(MYSQLI_ASSOC)){ 
    $artic = $row['name']; 
    $amount = $row['quantity']; 
    $article_array[$artic] = $amount; 
}

而且你的PHP關閉標籤是錯誤的 - 應該是?>或省略。
