產品價格顯示爲69英鎊，而不是來自MYSQL數據庫的PHP 69.00英鎊

這裏的一個奇怪的問題是，當循環從數據庫中提取的產品時，某些產品價格顯示爲完整的整數。例如69英鎊，但有些正確顯示爲69英鎊。我不知道爲什麼一些產品顯示正確，而其他產品則不正確。產品價格顯示爲69英鎊，而不是來自MYSQL數據庫的PHP 69.00英鎊

我的數據庫中的價格列是十進制（10,2），所有產品的所有值都包含2個小數點。

我將向您展示我在前端顯示數據時所採取的步驟，儘可能詳細地說明相關細節。

$pageContent = getHomeContent($conn); 


function getHomeContent($conn) 
{ 
    $topProducts = getTopProducts($conn); 
    //I do more here but nothing relevant to my problem 

    $homeContent = [ 
     'topProducts' => $topProducts 
    ]; 

    return $homeContent; 
} 


function getTopProducts($conn) 
{ 
    $companyId = companyId(); //returns an integer 
    $products = []; 

    $sql = "SELECT products.id, products.name,products.description, products.feature_image , products.price, products.slug,products.special_offer,products.special_offer_start , category.slug as category_slug 
     FROM products 
     JOIN category_product ON products.id = category_product.product_id 
     JOIN category ON category.id = category_product.category_id WHERE products.company_id = ". $companyId ." 
     ORDER BY products.amount_sold DESC LIMIT 3"; 

    $result = $conn->query($sql); 

    if ($result->num_rows > 0) { 
     // output data of each row 
     while($row = $result->fetch_assoc()) { 
      $products[] = $row; 
     } 
    } 
    return $products; 
}

與數據我根本就一個foreach是這樣的：

<?php 
    foreach($pageContent['topProducts'] as $product){ 
     ?> 
     <div class="col-xs-12 col-sm-4"> 
      <article class="product"> 
       <img src="<?= $product['feature_image'] ?>" class="img-responsive"/> 
       <span class="green-header">&pound;<?= $product['price'] ?></span> 
      <!-- More goes here but again, its not relevant to my problem -->     
      </article> 
     </div> 
     <?php 
    } 
?>

現在，當我的print_r（pageContent）數組是這樣的：

Array 
(
    [topProducts] => Array 
     (
      [0] => Array 
       (
        [id] => 136 
        [name] => product name 
        [description] => product description 
        [feature_image] => product url 
        [price] => 69 
        [slug] => product-slug 
        [special_offer] => 0 
        [special_offer_start] => 2013-03-19 
        [category_slug] => product slug 
       ) 

      [1] => Array 
       (
        [id] => 136 
        [name] => product name 
        [description] => product description 
        [feature_image] => product url 
        [price] => 69.00 
        [slug] => product-slug 
        [special_offer] => 0 
        [special_offer_start] => 2013-03-19 
        [category_slug] => product slug 
       ) 

      [2] => Array 
       (
        [id] => 136 
        [name] => product name 
        [description] => product description 
        [feature_image] => product url 
        [price] => 78.00 
        [slug] => product-slug 
        [special_offer] => 0 
        [special_offer_start] => 2013-03-19 
        [category_slug] => product slug 
       ) 

     ) 
)

沒有人有任何想法？

使用number_format()函數的價格。 Click這裏檢查功能

<span class="green-header">&pound;<?= number_format($product['price'],2) ?></span>

謝謝，這對我有用。但似乎是解決方法，並沒有真正說出爲什麼會發生這種情況。你有什麼主意嗎？ –

我建議這個解決方案，因爲你提到一些記錄工作，有些不是，從number_format（）函數我們嚴格的所有記錄顯示與預期的格式。 – Mujahidh

不管從什麼數據庫進來，你總是可以使用PHP的內置數字格式。這是在這種情況下要走的路。原因是，當PHP看到69.00的值時，它會自動將它轉換爲int，因爲它沒有任何有意義的分數部分。所以爲了讓你的分數只使用像這樣的數字格式：

<?php 
     $price = number_format($product['price'],2); 
     <span class="green-header">&pound;<?php echo price; ?></span>
