簡單地從數據庫檢索圖像名稱

Question

我想檢索存儲在數據庫中的圖像..我只是試圖打印圖像的名稱，現在我甚至嘗試顯示圖像，以便我可以變得更好在此...

現在我有一個表稱爲類別與領域categories_id，categories_image

這是我在php查詢：

<?php 
$category_image_raw = "select c.categories_image from categories c where c.categories_id in(41)"; 

echo $category_image_raw['categories_image']; ?> 

領域CATEGORY_ID 41上載到圖像它。這是行不通的。我錯過了什麼？

Answer 1

<?php 
$category_image_sql = "select c.categories_image from categories c where c.categories_id = 41;"; 
$category_image_query = mysql_query($category_image_sql); 
$category_image_raw = mysql_fetch_array($category_image_query); 
echo $category_image_raw['categories_image']; 
?> 

記得先登錄到mysql。
