简单地从数据库检索图像名称

Question

我想检索存储在数据库中的图像..我只是试图打印图像的名称，现在我甚至尝试显示图像，以便我可以变得更好在此...

现在我有一个表称为类别与领域categories_id，categories_image

这是我在php查询：

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

echo $category_image_raw['categories_image']; ?> 

领域CATEGORY_ID 41上载到图像它。这是行不通的。我错过了什么？

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']; 
?> 

记得先登录到mysql。
