i want to upload image to database..

Answer 1

Read this very nice example here: http://www.mysqltutorial.org/php-mysql-blob/ Also see this image gallery example here: http://www.anyexample.com/programming/php/php_mysql_example__image_gallery_(blob_storage).xml

BLOBs are data types in MySql database which can help you store image files in database directly.

Although a better way would be to store the file on the disk and store the path of that variable in the database.

Answer 2

get the Content of the file and save in database;

$image = addslashes(file_get_contents($_FILES['image']['tmp_name']));

Mysql:

$sql = "INSERT INTO `product_images` (`id`, `image`) VALUES ('1', '{$image}')";

Answer 3

首先，如果要将整个图像保存到数据库中，必须将pic属性类型设置为BLOB，这里有两个选项，要么将整个图像保存到数据库中，要么将图像上传到数据库后保存名称。指定的文件夹，每个文件夹具有唯一的名称，因此您可以按名称将图像检索到该目录中。
