表结构
复制代码 代码如下:
CREATE TABLE `upload` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`type` varchar(20) NOT NULL,
`data` mediumblob NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
index.html
复制代码 代码如下:
post.php
复制代码 代码如下:
if ($_FILES["file"]["error"] > 0)
{
echo "Error: " . $_FILES["file"]["error"] . "
";
}
else
{
$type = $_FILES["file"]["type"];
$size = $_FILES['file']['size'];

$fp = fopen($tmp,'rb');
$data = bin2hex(fread($fp,$size));

echo 'upload success!View';
$pdo = null;
}catch (PDOException $e){
echo $e->getMessage();
}
echo '

view.php
复制代码 代码如下:
