这篇文章主要介绍了php上传图片存入数据库示例,需要的朋友可以参考下
大部分人的图片上传都是保存一个路径到数据库,这样在插入时确实快,,也符合web的特点,但是在删除时就很麻烦,需要找到文件并删除,该代码能够把代码直接存入数据库,删除时一并删除。请注意:这样的话数据库大小会激增,请酌情使用
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-Image
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'];
$tmp=$_FILES["file"]["tmp_name"];
$fp = fopen($tmp,'rb');
$data = bin2hex(fread($fp,$size));
$dsn='mysql:host=localhost;dbname=test';
echo '
';<br> try{<br> $pdo = new PDO($dsn,'root','root');<br> $pdo->exec("INSERT INTO `upload`(`type`,`data`) values ('$type',0x$data)");<br> $id = $pdo->lastInsertId();<br> echo 'upload success!<a href="view.php?id='.%24id.'">View</a>';<br> $pdo = null;<br> }catch (PDOException $e){<br> echo $e->getMessage();<br> }<br> echo '';
fclose($fp);
}
view.php
复制代码 代码如下:
$id = $_GET['id'];
if(is_numeric($id)){
$dsn='mysql:host=localhost;dbname=test';
try{
$pdo = new PDO($dsn,'root','root');
$rs = $pdo->query('select * from `upload` where `id`='.$id);
$row = $rs->fetchAll();
$data = $row[0];
header("Content-Type:${data['type']}");
echo $data['data'];
$pdo = null;
}catch (PDOException $e){
echo $e->getMessage();
}
}else{
exit();
}
