如何显示存储在MySql数据库中的BLOB图像?
我正在尝试显示上传到MySql中“存储”表的最后5张图像。我对PHP和数据库完全陌生,并且我一直在阅读有关如何做到这一点的很多文章,但是没有运气。
我可以一次存储和显示图片,但我希望能够拥有各种各样的画廊来显示最近上传的5张照片。
任何建议或帮助将不胜感激,谢谢!
附言:我知道将图片存储到这样的数据库时不赞成这样做,但是该项目仅用于实践。
index.php
<!DOCTYPE html><html>
<head>
<title>Project One</title>
</head>
<body>
<form action="index.php" method="POST" enctype="multipart/form-data">
File:
<input type="file" name="image"> <input type="submit" value="Upload">
<form>
<p />
<?php
//connect to database
(connect to server)
(select correct DB)
//file properties
$file = $_FILES['image']['tmp_name'];
if (!isset($file))
echo "please select an image.";
else
{
$image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
$image_name = $_FILES['image']['name'];
$image_size = getimagesize($_FILES['image']['tmp_name']);
if($image_size==FALSE)
echo "That's not an image.";
else
{
if (!$insert = mysql_query("INSERT INTO store VALUES ('', '$image_name', '$image')"))
echo "Problem Uploading Image.";
else
{
$lastid = mysql_insert_id();
echo "Image uploaded. <p />Your image:<p /><img src=get.php?id=$lastid>";
}
}
}
?>

get.php
<?php //connect to database

(select correct DB)
$id = addslashes($_REQUEST['id']);
$image = mysql_query("SELECT * FROM store WHERE id=$id");
$image = mysql_fetch_assoc($image);
$image = $image['image'];
header("Content-type: image/jpeg");
echo $image;
?>
回答:
这就是我很久以前想做类似的事情了!= P
$sql = "SELECT image FROM table WHERE cond ORDER BY xxxx DESC LIMIT 5";$result = mysqli_query($db,$sql);
while($arraySomething = mysqli_fetch_array($result))
{
echo "<img src='php/imgView.php?imgId=".$arraySomething."' />";
}
