php下将图片以二进制存入mysql数据库中并显示的实现代码_PHP教程

If($Picture != "none") { 
$PSize = filesize($Picture); 
$mysqlPicture = addslashes(fread(fopen($Picture, "r"), $PSize)); 
mysql_connect($host,$username,$password) or die("Unable to connect to SQL server"); 
@mysql_select_db($db) or die("Unable to select database"); 
mysql_query("INSERT INTO Images (Image) VALUES ($mysqlPicture)") or die("Cant Perform Query"); 
}else { 
echo"You did not upload any picture"; 
} 
 
//以img标签读取数据库中的图片的代码 
 代码如下:

mysql_connect($host,$username,$password) or die("Unable to connect to SQL server"); 
@mysql_select_db($db) or die("Unable to select database"); 
$result=mysql_query("SELECT * FROM Images") or die("Cant Perform Query"); 
While($row=mysql_fetch_object($result)) { 
echo ""; 

//如secoed.php文件代码如下 
$result=mysql_query("SELECT * FROM Images WHERE PicNum=$PicNum") or die("Cant perform Query"); 
$row=mysql_fetch_object($result); 
Header( "Content-type: image/gif"); 
echo $row->Image;
