一.儲存圖片的資料表結構:
---- 表的結構 `image`--CREATE TABLE IF NOT EXISTS `image` ( `id` int(3) NOT NULL AUTO_INCREMENT, `name` varchar(100) CHARACTER SET utf8 NOT NULL, `pic` blob NOT NULL, `type` varchar(50) CHARACTER SET utf8 NOT NULL, `date` datetime NOT NULL, PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;---- 轉存表中的資料 `image`--
二.php將圖片以二進位儲存到mysql資料庫中:
(1)串連資料庫檔案:conn.php:
<?php$conn = mysql_connect(‘localhost‘, ‘root‘, ‘‘);mysql_select_db(‘study‘, $conn);mysql_query("SET NAMES UTF-8");?>
(2)圖片上傳並以二進位儲存到資料庫檔案:upload.php
<?phpinclude(‘./conn.php‘);if ($_POST[‘submit‘]) { if ($_FILES[‘image‘][‘size‘]) { $names = $_FILES[‘image‘][‘name‘]; $arr = explode(‘.‘, $names); $name = $arr[0]; //圖片名稱 $date = date(‘Y-m-d H:i:s‘); //上傳日期 $fp = fopen($_FILES[‘image‘][‘tmp_name‘], ‘rb‘); $type = $_FILES[‘image‘][‘type‘]; if (!$fp) { showInfo(‘讀取圖片失敗!‘); } else { $image = addslashes(fread($fp, filesize($_FILES[‘image‘][‘tmp_name‘]))); if ($image) { $q = "insert into image (name, pic, type, date) values (‘$name‘,‘$image‘,‘$type‘,‘$date‘)"; $result = mysql_query($q); if ($result) { showInfo(‘上傳成功!‘); } else { showInfo(‘上傳失敗!‘); } } else { showInfo(‘請選擇要上傳的檔案!‘); } } } else { showInfo(‘請選擇要上傳的檔案!‘); }}function showInfo($info){ echo "<html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />"; echo "<meta http-equiv=‘refresh‘ content=‘1;url=index.php‘>"; echo "</head>"; echo "<body>" . $info . "……</body>"; echo "</html>";}?>
三.從資料庫中讀取以二進位儲存的圖片並顯示:image.php
<?phpinclude(‘./conn.php‘);$id = $_GET[‘id‘];$sql = "select * from image where id=‘$id‘";$result = mysql_query($sql, $conn);if (!$result) die("讀取圖片失敗!");$num = mysql_num_rows($result);if ($num < 1) die("暫無圖片");$data = mysql_result($result, 0, ‘pic‘);$type = mysql_result($result, 0, ‘type‘);mysql_close($id);Header("Content-type: $type");echo $data;?>
四.上傳並顯示圖片的頁面:index.php
<?phpinclude(‘./conn.php‘);?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" lang="en_US" xml:lang="en_US"><!-- * Created on 2012-10-20 * * To change the template for this generated file go to * Window - Preferences - PHPeclipse - PHP - Code Templates--> <head> <meta http-equive="Content-Type" content=text/html charset=utf-8> <title> </title> </head> <body> <form method=‘post‘ action=‘./upload.php‘ enctype="multipart/form-data"><input type="file" name="image" /><input type="submit" name="submit" value="上傳" /></form><!-----------顯示圖片---------------------><table><?php$ret = mysql_query(‘select * from image order by id desc‘);if ($ret) { while ($row = mysql_fetch_array($ret)) {?><tr><td style=‘width:170px;‘><img src="image.php?id=<?php echo $row[id];?>" width="170" height="150" border="0"><div style=‘text-align:center;‘><?php echo $row[‘name‘];?></div><?php echo $row[‘date‘];?></td></tr><?php }}?></table><!-----------/顯示圖片---------------------> </body></html>
