其中db_mysql.inc.php,config.php,function.php不是真正使用到的,關鍵是$filename 檔案名稱,我是通過讀取資料庫中的圖片名稱。
include_once ('inc/db_mysql.inc.php'); include_once ('inc/config.php'); include_once ('class/function.php'); global $picPath; if (strstr($_SERVER[HTTP_USER_AGENT],"MSIE")) { $attachment = ''; } else { $attachment = ' atachment;'; } $image = getInfo('newssp_gallery','id',$_GET['id']); $filename = $picPath.$image['filename']; if (!file_exists($filename)) { $filename = $picPath."notexist.gif"; } header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1 header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache");// HTTP/1.0 header("Content-disposition:".$attachment." filename=".$image['original']); $size = @filesize($filename); header("Content-Length: $size"); $fd = @fopen($filename,rb); $contents = @fread($fd,$size); @fclose ($fd); echo $contents; ?>

使用的時候可以把在html檔案裡加上:498)this.width=498;' onmousewheel = 'javascript:return big(this)' src='showpic.php?id=xxx' width='50' height='50'>
showpic.php及上面的那個php檔案,id=xxx是資料庫裡的記錄ID,width是縮圖的寬,height是縮圖的高,請不要同時寬高都上,例如,你要實現寬為50的縮圖,只要498)this.width=498;' onmousewheel = 'javascript:return big(this)' src='showpic.php?id=xxx' width='50'>這樣就可以了。
