求教:使用PHP的函数fpassthru()显示图片详解
新学PHP,可能没问到点子上,大概意思是这样的:

wamp环境,zend框架+smarty模板

1.求教:使用PHP的函数fpassthru()显示图片详解,该怎么处理 然后在action里边用fpassthru传递一个图片来显示 是否可行? 怎么写?

2. 不用img标签 用fpassthru 可以传递图片到前台么?

------解决方案--------------------
...Action{
//1可以直接输出图片内容例如用你说的fpassthru:

PHP code
// 以二进制格式打开文件$name = './img/ok.png'$fp = fopen($name, 'rb');// 发送合适的报头header("Content-Type: image/png");header("Content-Length: " . filesize($name));// 发送图片并终止脚本fpassthru($fp);exit;<br><font color="#e78608">------解决方案--------------------</font><br>apache 下防盗链可以用rewrite_module,用这些输出文件头的方法来处理只会让服务器负担加重.<br><br>http://sealbird.iteye.com/blog/976891<br><font color="#e78608">------解决方案--------------------</font><br>
探讨

楼上发的昨天我也搜到过,不过试了下,没成功 不知道是哪里的问题

后边的'rb' 应该是参数吧 这个参数我查了手册没查到 所以想来提问一下看看有没有更有用的资料

------解决方案--------------------
注释掉 header("Content-Length: " . filesize($imgpath));

header("Content-Type: image/jpg");
后,只能是图片数据流
