getimagesize() 错误：“无法打开流：没有这样的文件或目录”

Question

我有这个问题，我不知道该怎么办？

这是我的脚本：

这个错误的信息是：

警告：getimagesize(localhost/uploads/ad88ba4cacfa04317e7b56db59f9815b_t.jpg)：无法打开流：C:\wamp\www\js\ajaximage.php 第 122 行中没有这样的文件或目录

但是这张图片已经上传并存在.. 到底是什么？

122 行：

$height = getimagesize($site_url.'/uploads/'.$photo_n.'_t.jpg');

请帮忙..我不明白：/

应@usandfriends 的要求:)

我假设您已经从 tmp 位置移动了文件，然后尝试使用 var_dump(getcwd()) 检查当前工作目录，也许 ../uploads 指向其他地方
