PHP图像上载和调整大小错误

我在网站上查找问题的解决方案，但找不到答案。希望有人能在这方面帮助我：

我有一个脚本，可以在不刷新页面的情况下上传图像并调整其大小。我在网上找到了它，并根据我的使用情况进行了调整。脚本可以在下面找到

我的问题：

首先，upload.php脚本工作正常，但我知道错误号为9

我自己是怎么解决的：

在本地计算机和服务器上尝试了它，两者都给出了相同的错误号9

删除了所有$\u POST并设置了“静态”变量，但不起作用，仍然得到了第9个变量

有人能帮我吗，tnx

尝试删除此行中的@：

 if(!@imagejpeg($im,$dir.$file,100)){

---

它抑制imagejpeg抛出的错误。如果没有它，您可能会看到问题所在。

从以下行中删除

@

：

  if(!@imagejpeg($im,$dir.$file,100)){

@

抑制错误。如果它被删除并且启用了

display\u errors

，您应该会看到更具描述性的错误消息

我猜是由于权限不足，

imagejpeg（）

无法写入该文件。

该死

我很愚蠢：(

正如我建议的那样，我去掉了@，亲眼看到了我做错了什么

错误出现在我的目录结构中，如下所示

|主文件夹| |_|子文件夹| |upload.php ||图像文件夹|

$dir=$\u POST['uploadPath']；

是一个将文件移动到“mainfolder/subfolder/imageFolder”的文件夹，但它必须是“imageFolder/”，因为我在“subfolder”中使用upload.php文件

谢谢你的帮助

如果结果是内存问题（始终是我的第一个赌注），请记住3000 x 3000像素JPG占用的内存不是9 MB，而是至少3 x 3000 x 3000=27 MB。

  if(!@imagejpeg($im,$dir.$file,100)){
