首先，我知道这些关于“memory_limit”错误的问题已经被问了好几次，并且给出的大多数解决方案都涉及 ini_set 修改，但我认为这不是我的情况。

事实上，我确实收到了：[21-Apr-2013 22:21:48 UTC] PHP 致命错误：在 /home/xxx/public_html/www4/admincenter 中允许的内存大小为 52428800 字节已用尽（试图分配 16000 字节） /clientes/102/slides/nuevo_slide.php 第 20 行

如您所见，允许的总内存大小实际上大于函数尝试分配的大小，但我仍然收到相同的错误：\ 据我所知，imagecreatefromjpeg 函数应该有问题（如错误行指出：20）

这是我的代码：顺便说一下，它适用于 img1 而不是 img2：

  • img1 = 139kb，1000 x 300 像素
  • img2 = 648kb，4000 x 3000 像素

两个大小都在允许的内存之下。我真的很感谢你在这方面的帮助。谢谢！
