Question

首先，我知道有关“memory_limit”错误的这些问题已多次询问，并且大多数解决方案都涉及ini_set修改，但我不认为这是我的情况。

事实上，我正在接受： [2013年4月21日22:21:48 UTC] PHP致命错误：/ home / xxx / public_html / www4 / admincenter / clientes / 102 / slides / nuevo_slide允许的内存大小为52428800字节（试图分配16000字节）第20行的.php

正如您所看到的，允许的总内存大小实际上超过了函数尝试分配的大小，但我仍然收到相同的错误：\ 至于我能够看到imagecreatefromjpeg函数应该存在问题（如错误行所示：20）

这是我的代码：顺便说一句，它适用于img1而不是img2：

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

这两个尺寸都在允许的内存下。我真的很感谢你的帮助。谢谢！

即使memory_limit正常，PHP内存也会耗尽问题
