imagecreatefromjpeg和类似功能在PHP中不起作用 [英] imagecreatefromjpeg and similar functions are not working in PHP

问题描述

我已经进行了搜索，过去的问题中提供的解决方案对我来说是完全无法理解的.每当我运行imagecreatefromjpeg之类的函数时，都会得到此信息:

I’ve searched for this and the solutions provided in past questions are completely incomprehensible to me. Whenever I run functions like imagecreatefromjpeg, I get this:

严重错误:调用未定义的函数imagecreatefromjpeg()...

Fatal error: Call to undefined function imagecreatefromjpeg() ...

我正在开发新版本的PHP；我的上次安装从未遇到此问题.我不知道发生了什么.

I’m working on a new install of PHP; my last installation never had this problem. I don’t get what’s going on.
