PHP 7与PHP 5 —功能更改 [英] PHP 7 vs PHP 5 — changes in functions

问题描述

我目前正在使用运行PHP 7.1.1的本地服务器XAMPP为大学分配网站，但后来我发现大学服务器运行的是旧版本的PHP服务器(我相信PHP 5.x)，并且所有我的PHP函数根本无法使用.

I'm currently building a website for my university assignment using local server XAMPP running PHP 7.1.1 but then I just found out that the university server is running an older PHP server version (I believe PHP 5.x) and all my PHP functions won't work at all.

所以我想知道:如果我想使其与大学服务器一起使用，是否只需要更改语法以匹配PHP 5.x?因为现在我不知道PHP 7.x和5.x有什么区别.

So I wonder: if I want to make it work with the university server, do I just need to change syntax to match PHP 5.x? Because now I have no idea what are the differences between PHP 7.x and 5.x.

有人可以帮我澄清一下吗?

Can anyone clarify this for me?
