PHP函数是否区分大小写？ [英] Are PHP functions case sensitive?

问题描述

我正在挖掘一些代码，并且发现了一些对 mySQL_fetch_array 的调用。 PHP对函数名称是否区分大小写？

I was digging through some code, and I found some calls to mySQL_fetch_array. Is PHP case sensitive about function names? I recall reading this somewhere but can't seem to find any reference to it.

推荐答案

是一种很好的形式来调用函数，因为
出现在其声明中。

Note: Function names are case-insensitive, though it is usually good form to call functions as they appear in their declaration.
