PHP函数和@functions [英] PHP functions and @functions

问题描述

基本上，我已经看到人们在调用函数之前使用@，不是针对每个函数，而是针对诸如file_get_contents()，mysql_connect()之类的某种扩展功能.

Basically, I've seen people using @ before their function calls, not for every function, but for some kind of extension functions like file_get_contents(), mysql_connect() and so on.

是的，问题是:函数调用之前这些@是出于什么目的?

And yes, the question is: For what purpose are there these @s before function calls?

换句话说，@file_get_contents()和file_get_contents()有什么区别?

Or in other words, what is the difference between @file_get_contents() and file_get_contents()?

推荐答案

@是错误控制运算符.基本上是在抑制错误.

@ is an error control operator. Basically it's suppressing errors.
