问题描述
我没有使用PHP连接到数据库的问题，但是在我测试的一些脚本中，我已经看到了一个小的差别在connect命令。
I have no problem connecting to a database using PHP however in some scripts I have tested, I have seen a small difference in the connect command.
@mysql_connect 与 mysql_connect之间有什么区别 ？
我在编写自己的脚本时从未使用过 @ 符号，所以只是想知道它是否有用
I have never used the @ symbol when writing my own script so was just wondering if it served a purpose.
提前感谢
推荐答案
@ 符号在函数前面沉默它。意思是，即使执行失败，也不会得到任何类型的错误信息。所以我建议：不要使用它
The @ symbol in front of a function silences it. Meaning, you won't get any types of error messages when executing it, even if it fails. So I suggest: don't use it
另外，作为@AlexanderLarikov说，不要使用 mysql_ * ，社区已开始对该功能进行。
In addition as @AlexanderLarikov said, don't use mysql_* anymore, the community has started to depreciate that function.
