@mysql_connect和mysql_connect [英] @mysql_connect and mysql_connect

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折旧。

In addition as @AlexanderLarikov said, don't use mysql_* anymore, the community has started to depreciate that function.
