If not, you likely get a PHP stack trace, informing you that the database connection failed or the INSERT statement did not work.

否则，您可能会得到一个php堆栈跟踪，告诉您数据库连接失败或者insert语句不工作。

youdao

If the client process has not explicitly issued a bind system call before initiating the connection, implicit binding on the local socket is taken care of by the stack.

如果在初始化连接之前，客户端进程没有显式发布bind系统调用，则堆栈负责本地套接字上的隐式绑定。

The activities become loosely coupled, (i.e. do not run within the same technology or call stack, under the same security authority, with a dedicated connection between them).

这些活动之间实现了松散耦合（如各活动的实现技术和调用堆栈可以不同，但它们之间的连接通道是专用的，安全授权等级是统一管理的）。
