If you want to fix the IP address of the network interface, there are currently three methods: one is to modify the IP address through each release and version-specific tool, and the other is to modify the configuration file of the network interface directly, and the third is to modify the specific file and add the ifconfig instruction to specify the IP address of the NIC. For example, in Redhat or Fedora, the name of the I

2. Call at the end

Or

Two forms mean one thing.The advantage of this is that you do not need to consider the number of ESP equal to, the number of PUSH times, and the number of POP times, because we know that the EBP contains the ESP value at the beginning.

As we all know, the goal of OOP is to write code once, copy, copy, inherit, inherit, and then inherit to make reasonable use of every job, and also facilitate code management. Find the link where an error occurs. However, sometimes the class we write finds that it is only used once and does not generate multiple instances. At this time, the new method will not only affect the efficiency, but the code is not concise enough.
Therefore, php, which is very emotional, provides us with a convenient a
