problem is clear, it is not very difficult to solve this problem. The common mode current on the cable is caused by the following reasons: common mode current caused by differential mode current leakage. even if the cable contains a signal return line, it cannot guarantee that the signal current is 100% returned from the return line. In particular, when the frequency is high, various stray parameters in the space provide the third line for the signal current, more return paths. Although this co

In this paper, two diagrams are used to sort out the knowledge of TCP-IP protocol. The TCP communication process consists of three steps: establishing a TCP connection channel, transmitting data, and disconnecting a TCP connection channel. 1 shows the TCP communication process.

Like Java, Nodejs, should be on the server to continue to run a program, the program will run, will occupy the CPU, will consume memory, received network requests, will be processed.
and PHP does not seem to be a program, more like HTML, only open when the execution, when no one to access PHP services, PHP even a little bit of memory, a little CPU is not accounted for, is this it?
If so, wouldn't it be difficult for PHP to encapsulate the database class? Because each user comes in to give him t
