has fastcgi solutions. FastCGI can make the PHP process heavy Reuse rather than each new request to restart a process. FastCGI can also allow several processes to execute at the same time. This solves both The problem of the CGI process mode consumption is too large, and the use of the CGI process mode does not exist the advantage of thread security problems. Therefore, if you are using ISAPI to run PHP, you must use the

resources among threads within a unified process is shown in the following table:1.3 Threading ModelModern operating systems combine a user-state and a kernel-state threading model in which the user-state execution system is responsible for switching between non-blocking processes within the process, while the kernel-state operating system is responsible for blocking the switching of threads, i.e. simultan

Thread: is the smallest unit of the Windows Task Scheduler. A thread is an execution flow in a program, each with its own proprietary register (stack pointers, program counters, etc.), but the code area is shared, that is, different threads can execute the same function, and in one application it is often necessary to use multiple threads to handle different things, which can improve the efficiency of the p

. This thread pool supports the need to schedule and periodically perform tasks.

operation has a lock, both read and write operations wait. Read operation is only a write operation waiting.The volatile keyword can guarantee the visibility of your data. Not a lock. And while in use, try to ensure that it is an identifier while (flag) {}. Where flag can be visible. Because volatile does not guarantee atomic operation. This keyword guarantees that the write operation of a variable precedes the read operation of the variable.
