PHP itself does not have multiple threads, but it can be curved to create the same effect, such as a multiple-process approach to asynchronous invocation, limited to command mode. There is also a simpler way to use the WEB program, which is to request a URL with Fsockopen (), fputs (), without waiting for a return, if you do something in the requested page (URL) that is asynchronous. The key code is as follows: Copy Code code as follows: $fp = Fsockopen (' localhost ',80, $errno,
