This article mainly introduces you to the method of obtaining the current millisecond timestamp in PHP. I hope it can help you.
Recently I am working on the backend of a smart home project. It is necessary to upload the user's configuration information of smart devices to the server in real time in order to achieve synchronization. Therefore, the accuracy of the time is relatively high. At first, I used PHP directly. The time() function is used to obtain the timestamp. The time obtained is accurate to the second level. If the clients operate at the same time, conflicts may still occur. Therefore, it is recommended to increase the timestamp accuracy to the millisecond level. However, there is no built-in function in PHP to obtain it. Millisecond timestamp, but a microtime() function is provided. If called without optional parameters, this function returns a string in the format of "msec sec", where sec is the Unix epoch since 0:00:00 January 1 , 1970 GMT) since now, msec is the microsecond part. Both parts of the string are returned in seconds.
