How to check internet speed using PHP?

Question

PHP

Hello colleagues! Recently faced with the following problem:
There is an FTP server with movies, a TV and a main server that receives files from the FTP server and makes them available through the TV. I want to show on the screen before the start of the download approximately the time the movie was downloaded to the main server. I can get the weight of the movie in bytes using the ftp_size() function, but I also need information about the download speed. How to recognize her?
Many thanks in advance to everyone who helps
