Displaying stream progress in PHP
Hannes Van de Vreken has written a tutorial on how to display stream progress in PHP.
Opposite to HTTP requests, tasks run from the command line aren’t supposed to return instantly. They can take a very long time. Imagine a task that loops an entire database table or a task that references an external source repetitively, or maybe a taks that performs a large file transfer. It’s very important to show the issuer what is actually going on, or he/she will be left in the dark for minutes/hours. "Is this task still running?", "How long has this thing been running yet?", "Is it almost done?", "Is it running out of memory?"https://hannesvdvreken.com/2015/05/12/stream-progress/
