What can I send back to the browser while I wait for PHP execution?
- by Matt Malesky
So....I have a PHP page that involves a lot of backend execution, namely 'exec' calls to run shell commands on the host server.
This can take upwards of a few minutes depending on the calls involved. (If you look below, each recursion through the exec calls is mounting a LUN; I'd like to sometimes do upwards of 100 per execution.) I'm curious on what I can do to send content back to the browser (and prevent it from timing out).
