I'm going to implement a website in PHP using a Web Framework. I never implemented a website in PHP... I don't have problems learning new languages. The problem is that I would like to know if frameworks like Zend, CakePHP can be used to create a page which lets you download files at a given rate (eg 50 KB/s)? Thank you.
Your server should deal with this issue, not PHP.
In case you have Apache see here:
For Lighttpd see here:
