How to increase my upload limit in php

[shadowx]

I read so many articles out there in the internet and found that to change the php.ini file to upgrade the upload limit. But I do all the suffs and cant upload more than 10mb of files or so. I am trying to add a feature to upload video file through the front end for users. But failed for some reasonIs there any other way to do it. Or is it because it is a video file or some thing like that
