upload_max_filesize doesn't change within Laravel 5.1

I'm working on multiple file upload while that time I've got an error

The file "theOne.mp3" exceeds your upload_max_filesize ini directive (limit is 2048 KiB).

So after that I've increased the post_max_size = 20M and upload_max_filesize = 20M and checked it within test.php file it shows

Even though it shows 2M within my Laravel Project and throws the error. What could be the reason behind this.
