There i found the method which need some changes inside the php.ini which is out of my access (host server not local server). Alternatively you could set them dynamically from inside your script using ini_set().
If you don't have permission, then ask your host. Hosts prevent access for good reason. As their servers get bogged down with ridiculously long processes like shifting GB sized files!
my website is uploaded to webhost which in UK, so how i can access that host php.ini file. its not possible for client. im the ower of my domain name+hosting and i have full access to my pleskcontrol pannel. Could you help now how i increase the upload file size from 1 MB to atlest 2MB progammatically.
