PHP $_files getting file size issues

Why do I use $_files this gets the uploaded file size more than 2MB can not get the size of the file?
Can be obtained at less than 2MB
Is it related to the setup in php.ini?

It's about the setup in php.ini.

Yes, upload_max_filesize change to 100M.

More than the size of the php.ini set, it is not only $_files $_post $_get and so on all failure

Yes, of course! You can set a bit, or you can look at the error message, you know why not see the uploaded files, it is recommended to $_files,var_dump out!
