Why are files larger than 2 megabytes not uploaded?

Question

Yii

There is a project on Yii, after updating php to 7.0.4, files larger than 2 megabytes stopped uploading, in php.ini upload_filesize and post_max_size are 200M each, for verification I put in Index.php phpinfo (); die (); Shows correctly, by 200M, but does not want to load files larger than 2MB.
Everything turned out to be simple, the server ran out of space and ubuntu reduced the size of tmp to 1 megabyte, so the files could not be loaded.

Answer 2

If Apache and php as a module, then you need:
either in php.ini

post_max_size=20M
upload_max_filesize=20M

either in .htaccess / httpd.conf / virtualhost include

php_value post_max_size 20M
php_value upload_max_filesize 20M

Answer 3

I don’t remember about Apache, but nginx has a limit on uploading files.
Look at the web server.
Alternatively, model validation
