upload large files with php nginx

Question

I would like to upload relatively big file via a php api (around 4M). In the beginning of my php5 script I set the following options :

ini_set("upload_max_filesize","100M");
ini_set("post_max_size","108M");
ini_set("max_execution_time","3000");
ini_set("memory_limit","500M");
ini_set("max_input_time","3000");
ini_set("output_buffering","0");

plus I add the following params to nginx config file:

client_max_body_size 500M; 
fastcgi_read_timeout 600s;
keepalive_timeout 3000; 
client_header_timeout 1000m;
client_body_timeout 1000m;
client_header_buffer_size 2k;

And this has slightly improved the situation as I had this error:

POST Content-Length of 78014353 bytes exceeds the limit of 8388608 bytes in Unknown on line 0

And now, my error occurs a bit later on the process (when I try to move an un-uploaded file with the function moveTo of Slim framework)

error exception 'RuntimeException' with message '  is not a valid uploaded file'

Do you have some suggestions on what I could try to fix it?

Edit:

I forget to precise that the upload works well as long as the archive file to upload is small (<2M)

Edit 2:

I try to modify the file /etc/php5/fpm/php.ini instead of modifying the parameters directly on my php script, but I get the following issue.

After restarting php5-fpm and nginx, my new paramaters are not taken into account:

>>php5-fpm -i | grep "post_max"
post_max_size => 8M => 8M

Nevertheless it seems that I modify the good configuration file:

>>php5-fpm -i | grep "php.ini"
Configuration File (php.ini) Path => /etc/php5/fpm
Loaded Configuration File => /etc/php5/fpm/php.ini

I try to check if some other ini files overwriting my change were loaded:

root@test2:~# php5-fpm -i | grep ".ini"
Configuration File (php.ini) Path => /etc/php5/fpm
Loaded Configuration File => /etc/php5/fpm/php.ini
Scan this dir for additional .ini files => /etc/php5/fpm/conf.d

But I did not find my parameters being explicitly redefined in any of this files...

did you check destination folder permissions ? and do you have any validation on MIME Type or file extension ? — teeyo, Oct 05 '17 at 14:57

I don't think you can set this in script. Because this has to go through PHP-FPM first. So the settings need to be there in php.ini first — Tarun Lalwani, Oct 05 '17 at 16:09
@TarunLalwani I actually have troubles when I try to modify the php.init file, I will had something on my question message to explain it — Sophie Jacquin, Oct 06 '17 at 08:12

I finally found the solution on a relative stack overflow question : Changes to upload_max_filesize in Ubunutu php.ini will not take effect

So, what has work for me was to follow the advices of Jekis:

Folow these steps to resolve the issue:

Eval phpinfo(); Search for 'Scan this dir for additional .ini files' text in phpinfo() output It will be something like this /etc/php5/apache2/conf.d

Create your user.ini file inside the dir. (/etc/php5/apache2/conf.d/user.ini)

Use this ini file for custom settings.

Restart the server

This is because:

The newest php version installed on server does not allow global settings (such as execution time, max upload filesize, max post file size, etc.) to be changed.
