Edit /etc/php5/apache2/php.ini, set upload_max_filesize and post_max_size to 150M and restart Apache:

sudo service apache2 restart

You should then be able to upload your SQL dump using phpMyAdmin.

Once you’ve done that, it’s safer to lower the size limit back to a reasonable value like 8M or so. Don’t forget to restart Apache after editing php.ini.

I uploaded and imported file: Orders.sql of 700mb to Database: myshop from OSX Terminal:

scp ~/Downloads/Orders.sql root@MY_SSH_IP:/root/Orders.sql
ssh root@MY_SSH_IP
mysql -u root -p myshop < Orders.sql

Delete the uploaded file:

rm /root/Orders.sql

After Several hours trying to figure out why changes to php.ini doesn’t work on max upload size, i decided to take other path…so here goes the....

Ways of making work changes to uploadmaxfilesize, or php.ini max upload size doesn’t work:

FIRST remember to also increase postmaxsize just in case is that the limit as that one overrides uploadmaxfilesize…

Here goes the ways to make work uploadmaxfilesize without touching PHP.ini!!!!

Add next content to .htaccess file at your app or site directory:

<IfModule mod_php5.c>
phpvalue uploadmaxfilesize 40M
value postmaxsize 40M


Add this to the conf file of the site or application (usually at /etc/nginx/sites-available)

location ~ .php$ {
fastcgiparam PHPVALUE “uploadmaxfilesize = 50M \n postmaxsize=51M”;


CREATE A FILE user.ini (where user is the user that have access to that folder, usually files are owned by this user) put this file on the directory where the php is located, user.ini must have next content:

uploadmaxfilesize = 40M

postmaxsize = 40M


Inside the php that must upload the file or files at the top inside php brackets of course, put:

iniset(‘postmaxsize’, '64M’);
set('uploadmaxfilesize’, '64M’);

One of this solutions must work, in my case was the Apache one, and worked perfect, try yours!!!

I tried all mentioned above. But it is not working :(
My current php version is PHP6 where file import in db is not working.
My my initial php version, it is working absolutely fine - PHP 5
please suggest

Hello, all

You can create a php info file in order to check the current values and check which is the php.ini file in use. Create the following file in your public_hmtl folder - phpinfo.php and put the following code inside it:


You can also use the following command in order to find the location of the php.ini file:

php -i | grep php.ini

The output will be:

Configuration File (php.ini) Path => /etc/php/7.2/cli
Loaded Configuration File => /etc/php/7.2/cli/php.ini

Then check for the current value of uploadmaxfilesize you can also check which is the configuration file - php.ini that is currently used and apply the changes there (if the site using the global php.ini file and you change the values for these settings this will make the changes globally for all sites). Ideally you would like to have the following values:

upload_max_filesize = 200M

You also need to restart your web server in order the changes to take effect.

Hope that this helps!

To Increase Upload File Size Limit Via FTP:

  1. Login with your SSH root password.

  2. Choose SFTP and connect.
    within /etc folder search for php.ini file and change the three php.ini files in the following folders

/php/7.2/apache2/ folders

(depending on php version, folders might be different)

memorylimit 128M
maxsize 128M
max_filesize 128M

Restart Apache Server
