By default, PHP file upload size is set to maximum 2MB file on the server, but you can increase or decrease the maximum size of file upload using the PHP configuration file (php.ini), this file can be found in different locations on different Linux distributions.

# vim /etc/php.ini                   [On Cent/RHEL/Fedora]
# vim /etc/php/7.0/apache2/php.ini   [On Debian/Ubuntu]

To increaes file upload size in PHP, you need to modify the upload_max_filesize and post_max_size variable’s in your php.ini file.

upload_max_filesize = 10M
post_max_size = 10M

In addition, you can also set the maximum number of files allowed to be uploaded simultaneously, in a single request, using the max_file_uploads. Note that from PHP 5.3.4 and laster versions, any upload fields left blank on submission do not count towards this limit.

max_file_uploads = 25

The variable post_max_size which is used to set the maximum size of POST data that PHP will accept. Setting a value of 0 disables the limit. If POST data reading is disabled via enable_post_data_reading, then it is ignored.

Once you have made the above changes, save the modified php.ini file and restart the web server using following commands on your respective Linux distributions.

--------------- SystemD --------------- 
# systemctl restart nginx
# systemctl restart httpd		
# systemctl restart apache2	

--------------- Sys Vinit ---------------
# service nginx restart
# service httpd restart		
# service apache2 restart

How to change the maximum upload file size for PHP scripts

This article describes how to change the maximum upload file size for PHP scripts by using the upload_max_filesize and post_max_size php directives.

Changing the maximum upload file size

By default, the maximum upload file size for PHP scripts is set to 128 megabytes. However, you may want to change these limits. For example, you can set a lower limit to prevent users from uploading large files to your site. To do this, change the upload_max_filesize and post_max_size directives.

To ensure that file uploads work correctly, the post_max_size directive should be a little larger than the upload_max_filesize. For example, the following settings demonstrate how to set a file upload limit to 20 megabytes:

upload_max_filesize = 20M
post_max_size = 21M

To verify the current value of the upload_max_filesize directive and other directives, you can use the phpinfo() function. For more information, please see this article.

Setting the directives

The preferred way to set php directives is using the graphical tools in the control panel.

For accounts using the cPanel control panel, see this article.

For accounts using the Plesk control panel, see this article.

Many accounts also allow the use of a custom php.ini file. For instructions to create a custom php.ini file, see this article.
