Modify PHP settings

PHP settings can be changed and configured using php.ini file. This blog will give you few common examples.

In PHP applications there are some case in which we might need to allow for larger upload files. Such as videos, plugins or large database files. In order to upload large amount of data into your PHP application you need to edit the php.ini file with the following command (This example shows the path for Apache on Ubuntu 14.04.):

sudo nano /etc/php5/apache2/php.ini

The default lines that control the file size upload are:

php.ini

post_max_size = 8M
upload_max_filesize = 2M

You can change your desired maximum file upload size with these default values.  For example, if you needed to upload a 60MB file you would changes these lines to:

php.ini

post_max_size = 60M
upload_max_filesize = 60M

If you want to increase the amount of memory limit PHP can use, you can set by memory_limit:

php.ini

memory_limit = 128M

or max_execution_time, which defines how many seconds a PHP process can run for:

php.ini

max_execution_time = 30

When php.ini is configured then you can save the changes and exit php.ini file

Now restart the web server to enable the changes that you have just made. For Apache on Ubuntu 14.04, this command will restart the web server:

sudo service apache2 restart

Now create file info.php and write the following lines:

<?php
phpinfo();
?>

Now refresh the page info.php and you will see the changes has been updated that you have made.
