To install the Suhosin PHP extension on Debian 8 or Ubuntu 14.04 LTS, follow these steps:

1. Install the necessary dependencies:

sudo apt-get update
sudo apt-get install build-essential php5-dev

2. Download the Suhosin source code:

wget https://download.suhosin.org/suhosin-0.9.38.tgz
tar xvzf suhosin-0.9.38.tgz
cd suhosin-0.9.38

3. Compile and install the Suhosin extension:

phpize
./configure
make
sudo make install

The make install command will install the Suhosin extension to the /usr/lib/php5/20121212 directory.

4. Edit the php.ini file to enable the Suhosin extension:

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

Add the following line to the end of the file:

extension=suhosin.so

5. Restart the Apache web server to apply the changes:

sudo service apache2 restart

That's it! The Suhosin extension should now be installed and enabled on your system. You can verify that the extension is loaded by creating a PHP file with the following contents:

<?php
phpinfo();
?>

Then, open the PHP file in a web browser and look for the "Suhosin" section in the output. If the extension is installed and enabled, you should see information about the extension in this section.
