The module is not already loaded, I think it gave an error. I completely deleted the files. This is the path I followed while installing. gave some errors like zend_hash
cd /usr/local/src
wget https://download.suhosin.org/suhosin-0.9.38.tar.gz
tar zxvf suhosin-0.9.38.tar.gz
cd suhosin-0.9.38
phpize
./configure
make
make install
echo extension=suhosin.so >> /usr/local/php/php.ini
