I am trying to save some data from my website to my database. This works on both my local machine and thorugh my student host: some php... $connection = @mysqli_connect('localhost', 'username', 'pw') or die (mysqli_error()); mysqli_select_db($connection, 'mydatabase') or die (mysqli_error()); some php.... I have followed all the instruction from: https://www.digitalocean.com/community/articles/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu and https://www.digitalocean.com/community/articles/how-to-install-and-secure-phpmyadmin-on-ubuntu-12-04 So i have php and mysql installed and I can access my databases through phpmyadmin I still can't save data to the database through my website using the script listed above. Any idea what might be the problem?
