PHP to read and write scores
Open the PHP files you downloaded from this tutorial (right click -> Edit with Notepad) and update the database part according to the data of your account - like the two images shown below.
(You can find this data also on Software/Services -> MySQL -> "List of your current databases and users")
Repeat this step with both php files: 'savescores.php' and 'getscores.php'
Next step. Go to your CPanel and access your File Manager. Here you can upload files, images, sounds, games, etc... This is where the PHP files will be saved.
Notice the 'DO NOT UPLOAD HERE'. You should click "public_html" directory and save there your files. To UPLOAD your php files, click the "Upload" button and select 'savescores.php' and also 'getscores.php'
Reading scores (testing our PHP)
Use your domain assigned to your account and type on your internet browser (Google Chrome, Firefox, etc) the following:
If you can see the 'best scores' you previously saved on the database, you have set it up correctly. Congratulations!
The server part is ready. Now you only need to set up Construct 2.
