A client of mine wants a website. I'm gonna base it on PHP and MySQL, but have just found out that his hosting dosen't support MySQL databases I however, have a load of databases waiting to be used in my hosting cpanel. Is their a way I can link a file from his hosting space, to my database? If this dosen't work, is there a way I can add MySQL to his hosting without upgrading/paying? Here is the hosting package my client is using: http://www.heartinternet.co.uk/starter-h.shtml
If you have a dedicated server or VPS it's quite easy to to do. Just have MySQL listen on a TCP/IP port. Point Client's PHP at your server and you're done. Personally I would just recommend buying a better hosting account.
Buy a better hosting account that has got MySQL. Otherwise something will change one day and it will all stop working and you'll spend ages working out why.
