I have some MySQL databases on my web host. I'm trying to display only those. I have tried mysql_list_dbs but I get a list of all the dbs on my host, about 50! Is there a way to just display my databases?
You don't "have" any databases, there are a number of databases, and you have access to some of them.
I'm don't really have a clue as to why you'd want to list only the databases that you 'own', because you should already know which ones you own...
