How many databases can php connect to at once?

[8mycsh]

I have a project where I want to use php to search to 300 mysql databases. Is this possible? Does anyone know the number of databases php can connect to at once? or isn't there a limit.

Thanks for your help.

My guess is that you're going to run into system resource problems on the server and coding nighmares before you have a problem with mySQL. Why are there 300 databases? Do you mean 300 tables? If so, are they normalized? That may help.
