High-score solution, Phpstudy 2013 Database configuration problems
I got someone else's project, and now I want to get familiar with it, but I personally do the front-end (the kind that started learning), PHP learned a day yesterday.
Now want to configure an environment locally, so that I can modify the front-end things, and then I looked up on the internet using Phpstudy to do, put all the files in the WWW folder, through the local localhost access. But I have not configured the database (I guess because of this problem), so can access, but a lot of data interaction is not possible (such as the application account).
So what I want to ask is how do I do it now? is to check his PHP first, and then according to what he wrote, building a database? If so, should I go through the global search for this sentence mysql_connect (Servername,username,password);

By the way, ask this table is phpstudy default, what is the use of it?
------to solve the idea----------------------
Phpstudy just helps you integrate the PHP operating environment.

You don't have the data, maybe.
The address of the database, account number, password account to not all the original project is not connected to the database, nature will not be able to read the data
------to solve the idea----------------------
You have to get the database structure for it, and import or create the corresponding database, and then fill in the project with the configuration information of the connection database.

Your databases are from MySQL, so you don't have to worry about them.
------to solve the idea----------------------
If you have a test database you can connect directly, you can also directly connected to the use.
If not, you can only set up a database server in this machine, and establish the corresponding database.
