How do I query a MySQL database from a PHP script?

Back to Help Main Page

Use the following outline to connect and begin querying the MySQL server from within your PHP scripts. You should connect to localhost for database connections, not the external IP or hostname of the server..

1. Connect to the MySQL Server

Use the following statement to connect to the database server. Substitute the username and password for those that have been created in the control panel and have given adequate permissions to this database.

mysql_connect('localhost','USERNAME','PASSWORD');

2. Select Your Database

Use the following statement to select the database you wish to connect to. Make sure you substitute your database name.

mysql_select_db("DATABASENAME");

3. Executing A Query

You are now ready to execute your queries. Most problems that arise with your scripts will be caused by incorrect permission settings or syntax errors within the code.

mysql_query("QUERY");

4. Close the connection

Once your script has finished with the database, it should close the connection.

mysql_close();
