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

Use the following outline to connect and begin querying the MySQL server from within your PHP scripts. Remember if you are a Pixel Internet customer you cannot connect to your databases remotely for security reasons; you can only connect from localhost.

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 your 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.

Thats it!
