If you need to connect to a mysql database from php you can do it like this:
Code language: HTML, XML (xml)
$DBH = 'localhost'; $DBU = 'root'; $DBPWD = 'password'; $DBN = 'petstore'; $conn = mysql_connect($DBH, $DBU, $DBPWD) or die ("Error: Could not connect to database."); mysql_select_db($dbname);
This allows you to make a connection to the mysql database and gets it ready for you to make queries and manipulate the data.
