22. Connecting to a Database through PHP <?php include 'DBconfig.php'; include 'DBopen.php'; // ... do something like insert or select, etc ?>

23. Closing a Database through PHP <?php // an example of closedb.php // it does nothing but closing // a mysql database connection mysql_close($conn); ?> <?php include 'config.php'; include 'opendb.php'; // ... do something like // insert or select, etc include 'dbclose.php'; ?>

24. Listing data in a database using PHP To get PHP to execute MySQL statements we must use the mysql_query() function. This function is used to send a query or command to a MySQL connection. e.g.: Using PHP you can run a MySQL SELECT query to fetch the data out of the database. You have several options in fetching information from MySQL. PHP provide several functions for this. The first one is mysql_fetch_array() which fetches a result row as an associative array , a numeric array , or both. Below is an example of fetching data from MySQL, the table contacts has three columns; cF name , c Lname and c Age .

25. Listing data in a database using PHP <?php include 'DBconfig.php'; include 'DBopen.php'; $query = &quot;SELECT cFname, cLname, cAge FROM contacts&quot;; $result = mysql_query($query); while($row = mysql_fetch_array($result, MYSQL_ASSOC)){ echo &quot;First Name: $row[Fname] <br>&quot;. &quot;Second Name: $row[Lname] <br>&quot;. &quot;Age: $row[age] <br><br>&quot;; } include 'DBclose.php'; ?>
