The idea is I have a table called table with a field called field in a database called somedatabase. We have 1000 rows of data in said table and we need to pick a random result from the 1000 rows. This is just 1 way of doing it, it isnt the most optimized, neither is it the cleanest. but this will give you a basic idea of how to connect to the DB and get a result. you can expand this of course to do very tricky queries.   // Add a user variable for PDO, mysql user $user=’root’; // Add a password for PDO, mysql password $password=’password’; // Setup the mysql connection info $dsn = ‘mysql:dbname=somedatabase;host=127.0.0.1’; // Wrap the actual connection to mysql in try so if it doesn’t work you can catch the exception and echo the message. try { $dbh = new PDO($dsn, $user, $password, array(PDO::MYSQL_ATTR_INIT_COMMAND => ‘SET NAMES \’UTF8\”)); } catch (PDOException $e) { echo ‘Connection failed: ‘ . $e->getMessage(); } // Pick a number from 1 – 1000 and assign to $rc $rc = mt_rand(1, 1000); // Assign the SQL query selecting the data from our DB / field to variable $sql $sql = “SELECT field FROM table LIMIT 1 OFFSET $rc”; // run the query and for each one assign to variable $field foreach ($dbh->query($sql) as […]
