Using the PHP shuffle() function

The PHP shuffle() function is useful if, for example, you want to extract random items from a database.

Here is a very simple script showing how to use shuffle().

<?php

$name = array('John', 'Michael', 'Steven', 'Angela', 'Henry', 'Stuart', 'Peter', 'Nathalie', 'Susan', 'Maria');

shuffle($name);

print $name[0];
?>

This script displays one name from those contained in the array called $name.

The names are initially loaded into the array, they are then shuffled using the shuffle() function, and then the first item in the array is printed to the screen.

If you go to www.computernostalgia.net, you can see an example of how the shuffle() command is being used to randomly display photos (on the home page) from a database.

If you want the code for this, send me an email (john at dixondevelopment.co.uk) and I'll send it to you.
