Some website display random quotes to its visitors on various pages. The following snippet shows how to display a random quote(when ever the function is invoked) out of list of quotes that are pre populated into the arrary.
As a further extension the quotes can be loaded from a newline delimited file (one quote per line) or from a database and then stored into global variable array which can be passed into this get_random_quotes
function to get the next random quote.
* This simple snippet can be used to display
* a random quote.
// define an array that lists out the quotes
'A liar always a liar',
'God is truth'
// generate a random no between 0 and size of quotes array -1
// as the index starts with 0
$random_no = rand(0,sizeof($quotes)-1);
// get the quote corresponding to random no generated
$quote = $quotes[$random_no];
