The quotes are stored in a text document. Just enter all the quotes you want to be displayed in the text document (You can use html with your quotes by simply puting the html tags within the text document.
By hitting enter in the text document you pass on to another quote.) and just include quotes.php wherever you want the quotes to be displayed on your site.
Can't be more simple than this
Can easily be integrated into any design as you just include the random quote php file where you want the quotes to be displayed.
<?PHP include('randomquotes.php '); ?>
Remember to insert this code where you want the random quotes to be displayed.
Really simple, isn't it ?
