視頻網站的制作例子三

The first video starts right when I open the page. As I select each movie from the list on the right, the page reloads and shows the movie I selected.

How sweet and simple was that? One Flex file, one PHP file, and a little database magic for the backend, and viola! Video sharing!

The next step is to see whether you can enhance the user experience a bit by doing more of the work in Flex.

The Flex Interface, Part 1

If you want to provide a mechanism for Flex to show any movie, you must provide the Flex application with the list of movies. The most convenient way to do that is through XML. So, going back to PHP again, you need a page exports the movie list from the database as XML. This movies.php page is shown in Listing 6.

Listing 6. movies.php

<?php
require "DB.php";

$moviebase = 'http://localhost:8080/movies/';

header( 'content-type: text/xml' );

$dsn = 'mysql://root@localhost/movies';
$db =& DB::connect( $dsn );
if ( PEAR::isError( $db ) ) { die($db->getMessage()); }
?>
<movies>
<?php
$res = $db->query( 'SELECT title, source, thumb, width, height FROM movies' );
while( $row = $res->fetchrow( ) ) {
?>
  <movie title="<?php echo( $row[0] ) ?>" source="<?php echo( $moviebase.$row[1] ) ?>" 
   thumb="<?php echo( $moviebase.$row[2] ) ?>" width="<?php echo( $row[3] ) ?>"
   height="<?php echo( $row[4] ) ?>" />
<?php
}
?>
</movies>
