Adapting apps to run in stackato
 Apps languages are detected automatically most of times
− On java apps Maven or ant are needed
 Provisioned service info is set put on a environment
variable inside the container

Adapting apps to run in stackato
 On php you can parse the database url using:
<?php
$url_parts = parse_url($_SERVER['DATABASE_URL']);
$db_name = substr( $url_parts['path'], 1 );
$db_connection_string = $url_parts['host'] . ':' . $url_parts['port'];
// ** MySQL settings from resource descriptor ** //
echo $db_name;
echo $url_parts['user'];
echo $url_parts['pass'];
echo $url_parts['host'];
echo $url_parts['port'];
?>
