+ <para>
+ There were some changes in PHP 5 regarding databases (MySQL and SQLite).
+ </para>
+ <para>
+ In PHP 5 the MySQL client libraries are not bundled, because of licence
+ problems and some others. For more information, read the <link
+ linkend="faq.databases.mysql.php5">FAQ entry</link>.

+ <para>
+ There is also a new extension, <link linkend="ref.mysqli">MySQLi (Improved

+ </para>
+ <para>
+ Since PHP 5, the <link linkend="ref.sqlite">SQLite</link> extension is
+ built-in PHP. SQLite is embeddable SQL database engine and is not a
+ client library used to connect to a big database server (like MySQL or
+ PostgreSQL). The SQLite library reads and writes directly to and from the
+ database files on disk.

+ In PHP 5 there is a new Object Model. PHP's handling of objects has been
+ completely rewritten, allowing for better performance and more features.
