<h2 class="title">Databases</h2>
<p class="para">
There were some changes in PHP 5 regarding databases (MySQL and SQLite).
</p>
<p class="para">
In PHP 5 the MySQL client libraries are not bundled, because of license
problems and some others. For more information, read the <a href="faq.databases.html#faq.databases.mysql.php5" class="link">FAQ entry</a>.
</p>
<p class="para">
There is also a new extension, <a href="ref.mysqli.html" class="link">MySQLi (Improved
MySQL)</a>, which is designed to work with MySQL 4.1 and above.
</p>
<p class="para">
Since PHP 5, the <a href="ref.sqlite.html" class="link">SQLite</a> extension is
built-in PHP. SQLite is an 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.
