The SQLite 2 driver for PDO is provided primarily to make it easier to import legacy SQLite 2 database files into an application that uses the faster, more efficient SQLite 3 driver. As a result, the SQLite 2 driver is not as feature-rich as the SQLite 3 driver. </para> <note> <para> PDO_SQLITE allows using strings apart from streams together with <constant>PDO::PARAM_LOB</constant>. </para> </note> </section> &reference.pdo-sqlite.configure; </partintro> <refentry xml:id="ref.pdo-sqlite.connection"> <refnamediv> <refname>PDO_SQLITE DSN</refname> <refpurpose>Connecting to SQLite databases</refpurpose> </refnamediv> <refsect1 role="description"> &reftitle.description; <para> The PDO_SQLITE Data Source Name (DSN) is composed of the following elements: <variablelist> <varlistentry> <term>DSN prefix (SQLite 3)</term> <listitem> <para> The DSN prefix is <userinput>sqlite:</userinput>. <itemizedlist> <listitem> <para> To access a database on disk, append the absolute path to the DSN prefix. </para> </listitem> <listitem> <para> To create a database in memory, append <literal>:memory:</literal> to the DSN prefix. </para> </listitem> </itemizedlist> </para> </listitem> </varlistentry> <varlistentry> <term>DSN prefix (SQLite 2)</term> <listitem> <para> The <link linkend="ref.sqlite">SQLite</link> extension in PHP 5.1 provides a PDO driver that supports accessing and creating SQLite 2 databases.
