<!-- {{{ Requirements -->
<section xml:id="sqlite.requirements">
&reftitle.required;
<para>
In order to have these functions available, you must compile PHP with
SQLite support, or load the SQLite extension dynamically from your
&php.ini;.
</para>
</section>
<!-- }}} -->
<!-- {{{ Installation -->
<section xml:id="sqlite.installation">
&reftitle.install;
<para>
Read the INSTALL file, which comes with the package. Or just use the PEAR
installer with <command>pecl install sqlite</command>.
SQLite itself is already included, You do not need to install
any additional software.
</para>
<para>
Windows users will enable <filename>php_sqlite.dll</filename> inside
of &php.ini; in order to use these functions.
&pecl.windows.download;
</para>
<para>
In PHP 5, the SQLite extension and the engine itself are bundled and
compiled by default. However, since PHP 5.1.0 you need to manually
activate the extension in &php.ini; (because it is now bundled as
shared). Moreover, since PHP 5.1.0 SQLite depends on <link
linkend="intro.pdo">PDO</link> it must be enabled too, by adding the
following lines to &php.ini; (in order):
<informalexample>
<programlisting role="ini">
<![CDATA[
extension=php_pdo.dll
extension=php_sqlite.dll
]]>
</programlisting>
</informalexample>
On Linux or Unix operating systems, if you build PDO as a shared
extension, you must build SQLite as a shared extension using the
<command>--with-sqlite=shared</command> configure option.
</para>
<para>
SQLite 3 is supported through <link
linkend="ref.pdo-sqlite">PDO SQLite</link>.
</para>
<note>
<title>Windows installation for unprivileged accounts</title>
<para>
On Windows operating systems, unprivileged accounts don't have the
<varname>TMP</varname> environment variable set by default. This will
make sqlite create temporary files in the windows directory, which is
not desirable. So, you should set the <varname>TMP</varname> environment
variable for the web server or the user account the web server is
running under. If Apache is your web server, you can accomplish this via
a <command>SetEnv</command> directive in your &httpd.conf; file. For
example:
<informalexample>
<programlisting role="apache-conf">
<![CDATA[
SetEnv TMP c:/temp
]]>
</programlisting>
</informalexample>
If you are unable to establish this setting at the server
level, you can implement the setting in your script:
<informalexample>
<programlisting role="php">
<![CDATA[
putenv('TMP=C:/temp');
]]>
</programlisting>
</informalexample>
The setting must refer to a directory that the web server
has permission to create files in and subsequently write
to and delete the files it created.
Otherwise, you may receive the following error message:
<computeroutput>
malformed database schema -
unable to open a temporary database file for storing temporary tables
</computeroutput>
</para>

</section>

<!-- {{{ Configuration -->
&reference.sqlite.ini;
<!-- }}} -->
<!-- {{{ Resources -->
<section xml:id="sqlite.resources">
&reftitle.resources;
<para>
There are two resources used in the SQLite Interface. The first one is the
database connection, the second one the result set.
