Or just use the PEAR    installer with <strong class="command">pecl install sqlite</strong>.   SQLite itself is already included, You do not need to install   any additional software.  </p>  <p class="para">   Windows users will enable <var class="filename">php_sqlite.dll</var> inside   of <var class="filename">php.ini</var> in order to use these functions.   The <acronym title="Dynamic Link Library">DLL</acronym> for this <acronym title="PHP Extension and Application Repository">PECL</acronym> extensionmay be downloaded from either the <a href="http://www.php.net/downloads.php" class="link external">&raquo; PHP Downloads</a> page or from <a href="http://pecl4win.php.net/" class="link external">&raquo; http://pecl4win.php.net/</a>  </p>  <p class="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 <var class="filename">php.ini</var> (because it is now bundled as   shared). Moreover, since PHP 5.1.0 SQLite depends on <a href="intro.pdo.html" class="link">PDO</a> it must be enabled too, by adding the   following lines to <var class="filename">php.ini</var> (in order):   <div class="informalexample">    <div class="example-contents"><div class="cdata"><pre>extension=php_pdo.dllextension=php_sqlite.dll</pre></div>    </div>   </div>   On Linux or Unix operating systems, if you build PDO as a shared   extension, you must build SQLite as a shared extension using the   <strong class="command">--with-sqlite=shared</strong> configure option.  </p>  <p class="para">   SQLite 3 is supported through <a href="ref.pdo-sqlite.html" class="link">PDO SQLite</a>.  </p>  <blockquote><p><b class="note">Note</b>:    <b>Windows installation for unprivileged accounts</b><br />       On Windows operating systems, unprivileged accounts don&#039;t have the    <var class="varname">TMP</var> 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 <var class="varname">TMP</var> 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 <strong class="command">SetEnv</strong> directive in your <var class="filename">httpd.conf</var> file. For    example:    <div class="informalexample">     <div class="example-contents"><div class="cdata"><pre>SetEnv TMP c:/temp</pre></div>     </div>    </div>    If you are unable to establish this setting at the server    level, you can implement the setting in your script:    <div class="informalexample">     <div class="example-contents"><div class="phpcode"><code><span style="color: #000000">putenv('TMP=C:/temp');</span></code></div>     </div>    </div>    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:    <span class="computeroutput">     malformed database schema -     unable to open a temporary database file for storing temporary tables    </span>   <br />  </p></blockquote> </div><hr /><div style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="sqlite.setup.html">Installing/Configuring</a></div> <div class="next" style="text-align: right; float: right;"><a href="sqlite.configuration.html">Runtime Configuration</a></div> <div class="up"><a href="sqlite.setup.html">Installing/Configuring</a></div> <div class="home"><a href="index.html">PHP Manual</a></div></div></body></html>
