><P
> This is an extension for the SQLite Embeddable SQL Database Engine.
SQLite is a C library that implements an embeddable SQL database engine.
Programs that link with the SQLite library can have SQL database access
without running a separate RDBMS process.
</P
><P
> SQLite is not a client library used to connect to a big database server.
SQLite is the server. The SQLite library reads and writes directly to and from
the database files on disk.

>Installation</A
></H1
><P
> Read the INSTALL file, which comes with the package. Or just use the PEAR
installer with <B
CLASS="command"
>pear install sqlite</B
>.
SQLite itself is already included, You do not need to install
any additional software.
</P
><P
> Windows users may download the DLL version of the SQLite extension here:
(<A
HREF="http://snaps.php.net/win32/PECL_STABLE/php_sqlite.dll"
TARGET="_top"
>php_sqlite.dll</A
>).
</P
><P
> 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 <TT
CLASS="filename"
>php.ini</TT
> (because it is now bundled as
shared). Moreover, since PHP 5.1.0 SQLite depends on <A
HREF="ref.pdo.html"
>PDO</A
> it must be enabled too, by adding the
following lines to <TT
CLASS="filename"
>php.ini</TT
> (in order):
<DIV
CLASS="informalexample"
><P
></P
><A
NAME="AEN215319"

><TABLE

BGCOLOR="#E0E0E0"

><TD
><PRE
CLASS="ini"
>extension=php_pdo.dll
extension=php_sqlite.dll</PRE
></TD
></TR
></TABLE
><P
></P
></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
<B
CLASS="command"
>--with-sqlite=shared</B
> configure option.
</P
><P
> SQLite 3 is supported through <A
HREF="ref.pdo-sqlite.html"
>PDO SQLite</A
>.
</P

CLASS="note"
><P
><B
>Windows installation for unprivileged accounts: </B
>
On Windows operating systems, unprivileged accounts don't have the
<CODE
CLASS="varname"
>TMP</CODE
> 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 <CODE
CLASS="varname"
>TMP</CODE
> 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 <B
CLASS="command"
>SetEnv</B
> directive in your <TT
CLASS="filename"
>httpd.conf</TT
> file. For
example:
<DIV
CLASS="informalexample"
><P
></P
><A
NAME="AEN215331"
></A
><TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
CELLPADDING="5"
><TR
><TD
><PRE
CLASS="apache-conf"
>SetEnv TMP c:/temp</PRE
></TD
></TR
></TABLE
><P
></P
></DIV
>
If you are unable to establish this setting at the server
level, you can implement the setting in your script:
<DIV
CLASS="informalexample"
><P
></P
><A
NAME="AEN215333"
></A
><TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
CELLPADDING="5"
><TR
><TD
><code><font color="#000000">
putenv('TMP=C:/temp');</font>
</code></TD
></TR
></TABLE
><P
></P
></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:
<SAMP
CLASS="computeroutput"
> malformed database schema -
unable to open a temporary database file for storing temporary tables
</SAMP
>

</P
><P
> This option is primarily useful when you need compatibility with other
database systems, where the names of the columns are always returned as
uppercase or lowercase, regardless of the case of the actual field names
in the database schema.
</P
><P
> The SQLite library returns the column names in their natural case (that
matches the case you used in your schema). When
<CODE
CLASS="parameter"
>sqlite.assoc_case</CODE
> is set to <TT
CLASS="literal"
>0</TT
>
the natural case will be preserved. When it is set to
<TT
CLASS="literal"
>1</TT
> or <TT
CLASS="literal"
>2</TT
>, PHP will apply case
folding on the hash keys to upper- or lower-case the keys, respectively.
</P
><P
> Use of this option incurs a slight performance penalty, but is MUCH
faster than performing the case folding yourself using PHP script.
